Trier
–
Trier, formerly known in English as Treves, is a city in Germany on the banks of the Moselle. Trier lies in a valley between low vine-covered hills of red sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Moselle wine region. Founded by the Celts in the late-4th century BC as Treuorum, it was conquered by the Romans in the late-1st century BC. Trier may be the oldest city in Germany and it is also the oldest seat of a bishop north of the Alps. In the Middle Ages, the Archbishop-Elector of Trier was an important prince of the church, the Archbishop-Elector also had great significance as one of the seven electors of the Holy Roman Empire. With an approximate population of 105,000, Trier is the fourth-largest city in its state, after Mainz, Ludwigshafen, the nearest major cities are Luxembourg, Saarbrücken, and Koblenz. It is one of the five places of the state of Rhineland-Palatinate. A medieval inscription on the façade of the Red House in Trier market stated, trebetas parents were said to have been Ninus, a legendary King of Assyria invented by the ancient Greeks, and an unknown mother who was Ninuss wife before Semiramis. Semiramis took control of the kingdom upon his fathers death and Trebeta was forced into exile and his body was said to have been cremated on Petrisberg. The historical record describes the Roman Empire subduing the Treveri in the 1st century BC, the name distinguished it from the empires many other cities honoring the first emperor Augustus. The city later became the capital of the province of Belgic Gaul, after the Diocletian Reforms, it became the capital of the prefecture of the Gauls, overseeing much of the Western Roman Empire. In the 4th century, Trier was one of the largest cities in the Roman Empire with a population around 75,000, the Porta Nigra dates from this era. A residence of the Western Roman Emperor, Roman Trier was the birthplace of Saint Ambrose, sometime between 395 and 418, probably in 407 the Roman administration moved the staff of the Praetorian Prefecture about 2000 from the city to Arles. The city continued to be inhabited but was not as prosperous as before, northern Gaul was held by the Romans along a line from north of Cologne to the coast at Boulogne through what is today southern Belgium until 460. South of this line, Roman control was firm, as evidenced by the operation of the imperial arms factory at Amiens. The Franks seized Trier from Roman administration in 459, in 870, it became part of Eastern Francia, which developed into the Holy Roman Empire. Relics of Saint Matthias brought to the city initiated widespread pilgrimages, the bishops of the city grew increasingly powerful and the Archbishopric of Trier was recognized as an electorate of the empire, one of the most powerful states of Germany. The University of Trier was founded in the city in 1473, in the 17th century, the Archbishops and Prince-Electors of Trier relocated their residences to Philippsburg Castle in Ehrenbreitstein, near Koblenz

Pre-Socratic philosophy
–
Pre-Socratic philosophy is ancient Greek philosophy before Socrates and schools contemporary to Socrates that were not influenced by him. In Classical antiquity, the Presocratic philosophers were called physiologoi, Aristotle called them physikoi because they sought natural explanations for phenomena, as opposed to the earlier theologoi, whose philosophical basis was supernatural. Diogenes Laërtius divides the physiologoi into two groups, Ionian, led by Anaximander, and the Italiote, led by Pythagoras, hermann Diels popularized the term pre-socratic in Die Fragmente der Vorsokratiker in 1903. However, the term pre-Sokratic was in use as early as George Grotes Plato, edouard Zeller was also important in dividing thought before and after Socrates. Major analyses of pre-Socratic thought have been made by Gregory Vlastos, Jonathan Barnes and it may sometimes be difficult to determine the actual line of argument some Presocratics used in supporting their particular views. While most of them produced significant texts, none of the texts has survived in complete form, all that is available are quotations by later philosophers and historians, and the occasional textual fragment. The Presocratic philosophers rejected traditional mythological explanations of the phenomena they saw them in favor of more rational explanations. These philosophers asked questions about the essence of things, From where does everything come, how do we explain the plurality of things found in nature. How might we describe nature mathematically, others concentrated on defining problems and paradoxes that became the basis for later mathematical, scientific and philosophic study. Later philosophers rejected many of the answers the early Greek philosophers provided, furthermore, the cosmologies proposed by them have been updated by later developments in science. Western philosophy began in ancient Greece in the 6th century BCE, the Presocratics were mostly from the eastern or western fringes of the Greek world. Their efforts were directed to the investigation of the ultimate basis and they sought the material principle of things, and the method of their origin and disappearance. As the first philosophers, they emphasized the unity of things. Only fragments of the writings of the presocratics survive. The knowledge we have of them derives from accounts - known as doxography - of later philosophical writers, the first Presocratic philosophers were from Miletus on the western coast of Anatolia. Thales is reputedly the father of Greek philosophy, he declared water to be the basis of all things, next came Anaximander, the first writer on philosophy. He assumed as the first principle an undefined, unlimited substance without qualities, out of which the primary opposites, hot and cold, moist and dry, became differentiated. His younger contemporary, Anaximenes, took for his air, conceiving it as modified, by thickening and thinning, into fire, wind, clouds, water

Western philosophy
–
Western philosophy is the philosophical thought and work of the Western world. The word philosophy itself originated from the Hellenic, philosophia, literally, the scope of philosophy in the ancient understanding, and the writings of the ancient philosophers, were all intellectual endeavors. Western Philosophy is generally said to begin in the Greek cities of western Asia Minor with Thales of Miletus and his most noted students were respectively Anaximander and Anaximenes of Miletus. Pythagoras, from the island of Samos off the coast of Ionia, pythagoreans hold that all is number, giving formal accounts in contrast to the previous material of the Ionians. They also believe in metempsychosis, the transmigration of souls, or reincarnation, Socrates The key figure in Greek philosophy is Socrates. Socrates studied under several Sophists but transformed Greek philosophy into a unified, Socrates used a critical approach called the elenchus or Socratic method to examine peoples views. He aimed to study human things, the life, justice, beauty. Although Socrates wrote nothing himself, some of his many disciples wrote down his conversations and he was tried for corrupting the youth and impiety by the Greek democracy. He was found guilty and sentenced to death, although his friends offered to help him escape from prison, he chose to remain in Athens and abide by his principles. His execution consisting in drinking the poison hemlock and he died in 399 B. C, Plato Socrates most important student was Plato. Plato founded the Academy of Athens and wrote a number of dialogues, some central ideas of Platos dialogues are the immortality of the soul, the benefits of being just, that evil is ignorance, and the Theory of Forms. Forms are universal properties that constitute reality and contrast with the changeable material things he called becoming. Aristotle Platos most outstanding student was Aristotle, Aristotle was perhaps the first truly systematic philosopher and scientist. He wrote books on physics, biology, zoology, metaphysics, aesthetics, poetry, theater, music, rhetoric, politics, Aristotelian logic was the first type of logic to attempt to categorize every valid syllogism. Aristotelian philosophy exercised considerable influence on almost all western philosophers, including Greek, Roman, Christian, Jewish, the Neoplatonic and Christian philosophers of Late Antiquity. Early medieval philosophy was influenced by the likes of Stoicism, neo-Platonism, but, above all, the prominent figure of this period was St. Augustinianism was the preferred starting point for most philosophers up until the 13th century. The foundations of many northern European universities were built in the Middle Ages by waves of Irish, Scottish & English monks from the Celtic Church begun by Columba, see Celtic Christianity. Erigena is said to have been stabbed to death by his students with their pens and his theology would today be called pantheistic, in keeping with Celtic resolutions of pagan and Christian philosophy

Ionian School (philosophy)
–
The Ionian school, a type of Greek philosophy centred in Miletus, Ionia, in the 6th and 5th centuries BCE, is something of a misnomer. Aristotle called them physiologoi, meaning those who discoursed on nature, the classification can be traced to the second-century historian of philosophy Sotion. They are sometimes referred to as cosmologists, since they were largely physicalists who tried to explain the nature of matter, while some of these scholars are included in the Milesian school of philosophy, others are more difficult to categorize. Most cosmologists thought that, although matter could change from one form to another, later philosophers widened their studies to include other areas of thought. The Eleatic school, for example, also studied epistemology, or how people come to know what exists, but the Ionians were the first group of philosophers that we know of, and so remain historically important. Thales of Miletus is regarded as the earliest Western philosopher, before him, the Greeks explained the origin and nature of the world through myths of anthropomorphic gods and heroes. Phenomena like lightning and earthquakes were attributed to actions of the gods, by contrast, Thales attempted to find naturalistic explanations of the world, without reference to the supernatural. He explained earthquakes by imagining that the Earth floats on water, Thales most famous belief was his cosmological doctrine, which held that the world originated from water. Anaximander wrote a work, little of which remains. This led to the belief that change is real, and stability illusory, for Heraclitus Everything flows, nothing stands still. He is also famous for saying, No man can cross the river twice. Empedocles was a citizen of Agrigentum, a Greek colony in Sicily, empedocles philosophy is best known for being the origin of the cosmogenic theory of the four classical elements. He maintained that all matter is made up of four elements, water, earth, air, empedocles postulated forces called Love and Strife to explain the attraction and separation of different forms of matter. He was also one of the first people to state the theory that light travels at a finite speed, Anaxagoras of Clazomenae regarded material substance as an infinite multitude of imperishable primary elements, referring all generation and disappearance to mixture and separation respectively. All substance is ordered by a force, the cosmic mind. Archelaus was a Greek philosopher of the 5th century BCE, born probably in Athens and he was a pupil of Anaxagoras, and is said by Ion of Chios to have been the teacher of Socrates. Some argue that this is only an attempt to connect Socrates with the Ionian School. There is similar difference of opinion as regards the statement that Archelaus formulated certain ethical doctrines, in general, he followed Anaxagoras, but in his cosmology he went back to the earlier Ionians

Milesian school
–
The Milesian school was a school of thought founded in the 6th century BC. The ideas associated with it are exemplified by three philosophers from the Ionian town of Miletus, on the Aegean coast of Asia Minor, Thales, Anaximander, and Anaximenes. They introduced new opinions contrary to the belief of how the world was organized. The Milesians conceived of nature in terms of methodologically observable entities and these philosophers defined all things by their quintessential substance of which the world was formed and which was the source of everything. Thales thought it to be water, but as it was impossible to explain some things as being composed of this element, Anaximander chose an unobserved, undefined element, which he called apeiron. Consequently, there must be another entity from which the others originate, the notion of temporal infinity was familiar to the Greek mind in the religious conception of immortality and Anaximanders description was in terms appropriate to this conception. This arche is called eternal and ageless, critics disliked the unspecified nature of the apeiron, which caused Anaximenes to define it as being air, which is a more concrete, yet still subtle, element. Anaximenes held that by its evaporation and condensation, air can change into other elements or substances such as fire, wind, clouds, water, however, our modern concept of energy is much more similar to Anaximanders apeiron. The differences between the three philosophers was not limited to the nature of matter, each of them conceived of the universe differently. Thales held that the world was floating in water, for Anaximenes, the sun and the moon were flat disks traveling around a heavenly canopy, on which the stars were fixed.

Astronomy
–
Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets, while the phenomena include supernovae explosions, gamma ray bursts, more generally, all astronomical phenomena that originate outside Earths atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole, Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, during the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the results and observations being used to confirm theoretical results. Astronomy is one of the few sciences where amateurs can play an active role, especially in the discovery. Amateur astronomers have made and contributed to many important astronomical discoveries, Astronomy means law of the stars. Astronomy should not be confused with astrology, the system which claims that human affairs are correlated with the positions of celestial objects. Although the two share a common origin, they are now entirely distinct. Generally, either the term astronomy or astrophysics may be used to refer to this subject, however, since most modern astronomical research deals with subjects related to physics, modern astronomy could actually be called astrophysics. Few fields, such as astrometry, are purely astronomy rather than also astrophysics, some titles of the leading scientific journals in this field includeThe Astronomical Journal, The Astrophysical Journal and Astronomy and Astrophysics. In early times, astronomy only comprised the observation and predictions of the motions of objects visible to the naked eye, in some locations, early cultures assembled massive artifacts that possibly had some astronomical purpose. Before tools such as the telescope were invented, early study of the stars was conducted using the naked eye, most of early astronomy actually consisted of mapping the positions of the stars and planets, a science now referred to as astrometry. From these observations, early ideas about the motions of the planets were formed, and the nature of the Sun, Moon, the Earth was believed to be the center of the Universe with the Sun, the Moon and the stars rotating around it. This is known as the model of the Universe, or the Ptolemaic system. The Babylonians discovered that lunar eclipses recurred in a cycle known as a saros

Geometry
–
Geometry is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer, Geometry arose independently in a number of early cultures as a practical way for dealing with lengths, areas, and volumes. Geometry began to see elements of mathematical science emerging in the West as early as the 6th century BC. By the 3rd century BC, geometry was put into a form by Euclid, whose treatment, Euclids Elements. Geometry arose independently in India, with texts providing rules for geometric constructions appearing as early as the 3rd century BC, islamic scientists preserved Greek ideas and expanded on them during the Middle Ages. By the early 17th century, geometry had been put on a solid footing by mathematicians such as René Descartes. Since then, and into modern times, geometry has expanded into non-Euclidean geometry and manifolds, while geometry has evolved significantly throughout the years, there are some general concepts that are more or less fundamental to geometry. These include the concepts of points, lines, planes, surfaces, angles, contemporary geometry has many subfields, Euclidean geometry is geometry in its classical sense. The mandatory educational curriculum of the majority of nations includes the study of points, lines, planes, angles, triangles, congruence, similarity, solid figures, circles, Euclidean geometry also has applications in computer science, crystallography, and various branches of modern mathematics. Differential geometry uses techniques of calculus and linear algebra to problems in geometry. It has applications in physics, including in general relativity, topology is the field concerned with the properties of geometric objects that are unchanged by continuous mappings. In practice, this often means dealing with large-scale properties of spaces, convex geometry investigates convex shapes in the Euclidean space and its more abstract analogues, often using techniques of real analysis. It has close connections to convex analysis, optimization and functional analysis, algebraic geometry studies geometry through the use of multivariate polynomials and other algebraic techniques. It has applications in areas, including cryptography and string theory. Discrete geometry is concerned mainly with questions of relative position of simple objects, such as points. It shares many methods and principles with combinatorics, Geometry has applications to many fields, including art, architecture, physics, as well as to other branches of mathematics. The earliest recorded beginnings of geometry can be traced to ancient Mesopotamia, the earliest known texts on geometry are the Egyptian Rhind Papyrus and Moscow Papyrus, the Babylonian clay tablets such as Plimpton 322. For example, the Moscow Papyrus gives a formula for calculating the volume of a truncated pyramid, later clay tablets demonstrate that Babylonian astronomers implemented trapezoid procedures for computing Jupiters position and motion within time-velocity space

Geography
–
Geography is a field of science devoted to the study of the lands, the features, the inhabitants, and the phenomena of Earth. The first person to use the word γεωγραφία was Eratosthenes, Geography is an all-encompassing discipline that seeks an understanding of the Earth and its human and natural complexities—not merely where objects are, but how they have changed and come to be. It is often defined in terms of the two branches of geography and physical geography. Geography has been called the world discipline and the bridge between the human and the physical sciences, Geography is a systematic study of the Earth and its features. Traditionally, geography has been associated with cartography and place names, although many geographers are trained in toponymy and cartology, this is not their main preoccupation. Geographers study the space and the temporal database distribution of phenomena, processes, because space and place affect a variety of topics, such as economics, health, climate, plants and animals, geography is highly interdisciplinary. The interdisciplinary nature of the approach depends on an attentiveness to the relationship between physical and human phenomena and its spatial patterns. Names of places. are not geography. know by heart a whole gazetteer full of them would not, in itself and this is a description of the world—that is Geography. In a word Geography is a Science—a thing not of mere names but of argument and reason, of cause, just as all phenomena exist in time and thus have a history, they also exist in space and have a geography. Geography as a discipline can be split broadly into two main fields, human geography and physical geography. The former largely focuses on the environment and how humans create, view, manage. The latter examines the environment, and how organisms, climate, soil, water. The difference between these led to a third field, environmental geography, which combines physical and human geography. Physical geography focuses on geography as an Earth science and it aims to understand the physical problems and the issues of lithosphere, hydrosphere, atmosphere, pedosphere, and global flora and fauna patterns. Physical geography can be divided into broad categories, including, Human geography is a branch of geography that focuses on the study of patterns. It encompasses the human, political, cultural, social, and it requires an understanding of the traditional aspects of physical and human geography, as well as the ways that human societies conceptualize the environment. Integrated geography has emerged as a bridge between the human and the geography, as a result of the increasing specialisation of the two sub-fields. Examples of areas of research in the environmental geography include, emergency management, environmental management, sustainability, geomatics is concerned with the application of computers to the traditional spatial techniques used in cartography and topography

Evolution
–
Evolution is change in the heritable characteristics of biological populations over successive generations. Evolutionary processes give rise to biodiversity at every level of organisation, including the levels of species, individual organisms. In July 2016, scientists reported identifying a set of 355 genes from the LUCA of all living on Earth. The fossil record includes a progression from early biogenic graphite, to microbial mat fossils, existing patterns of biodiversity have been shaped both by speciation and by extinction. More than 99 percent of all species that lived on Earth are estimated to be extinct. Estimates of Earths current species range from 10 to 14 million, more recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described. In the mid-19th century, Charles Darwin formulated the theory of evolution by natural selection. This teleonomy is the quality whereby the process of natural selection creates and preserves traits that are fitted for the functional roles they perform. The processes by which the changes occur, from one generation to another, are called evolutionary processes or mechanisms, the four most widely recognized evolutionary processes are natural selection, genetic drift, mutation and gene migration. Natural selection and genetic drift sort variation, mutation and gene migration create variation, consequences of selection can include meiotic drive, nonrandom mating and genetic hitchhiking. In the early 20th century the modern evolutionary synthesis integrated classical genetics with Darwins theory of evolution by natural selection through the discipline of population genetics, the importance of natural selection as a cause of evolution was accepted into other branches of biology. Moreover, previously held notions about evolution, such as orthogenesis, evolutionism, evolutionary computation, a sub-field of artificial intelligence, involves the application of Darwinian principles to problems in computer science. The proposal that one type of organism could descend from another type goes back to some of the first pre-Socratic Greek philosophers, such as Anaximander, such proposals survived into Roman times. The poet and philosopher Lucretius followed Empedocles in his masterwork De rerum natura, in contrast to these materialistic views, Aristotelianism considered all natural things as actualisations of fixed natural possibilities, known as forms. This was part of a teleological understanding of nature in which all things have an intended role to play in a divine cosmic order. In the 17th century, the new method of modern science rejected the Aristotelian approach, however, this new approach was slow to take root in the biological sciences, the last bastion of the concept of fixed natural types. The biological classification introduced by Carl Linnaeus in 1735 explicitly recognized the nature of species relationships. Other naturalists of this time speculated on the change of species over time according to natural laws

Thales of Miletus
–
Thales of Miletus was a pre-Socratic Greek/Phoenician philosopher, mathematician and astronomer from Miletus in Asia Minor. He was one of the Seven Sages of Greece, Thales is recognized for breaking from the use of mythology to explain the world and the universe, and instead explaining natural objects and phenomena by theories and hypothesis, i. e. science. Aristotle reported Thales hypothesis that the principle of nature and the nature of matter was a single material substance. In mathematics, Thales used geometry to calculate the heights of pyramids and he is the first known individual to use deductive reasoning applied to geometry, by deriving four corollaries to Thales theorem. He is the first known individual to whom a mathematical discovery has been attributed, the ancient source, Apollodorus of Athens, writing during the 2nd century BCE, thought Thales was born about the year 625 BCE. The dates of Thales life are not exactly known, but are roughly established by a few events mentioned in the sources. According to Herodotus Thales predicted the eclipse of May 28,585 BC. Diogenes Laërtius quotes the chronicle of Apollodorus of Athens as saying that Thales died at the age of 78 during the 58th Olympiad and attributes his death to heat stroke while watching the games. Plutarch had earlier told this version, Solon visited Thales and asked him why he remained single, nevertheless, several years later, anxious for family, he adopted his nephew Cybisthus. Thales involved himself in many activities, taking the role of an innovator, some say that he left no writings, others say that he wrote On the Solstice and On the Equinox. Diogenes Laërtius quotes two letters from Thales, one to Pherecydes of Syros, offering to review his book on religion, Thales identifies the Milesians as Athenian colonists. He was aware of the existence of the lodestone, and was the first to be connected to knowledge of this in history, according to Aristotle, Thales thought lodestones had souls, because iron is attracted to them. According to Hieronymus, historically quoted by Diogenes Laertius, Thales found the height of pyramids by comparison between the lengths of the shadows cast by a person and by the pyramids, several anecdotes suggest Thales was not just a philosopher, but also a businessman. A story, with different versions, recounts how Thales achieved riches from an olive harvest by prediction of the weather, in one version, he bought all the olive presses in Miletus after predicting the weather and a good harvest for a particular year. Thales’ political life had mainly to do with the involvement of the Ionians in the defense of Anatolia against the power of the Persians. In neighbouring Lydia, a king had come to power, Croesus and he had conquered most of the states of coastal Anatolia, including the cities of the Ionians. The story is told in Herodotus, the war endured for five years, but in the sixth an eclipse of the Sun spontaneously halted a battle in progress. It seems that Thales had predicted this solar eclipse, the Seven Sages were most likely already in existence, as Croesus was also heavily influenced by Solon of Athens, another sage

Anaximenes of Miletus
–
Anaximenes of Miletus was an Ancient Greek Pre-Socratic philosopher active in the latter half of the 6th century BC. One of the three Milesian philosophers, he is identified as a friend or student of Anaximander. Anaximenes, like others in his school of thought, practiced material monism and this tendency to identify one specific underlying reality made up of a material thing is what Anaximenes is principally known for today. The choice of air may seem arbitrary, but Anaximenes based his conclusion on naturally observable phenomena in the processes of rarefaction and condensation, when air condenses it becomes visible, as mist and then rain and other forms of precipitation. As the condensed air cools Anaximenes supposed that it went on to form earth, in contrast, water evaporates into air, which ignites and produces flame when further rarefied. Having concluded that everything in the world is composed of air, Anaximenes used his theory to devise a scheme that explains the origins and nature of the earth and the surrounding celestial bodies. Air felted to create the flat disk of the earth, which he said was table-like and behaved like a leaf floating on air. In keeping with the view of celestial bodies as balls of fire in the sky, Anaximenes proposed that the earth let out an exhalation of air that rarefied, ignited. Similarly, he considered the moon and sun to be flat, in his theory, when the sun sets it does not pass under the earth, but is merely obscured by higher parts of the earth as it circles around and becomes more distant. Anaximenes likens the motion of the sun and the celestial bodies around the earth to the way that a cap may be turned around the head. Anaximenes used his observations and reasoning to provide causes for natural phenomena on the earth as well. In either case the earth becomes weakened by its cracks, so that hills collapse and cause earthquakes, lightning is similarly caused by the violent separation of clouds by the wind, creating a bright, fire-like flash. Rainbows, on the hand, are formed when densely compressed air is touched by the rays of the sun. These examples show how Anaximenes, like the other Milesian philosophers and they sought unifying causes for diversely occurring events, rather than treating each one on a case-by-case basis, or attributing them to gods or to a personified nature. The Anaximenes crater on the Moon is named in his honor, the Earlier Presocratics and the Pythagoreans. The Art and Culture of Early Greece, 1100-480 BC, Early Greek Thought, Before the Dawn.

Pythagoras
–
Pythagoras of Samos was an Ionian Greek philosopher, mathematician, and the putative founder of the movement called Pythagoreanism. Most of the information about Pythagoras was written centuries after he lived. He was born on the island of Samos, and travelled, visiting Egypt and Greece, around 530 BC, he moved to Croton, in Magna Graecia, and there established some kind of school or guild. In 520 BC, he returned to Samos, Pythagoras made influential contributions to philosophy and religion in the late 6th century BC. He is often revered as a mathematician and scientist and is best known for the Pythagorean theorem which bears his name. Many of the accomplishments credited to Pythagoras may actually have been accomplishments of his colleagues, some accounts mention that the philosophy associated with Pythagoras was related to mathematics and that numbers were important. It was said that he was the first man to himself a philosopher, or lover of wisdom, and Pythagorean ideas exercised a marked influence on Plato. Burkert states that Aristoxenus and Dicaearchus are the most important accounts, Aristotle had written a separate work On the Pythagoreans, which is no longer extant. However, the Protrepticus possibly contains parts of On the Pythagoreans and his disciples Dicaearchus, Aristoxenus, and Heraclides Ponticus had written on the same subject. These writers, late as they are, were among the best sources from whom Porphyry and Iamblichus drew, while adding some legendary accounts. Herodotus, Isocrates, and other writers agree that Pythagoras was the son of Mnesarchus and born on the Greek island of Samos. His father is said to have been a gem-engraver or a wealthy merchant, a late source gives his mothers name as Pythais. As to the date of his birth, Aristoxenus stated that Pythagoras left Samos in the reign of Polycrates, at the age of 40, around 530 BC he arrived in the Greek colony of Croton in what was then Magna Graecia. There he founded his own school the members of which he engaged to a disciplined. He furthermore aquired some political influence, on Greeks and non-Greeks of the region, following a conflict with the neighbouring colony of Sybaris, internal discord drove most of the Pythagoreans out of Croton. Pythagoras left the city before the outbreak of civil unrest and moved to Metapontum, after his death, his house was transformed into a sanctuary of Demeter, out of veneration for the philosopher, by the local population. In ancient sources there was disagreement and inconsistency about the late life of Pythagoras. His tomb was shown at Metapontum in the time of Cicero, according to Walter Burkert, Most obvious is the contradiction between Aristoxenus and Dicaearchus, regarding the catastrophe that overwhelmed the Pythagorean society

Democritus
–
Democritus was an influential Ancient Greek pre-Socratic philosopher primarily remembered today for his formulation of an atomic theory of the universe. Democritus was born in Abdera, Thrace, around 460 BC, although and his exact contributions are difficult to disentangle from those of his mentor Leucippus, as they are often mentioned together in texts. Largely ignored in ancient Athens, Democritus is said to have been disliked so much by Plato that the latter wished all of his books burned and he was nevertheless well known to his fellow northern-born philosopher Aristotle. Many consider Democritus to be the father of modern science, none of his writings have survived, only fragments are known from his vast body of work. Democritus was said to be born in the city of Abdera in Thrace and he was born in the 80th Olympiad according to Apollodorus of Athens, and although Thrasyllus placed his birth in 470 BC, the later date is probably more likely. John Burnet has argued that the date of 460 is too early since, according to Diogenes Laërtius ix.41 and it was said that Democrituss father was from a noble family and so wealthy that he received Xerxes on his march through Abdera. Democritus spent the inheritance which his father left him on travels into distant countries and he traveled to Asia, and was even said to have reached India and Ethiopia. It is known that he wrote on Babylon and Meroe, he visited Egypt and he himself declared that among his contemporaries none had made greater journeys, seen more countries, and met more scholars than himself. He particularly mentions the Egyptian mathematicians, whose knowledge he praises, theophrastus, too, spoke of him as a man who had seen many countries. During his travels, according to Diogenes Laërtius, he acquainted with the Chaldean magi. Ostanes, one of the magi accompanying Xerxes, was said to have taught him. After returning to his land he occupied himself with natural philosophy. He traveled throughout Greece to acquire a knowledge of its cultures. He mentions many Greek philosophers in his writings, and his wealth enabled him to purchase their writings, Leucippus, the founder of atomism, was the greatest influence upon him. Diogenes Laertius says that he was friends with Hippocrates and he may have been acquainted with Socrates, but Plato does not mention him and Democritus himself is quoted as saying, I came to Athens and no one knew me. Aristotle placed him among the natural philosophers. The many anecdotes about Democritus, especially in Diogenes Laërtius, attest to his disinterest, modesty, and simplicity, one story has him deliberately blinding himself in order to be less disturbed in his pursuits, it may well be true that he lost his sight in old age. He was cheerful, and was ready to see the comical side of life

Ancient Greek astronomy
–
{{Refimprove|date=October 2011 Greek astronomy is written in the Greek language in classical antiquity. Greek astronomy is understood to include the ancient Greek, Hellenistic, Greco-Roman and it is not limited geographically to Greece or to ethnic Greeks, as the Greek language had become the language of scholarship throughout the Hellenistic world following the conquests of Alexander. This phase of Greek astronomy is known as Hellenistic astronomy. During the Hellenistic and Roman periods, much of the Greek and non-Greek astronomers working in the Greek tradition studied at the Musaeum, the development of astronomy by the Greek and Hellenistic astronomers is considered by historians to be a major phase in the history of astronomy. Greek astronomy is characterized from the start by seeking a rational, physical explanation for celestial phenomena, most of the constellations of the northern hemisphere derive from Greek astronomy, as are the names of many stars, asteroids, and planets. It was influenced by Egyptian and especially Babylonian astronomy, in turn, it influenced Indian, Arabic-Islamic, references to identifiable stars and constellations appear in the writings of Homer and Hesiod, the earliest surviving examples of Greek literature. Though neither Homer nor Hesiod set out to write a scientific work, some stars rise and set, others are ever-visible. At certain times of the year, certain stars will rise or set at sunrise or sunset, speculation about the cosmos was common in Pre-Socratic philosophy in the 6th and 5th centuries BC. Anaximander described a cylindrical earth suspended in the center of the cosmos, philolaus the Pythagorean described a cosmos with the stars, planets, Sun, Moon, Earth, and a counter-Earth —ten bodies in all—circling an unseen central fire. Such reports show that Greeks of the 6th and 5th centuries BC were aware of the planets and speculated about the structure of the cosmos. Also, a detailed description about the cosmos, Stars, Sun, Moon and the Earth can be found in the Orphism, which dates back to the end of the 5th century BC. The name planet comes from the Greek term πλανήτης, meaning wanderer, five planets can be seen with the naked eye, Mercury, Venus, Mars, Jupiter, and Saturn, the Greek names being Hermes, Aphrodite, Ares, Zeus and Cronus. Sometimes the luminaries, the Sun and Moon, are added to the list of naked eye planets to make a total of seven, since the planets disappear from time to time when they approach the Sun, careful attention is required to identify all five. Observations of Venus are not straightforward and they eventually came to recognize that both objects were the same planet. Pythagoras is given credit for this realization, in classical Greece, astronomy was a branch of mathematics, astronomers sought to create geometrical models that could imitate the appearances of celestial motions. This tradition began with the Pythagoreans, who placed astronomy among the four mathematical arts, the study of number comprising the four arts was later called the Quadrivium. Although he was not a mathematician, Plato included the quadrivium as the basis for philosophical education in the Republic. He encouraged a younger mathematician, Eudoxus of Cnidus, to develop a system of Greek astronomy, platos main books on cosmology are the Timaeus and the Republic

Martin Heidegger
–
Martin Heidegger was a German philosopher and a seminal thinker in the Continental tradition and philosophical hermeneutics. According to the Internet Encyclopedia of Philosophy, he is acknowledged to be one of the most original. His first and best known book, Being and Time, though unfinished, is one of the philosophical works of the 20th century. Heidegger approached the question through an inquiry into the being that has an understanding of Being, and asks the question about it, namely, Human being, for Heidegger thinking is thinking about things originally discovered in our everyday practical engagements. The consequence of this is that our capacity to think cannot be the most central quality of our being because thinking is a reflecting upon this more original way of discovering the world. Heideggers later work includes criticisms of technologys instrumentalist understanding in the Western tradition as enframing, treating all of Nature as a reserve on call for human purposes. Heidegger was born in rural Meßkirch, Germany, the son of Johanna, raised a Roman Catholic, he was the son of the sexton of the village church that adhered to the First Vatican Council of 1870, which was observed mainly by the poorer class of Meßkirch. Heidegger was short and sinewy, with piercing eyes. He enjoyed outdoor pursuits, being proficient at skiing. In the two following, he worked first as an unsalaried Privatdozent. He served as a soldier during the year of World War I, working behind a desk. During the 1930s, critics of Heideggers espousal of a Nazi-style rhetoric of martial manliness noted the unheroic nature of his service in WWI, in 1923, Heidegger was elected to an extraordinary Professorship in Philosophy at the University of Marburg. His colleagues there included Rudolf Bultmann, Nicolai Hartmann, and Paul Natorp, Heideggers students at Marburg included Hans-Georg Gadamer, Hannah Arendt, Karl Löwith, Gerhard Krüger, Leo Strauss, Jacob Klein, Gunther Anders, and Hans Jonas. Following on from Aristotle, he began to develop in his lectures the main theme of his philosophy, the question of the sense of being. He extended the concept of subject to the dimension of history and concrete existence, which he found prefigured in such Christian thinkers as Saint Paul, Augustine of Hippo, Luther and he also read the works of Dilthey, Husserl, and Max Scheler. In 1927, Heidegger published his main work Sein und Zeit, when Husserl retired as Professor of Philosophy in 1928, Heidegger accepted Freiburgs election to be his successor, in spite of a counter-offer by Marburg. Heidegger remained at Freiburg im Breisgau for the rest of his life, declining a number of later offers and his students at Freiburg included Arendt, Günther Anders, Hans Jonas, Karl Löwith, Charles Malik, Herbert Marcuse and Ernst Nolte. Emmanuel Levinas attended his lecture courses during his stay in Freiburg in 1928, Heidegger was elected rector of the University on 21 April 1933, and joined the National Socialist German Workers Party on 1 May

Greek language
–
Greek is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean. It has the longest documented history of any living language, spanning 34 centuries of written records and its writing system has been the Greek alphabet for the major part of its history, other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic and many other writing systems. Together with the Latin texts and traditions of the Roman world, during antiquity, Greek was a widely spoken lingua franca in the Mediterranean world and many places beyond. It would eventually become the official parlance of the Byzantine Empire, the language is spoken by at least 13.2 million people today in Greece, Cyprus, Italy, Albania, Turkey, and the Greek diaspora. Greek roots are used to coin new words for other languages, Greek. Greek has been spoken in the Balkan peninsula since around the 3rd millennium BC, the earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the worlds oldest recorded living language. Among the Indo-European languages, its date of earliest written attestation is matched only by the now extinct Anatolian languages, the Greek language is conventionally divided into the following periods, Proto-Greek, the unrecorded but assumed last ancestor of all known varieties of Greek. The unity of Proto-Greek would have ended as Hellenic migrants entered the Greek peninsula sometime in the Neolithic era or the Bronze Age, Mycenaean Greek, the language of the Mycenaean civilisation. It is recorded in the Linear B script on tablets dating from the 15th century BC onwards, Ancient Greek, in its various dialects, the language of the Archaic and Classical periods of the ancient Greek civilisation. It was widely known throughout the Roman Empire, after the Roman conquest of Greece, an unofficial bilingualism of Greek and Latin was established in the city of Rome and Koine Greek became a first or second language in the Roman Empire. The origin of Christianity can also be traced through Koine Greek, Medieval Greek, also known as Byzantine Greek, the continuation of Koine Greek in Byzantine Greece, up to the demise of the Byzantine Empire in the 15th century. Much of the written Greek that was used as the language of the Byzantine Empire was an eclectic middle-ground variety based on the tradition of written Koine. Modern Greek, Stemming from Medieval Greek, Modern Greek usages can be traced in the Byzantine period and it is the language used by the modern Greeks, and, apart from Standard Modern Greek, there are several dialects of it. In the modern era, the Greek language entered a state of diglossia, the historical unity and continuing identity between the various stages of the Greek language is often emphasised. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than a foreign language and it is also often stated that the historical changes have been relatively slight compared with some other languages. According to one estimation, Homeric Greek is probably closer to demotic than 12-century Middle English is to modern spoken English, Greek is spoken by about 13 million people, mainly in Greece, Albania and Cyprus, but also worldwide by the large Greek diaspora. Greek is the language of Greece, where it is spoken by almost the entire population

Ancient Greek philosophy
–
Ancient Greek philosophy arose in the 6th century BC and continued throughout the Hellenistic period and the period in which Ancient Greece was part of the Roman Empire. Philosophy was used to sense out of the world in a non-religious way. It dealt with a variety of subjects, including political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric. Many philosophers around the world agree that Greek philosophy has influenced much of Western culture since its inception, alfred North Whitehead once noted, The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato. Clear, unbroken lines of lead from ancient Greek and Hellenistic philosophers to Early Islamic philosophy, the European Renaissance. Some claim that Greek philosophy, in turn, was influenced by the wisdom literature. But they taught themselves to reason, Philosophy as we understand it is a Greek creation. Subsequent philosophic tradition was so influenced by Socrates as presented by Plato that it is conventional to refer to philosophy developed prior to Socrates as pre-Socratic philosophy. The periods following this, up to and after the wars of Alexander the Great, are those of classical Greek, the pre-Socratics were primarily concerned with cosmology, ontology and mathematics. They were distinguished from non-philosophers insofar as they rejected mythological explanations in favor of reasoned discourse, Thales of Miletus, regarded by Aristotle as the first philosopher, held that all things arise from water. It is not because he gave a cosmogony that John Burnet calls him the first man of science, according to tradition, Thales was able to predict an eclipse and taught the Egyptians how to measure the height of the pyramids. He began from the observation that the world seems to consist of opposites, therefore, they cannot truly be opposites but rather must both be manifestations of some underlying unity that is neither. This underlying unity could not be any of the classical elements, for example, water is wet, the opposite of dry, while fire is dry, the opposite of wet. Anaximenes in turn held that the arche was air, although John Burnet argues that by this he meant that it was a transparent mist, the aether. Xenophanes was born in Ionia, where the Milesian school was at its most powerful, Burnet says that Xenophanes was not, however, a scientific man, with many of his naturalistic explanations having no further support than that they render the Homeric gods superfluous or foolish. He has been claimed as an influence on Eleatic philosophy, although that is disputed, and a precursor to Epicurus, a representative of a total break between science and religion. Pythagoras lived at roughly the time that Xenophanes did and, in contrast to the latter. Parmenides of Elea cast his philosophy against those who held it is and is not the same, and all travel in opposite directions, —presumably referring to Heraclitus

Miletus
–
Miletus was an ancient Greek city on the western coast of Anatolia, near the mouth of the Maeander River in ancient Caria. Its ruins are located near the village of Balat in Aydın Province. Before the Persian invasion in the middle of the 6th century BC, Miletus greatest wealth and splendor was reached during the Hellenistic era and later Roman times. Evidence of first settlement at the site has been inaccessible by the rise of sea level. The first available evidence is of the Neolithic, in the early and middle Bronze age the settlement came under Minoan influence. Legend has it that an influx of Cretans occurred displacing the indigenous Leleges, the site was renamed Miletus after a place in Crete. The Late Bronze Age, 13th century BC, saw the arrival of Luwian language speakers from south central Anatolia calling themselves the Carians, later in that century other Greeks arrived. The city at that time rebelled against the Hittite Empire, after the fall of that empire the city was destroyed in the 12th century BC and starting about 1000 BC was resettled extensively by the Ionian Greeks. Legend offers an Ionian foundation event sponsored by a founder named Neleus from the Peloponnesus, the Greek Dark Ages were a time of Ionian settlement and consolidation in an alliance called the Ionian League. The Archaic Period of Greece began with a sudden and brilliant flash of art, Miletus is the birthplace of the Hagia Sophias architect Isidore of Miletus and Thales, a pre-Socratic Greek philosopher in c.624 BC. The ruins appear on maps at 37°31. 8N 27°16. 7E, about 3 km north of Balat and 3 km east of Batıköy in Aydın Province. In antiquity the city possessed a harbour at the entry of a large bay. The harbour of Miletus was additionally protected by the small island of Lade. Over the centuries the gulf silted up with alluvium carried by the Meander River, there is a Great Harbour Monument where, according to the New Testament account, the apostle Paul stopped on his way back to Jerusalem by boat. He met the Ephesian Elders and then headed out to the beach to bid farewell, recorded in the book of Acts 20. During the Pleistocene epoch the Miletus region was submerged in the Aegean Sea and it subsequently emerged slowly, the sea reaching a low level of about 130 meters below present level at about 18,000 BP. The site of Miletus was part of the mainland, a gradual rise brought a level of about 1.75 meters below present at about 5500 BP, creating several karst block islands of limestone, the location of the first settlements at Miletus. At about 1500 BC the karst shifted due to small crustal movements, since then the sea has risen 1.75 m but the peninsula has been surrounded by sediment from the Maeander river and is now land-locked

Ionia
–
Ionia is an ancient region of central coastal Anatolia in present-day Turkey, the region nearest İzmir, which was historically Smyrna. It consisted of the northernmost territories of the Ionian League of Greek settlements, never a unified state, it was named after the Ionian tribe who, in the Archaic Period, settled mainly the shores and islands of the Aegean Sea. Ionian states were identified by tradition and by their use of Eastern Greek and it was bounded by Aeolia to the north, Lydia to the east and Caria to the south. The cities within the region figured large in the strife between the Persian Empire and the Greeks, according to Greek tradition, the cities of Ionia were founded by colonists from the other side of the Aegean. Their settlement was connected with the history of the Ionic people in Attica, which asserts that the colonists were led by Neleus and Androclus, sons of Codrus. So intricate is the coastline that the voyage along its shores was estimated at four times the direct distance. A great part of area was, moreover, occupied by mountains. None of these mountains attains a height of more than 1,200 metres, the geography of Ionia placed it in a strategic position that was both advantageous and disadvantageous. Ionia was always a maritime power founded by a people who made their living by trade in peaceful times, the coast was rocky and the arable land slight. The native Luwians for the most part kept their fields further inland, the coastal cities were placed in defensible positions on islands or headlands situated so as to control inland routes up the rift valleys. The people of those valleys were of different ethnicity, the populations of the cities came from many civilizations in the eastern Mediterranean. Ancient demographics are available only from literary sources, Herodotus states that in Asia the Ionians kept the division into twelve cities that had prevailed in Ionian lands of the north Peloponnese, their former homeland, which became Achaea after they left. These Asian cities were Miletus, Myus, Priene, Ephesus, Colophon, Lebedos, Teos, Erythrae, Clazomenae and Phocaea, together with Samos and Chios. Smyrna, originally an Aeolic colony, was occupied by Ionians from Colophon. These cities do not match those of Achaea, moreover, the Achaea of Herodotus time spoke Doric, but in Homer it is portrayed as being in the kingdom of Mycenae, which most likely spoke Mycenaean Greek, which is not Doric. If the Ionians came from Achaea, they departed during or after the change from East Greek to West Greek there, Mycenaean continued to evolve in the mountainous region of Arcadia. Miletus and some other cities founded earlier by non-Greeks received populations of Mycenaean Greeks probably under the name of Achaeans, the tradition of Ionian colonizers from Achaea suggests that they may have been known by both names even then. In the Indian historic literary texts, the Ionians are referred to as yavanar or yona, in modern Turkish, the people of that region were called yunan and the country that is now Greece is known as Yunanistan

Science
–
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The formal sciences are often excluded as they do not depend on empirical observations, disciplines which use science, like engineering and medicine, may also be considered to be applied sciences. However, during the Islamic Golden Age foundations for the method were laid by Ibn al-Haytham in his Book of Optics. In the 17th and 18th centuries, scientists increasingly sought to formulate knowledge in terms of physical laws, over the course of the 19th century, the word science became increasingly associated with the scientific method itself as a disciplined way to study the natural world. It was during this time that scientific disciplines such as biology, chemistry, Science in a broad sense existed before the modern era and in many historical civilizations. Modern science is distinct in its approach and successful in its results, Science in its original sense was a word for a type of knowledge rather than a specialized word for the pursuit of such knowledge. In particular, it was the type of knowledge which people can communicate to each other, for example, knowledge about the working of natural things was gathered long before recorded history and led to the development of complex abstract thought. This is shown by the construction of calendars, techniques for making poisonous plants edible. For this reason, it is claimed these men were the first philosophers in the strict sense and they were mainly speculators or theorists, particularly interested in astronomy. In contrast, trying to use knowledge of nature to imitate nature was seen by scientists as a more appropriate interest for lower class artisans. A clear-cut distinction between formal and empirical science was made by the pre-Socratic philosopher Parmenides, although his work Peri Physeos is a poem, it may be viewed as an epistemological essay on method in natural science. Parmenides ἐὸν may refer to a system or calculus which can describe nature more precisely than natural languages. Physis may be identical to ἐὸν and he criticized the older type of study of physics as too purely speculative and lacking in self-criticism. He was particularly concerned that some of the early physicists treated nature as if it could be assumed that it had no intelligent order, explaining things merely in terms of motion and matter. The study of things had been the realm of mythology and tradition, however. Aristotle later created a less controversial systematic programme of Socratic philosophy which was teleological and he rejected many of the conclusions of earlier scientists. For example, in his physics, the sun goes around the earth, each thing has a formal cause and final cause and a role in the rational cosmic order. Motion and change is described as the actualization of potentials already in things, while the Socratics insisted that philosophy should be used to consider the practical question of the best way to live for a human being, they did not argue for any other types of applied science
21.
Cosmogony
–
Cosmogony is any model concerning the origin of either the cosmos or universe. Developing a complete theoretical model has implications in both the philosophy of science and epistemology, the word comes from the Koine Greek κοσμογονία and the root of γίνομαι / γέγονα. The Big Bang theory is the cosmological model of the early development of the universe. The most commonly held view is that the universe was once a gravitational singularity, however, while this expansion is well-modeled by the Big Bang theory, the origins of the singularity remain as one of the unsolved problems in physics. Cosmologist and science communicator Sean M, one cosmogonical view sees time as fundamental and even eternal, The universe could have contained the singularity because the universe evolved or changed from a prior state. The other view, held by proponents like Stephen Hawking, says there was no change through time because time itself emerged along with this universe. Thus, it unclear what combination of stuff, space, or time emerged with the singularity. One problem in cosmogony is that there is no theoretical model that explains the earliest moments of the universes existence because of a lack of a testable theory of quantum gravity. Researchers in string theory and its extensions, and of quantum cosmology, have nevertheless proposed solutions of the type just discussed. Another issue facing the field of physics is a need for more expensive. Cosmogony can be distinguished from cosmology, which studies the universe at large and throughout its existence, there is some ambiguity between the two terms. For example, the argument from theology regarding the existence of God is technically an appeal to cosmogonical rather than cosmological ideas. In practice, there is a distinction between cosmological and cosmogonical ideas. Physical cosmology is the science that attempts to explain all observations relevant to the development, cosmogonists have only tentative theories for the early stages of the universe and its beginning. Therefore, significant technological and conceptual advances would be needed to propose a scientific test for cosmogonical theories, proposed theoretical scenarios differ radically, and include string theory and M-theory, the Hartle–Hawking initial state, string landscape, brane inflation, the Big Bang, and the ekpyrotic universe. Some of these models are compatible, whereas others are not

Philosophy
–
Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. The term was coined by Pythagoras. Philosophical methods include questioning, critical discussion, rational argument and systematic presentation, classic philosophical questions include, Is it possible to know anything and to prove it. However, philosophers might also pose more practical and concrete questions such as, is it better to be just or unjust. Historically, philosophy encompassed any body of knowledge, from the time of Ancient Greek philosopher Aristotle to the 19th century, natural philosophy encompassed astronomy, medicine and physics. For example, Newtons 1687 Mathematical Principles of Natural Philosophy later became classified as a book of physics, in the 19th century, the growth of modern research universities led academic philosophy and other disciplines to professionalize and specialize. In the modern era, some investigations that were part of philosophy became separate academic disciplines, including psychology, sociology. Other investigations closely related to art, science, politics, or other pursuits remained part of philosophy, for example, is beauty objective or subjective. Are there many scientific methods or just one, is political utopia a hopeful dream or hopeless fantasy. Major sub-fields of academic philosophy include metaphysics, epistemology, ethics, aesthetics, political philosophy, logic, philosophy of science, since the 20th century, professional philosophers contribute to society primarily as professors, researchers and writers. Traditionally, the term referred to any body of knowledge. In this sense, philosophy is related to religion, mathematics, natural science, education. This division is not obsolete but has changed, Natural philosophy has split into the various natural sciences, especially astronomy, physics, chemistry, biology and cosmology. Moral philosophy has birthed the social sciences, but still includes value theory, metaphysical philosophy has birthed formal sciences such as logic, mathematics and philosophy of science, but still includes epistemology, cosmology and others. Many philosophical debates that began in ancient times are still debated today, colin McGinn and others claim that no philosophical progress has occurred during that interval. Chalmers and others, by contrast, see progress in philosophy similar to that in science, in one general sense, philosophy is associated with wisdom, intellectual culture and a search for knowledge. In that sense, all cultures and literate societies ask philosophical questions such as how are we to live, a broad and impartial conception of philosophy then, finds a reasoned inquiry into such matters as reality, morality and life in all world civilizations. Socrates was an influential philosopher, who insisted that he possessed no wisdom but was a pursuer of wisdom

Gnomon
–
A gnomon is the part of a sundial that casts a shadow. The term has come to be used for a variety of purposes in mathematics, a painted stick from 2300 BCE found in China is the oldest known gnomon. Anaximander is credited with introducing this Babylonian instrument to the Greeks, oenopides used the phrase drawn gnomon-wise to describe a line drawn perpendicular to another. Later, the term was used for an L-shaped instrument like a steel square used to right angles. This shape may explain its use to describe a shape formed by cutting a square from a larger one. Euclid extended the term to the figure formed by removing a similar parallelogram from a corner of a larger parallelogram. Indeed, the gnomon is the increment between two successive figurate numbers, including square and triangular numbers, hero of Alexandria defined a gnomon as that which, when added to an entity, makes a new entity similar to the starting entity. In this sense Theon of Smyrna used it to describe a number added to a polygonal number produces the next one of the same type. The most common use in this sense is an odd integer especially when seen as a number between square numbers. Perforated gnomons projecting an image of the sun were described in the Chinese Zhoubi Suanjing writings. The location of the circle can be measured to tell the time of day. In Arab and European cultures its invention was later attributed to Egyptian astronomer. With markings on the floor it tells the time of each midday as well as the date of the summer solstice. Italian mathematician, engineer, astronomer and geographer Leonardo Ximenes reconstructed the gnomon according to his new measurements in 1756, in the northern hemisphere, the shadow-casting edge of a sundial gnomon is normally oriented so that it points north and is parallel to the rotation axis of the Earth. That is, it is inclined to the horizontal at an angle equals the latitude of the sundials location. At present, such a gnomon should thus point almost precisely at Polaris, on some sundials, the gnomon is vertical. These were usually used in times for observing the altitude of the Sun. The style is the part of the gnomon that casts the shadow and this can change as the sun moves

Politics
–
Politics is the process of making decisions applying to all members of each group. More narrowly, it refers to achieving and exercising positions of governance — organized control over a human community, furthermore, politics is the study or practice of the distribution of power and resources within a given community as well as the interrelationship between communities. It is very often said that politics is about power, a political system is a framework which defines acceptable political methods within a given society. History of political thought can be traced back to antiquity, with seminal works such as Platos Republic, Aristotles Politics. Formal Politics refers to the operation of a system of government and publicly defined institutions. Political parties, public policy or discussions about war and foreign affairs would fall under the category of Formal Politics, many people view formal politics as something outside of themselves, but that can still affect their daily lives. Semi-formal Politics is Politics in government associations such as neighborhood associations, informal Politics is understood as forming alliances, exercising power and protecting and advancing particular ideas or goals. Generally, this includes anything affecting ones daily life, such as the way an office or household is managed, informal Politics is typically understood as everyday politics, hence the idea that politics is everywhere. The word comes from the same Greek word from which the title of Aristotles book Politics also derives, the book title was rendered in Early Modern English in the mid-15th century as Polettiques, it became politics in Modern English. The history of politics is reflected in the origin, development, the origin of the state is to be found in the development of the art of warfare. Historically speaking, all communities of the modern type owe their existence to successful warfare. Kings, emperors and other types of monarchs in many countries including China, of the institutions that ruled states, that of kingship stood at the forefront until the French Revolution put an end to the divine right of kings. Nevertheless, the monarchy is among the political institutions, dating as early as 2100 BC in Sumeria to the 21st century AD British Monarchy. Kingship becomes an institution through the institution of Hereditary monarchy, the king often, even in absolute monarchies, ruled his kingdom with the aid of an elite group of advisors, a council without which he could not maintain power. As these advisors and others outside the monarchy negotiated for power, constitutional monarchies emerged, long before the council became a bulwark of democracy, it rendered invaluable aid to the institution of kingship by, Preserving the institution of kingship through heredity. Preserving the traditions of the social order, being able to withstand criticism as an impersonal authority. Being able to manage a greater deal of knowledge and action than an individual such as the king. The greatest of the subordinates, the earls and dukes in England and Scotland

Raphael
–
Raffaello Sanzio da Urbino, known as Raphael, was an Italian painter and architect of the High Renaissance. His work is admired for its clarity of form, ease of composition, together with Michelangelo and Leonardo da Vinci, he forms the traditional trinity of great masters of that period. Raphael was enormously productive, running a large workshop and, despite his death at 37. Many of his works are found in the Vatican Palace, where the frescoed Raphael Rooms were the central, the best known work is The School of Athens in the Vatican Stanza della Segnatura. After his early years in Rome much of his work was executed by his workshop from his drawings and he was extremely influential in his lifetime, though outside Rome his work was mostly known from his collaborative printmaking. Raphael was born in the small but artistically significant central Italian city of Urbino in the Marche region and his poem to Federico shows him as keen to show awareness of the most advanced North Italian painters, and Early Netherlandish artists as well. In the very court of Urbino he was probably more integrated into the central circle of the ruling family than most court painters. Under them, the court continued as a centre for literary culture, growing up in the circle of this small court gave Raphael the excellent manners and social skills stressed by Vasari. Castiglione moved to Urbino in 1504, when Raphael was no longer based there but frequently visited, Raphael mixed easily in the highest circles throughout his life, one of the factors that tended to give a misleading impression of effortlessness to his career. He did not receive a humanistic education however, it is unclear how easily he read Latin. His mother Màgia died in 1491 when Raphael was eight, followed on August 1,1494 by his father, Raphael was thus orphaned at eleven, his formal guardian became his only paternal uncle Bartolomeo, a priest, who subsequently engaged in litigation with his stepmother. He probably continued to live with his stepmother when not staying as an apprentice with a master and he had already shown talent, according to Vasari, who says that Raphael had been a great help to his father. A self-portrait drawing from his teenage years shows his precocity and his fathers workshop continued and, probably together with his stepmother, Raphael evidently played a part in managing it from a very early age. In Urbino, he came into contact with the works of Paolo Uccello, previously the court painter, and Luca Signorelli, according to Vasari, his father placed him in the workshop of the Umbrian master Pietro Perugino as an apprentice despite the tears of his mother. The evidence of an apprenticeship comes only from Vasari and another source, an alternative theory is that he received at least some training from Timoteo Viti, who acted as court painter in Urbino from 1495. An excess of resin in the varnish often causes cracking of areas of paint in the works of both masters, the Perugino workshop was active in both Perugia and Florence, perhaps maintaining two permanent branches. Raphael is described as a master, that is to say fully trained and his first documented work was the Baronci altarpiece for the church of Saint Nicholas of Tolentino in Città di Castello, a town halfway between Perugia and Urbino. Evangelista da Pian di Meleto, who had worked for his father, was named in the commission

The School of Athens
–
The School of Athens is one of the most famous frescoes by the Italian Renaissance artist Raphael. It was painted between 1509 and 1511 as a part of Raphaels commission to decorate the rooms now known as the Stanze di Raffaello, the picture has long been seen as Raphaels masterpiece and the perfect embodiment of the classical spirit of the Renaissance. The School of Athens is one of a group of four main frescoes on the walls of the Stanza that depict distinct branches of knowledge, accordingly, the figures on the walls below exemplify Philosophy, Poetry, Theology, and Law. The traditional title is not Raphaels, indeed, Plato and Aristotle appear to be the central figures in the scene. However, all the philosophers depicted sought knowledge of first causes, many lived before Plato and Aristotle, and hardly a third were Athenians. The architecture contains Roman elements, but the general semi-circular setting having Plato, compounding the problem, Raphael had to invent a system of iconography to allude to various figures for whom there were no traditional visual types. For example, while the Socrates figure is immediately recognizable from Classical busts, aside from the identities of the figures depicted, many aspects of the fresco have been variously interpreted, but few such interpretations are unanimously accepted among scholars. The popular idea that the gestures of Plato and Aristotle are kinds of pointing is very likely. Aristotle, with his four-elements theory, held that all change on Earth was owing to motions of the heavens, in the painting Aristotle carries his Ethics, which he denied could be reduced to a mathematical science. Finally, according to Vasari, the scene includes Raphael himself, however, as Heinrich Wölfflin observed, it is quite wrong to attempt interpretations of the School of Athens as an esoteric treatise. The all-important thing was the motive which expressed a physical or spiritual state. An interpretation of the fresco relating to hidden symmetries of the figures, the identities of some of the philosophers in the picture, such as Plato or Aristotle, are certain. Beyond that, identifications of Raphaels figures have always been hypothetical, to complicate matters, beginning from Vasaris efforts, some have received multiple identifications, not only as ancients but also as figures contemporary with Raphael. Vasari mentions portraits of the young Federico II Gonzaga, Duke of Mantua, leaning over Bramante with his hands raised near the bottom right and he was writing over 40 years after the painting, and never knew Raphael, but no doubt reflects what was believed in his time. Many other popular identifications of portraits are very dubious, luitpold Dussler counts among those who can be identified with some certainty, Plato, Aristotle, Socrates, Pythagoras, Euclid, Ptolemy, Zoroaster, Raphael, Sodoma and Diogenes. Other identifications he holds to be more or less speculative, both figures hold modern, bound copies of their books in their left hands, while gesturing with their right. Plato holds Timaeus, Aristotle his Nicomachean Ethics, Plato is depicted as old, grey, wise-looking, and bare-foot. By contrast Aristotle, slightly ahead of him, is in manhood, handsome, well-shod and dressed with gold

Olympiad
–
An Olympiad is a period of four years associated with the Olympic Games of the Ancient Greeks. During the Hellenistic period, beginning with Ephorus, it was used as a calendar epoch, by this reckoning, the first Olympiad lasted from the summer of 776 BC to that of 772 BC. By extrapolation to the Gregorian calendar, the 1st year of the 699th Olympiad begins in mid-summer 2017, a modern Olympiad refers to a four-year period beginning January 1 of a year in which the Summer Olympics are due to occur. The first modern Olympiad began in 1896, the second in 1900, an Olympiad was a period of four years. Example, Olympiad 140, year 1 = 220/219 BC, year 2 = 219/218 BC, year 3 = 218/217 BC, the first to do so consistently was Timaeus of Tauromenium in the third century BC. In the 2nd century AD, Phlegon of Tralles summarised the events of each Olympiad in a book called Olympiads, christian chroniclers continued to use this Greek system of dating as a way of synchronising biblical events with Greek and Roman history. In the 3rd century AD, Sextus Julius Africanus compiled a list of Olympic victors up to 217 BC, early historians sometimes used the names of Olympic victors as a method of dating events to a specific year. For instance, Thucydides says in his account of the year 428 BC and it was in this year that king Xerxes made his campaign against Greece. An Olympiad started with the games, which were held at the beginning of the Olympic new year, though the games were held without interruption, on more than one occasion they were held by others than the Eleians. The Eleians declared such games Anolympiads, but it is assumed the winners were nevertheless recorded, during the 3rd century AD, records of the games are so scanty that historians are not certain whether after 261 they were still held every four years. During the early years of the Olympiad, any physical benefit deriving from a sport was banned, some winners were recorded though, until the last Olympiad of 393AD. In 394, Roman Emperor Theodosius I outlawed the games at Olympia as pagan, though it would have been possible to continue the reckoning by just counting four-year periods, by the middle of the 5th century AD reckoning by Olympiads had become disused. For the modern Olympics the term was used to indicate the games themselves. The modern Olympiad is a period of four consecutive years, beginning on the first of January of the first year. The Olympiads are numbered consecutively from the first Games of the Olympiad celebrated in Athens in 1896, the XXXI Olympiad began on January 1,2016 and will end on December 31,2019. The Summer Olympics are more correctly referred to as the Games of the Olympiad, for example, The first Winter Games, in 1924, were not designated as Winter Games of the VIII Olympiad, but as the I Winter Olympic Games. The 1936 Summer Games were the Games of the XI Olympiad, after the 1940 and 1944 Summer Games were canceled due to World War II, the Games resumed in 1948 as the Games of the XIV Olympiad. However, the 1936 Winter Games were the IV Winter Olympic Games, indeed, at least one IOC-published article has applied this nomenclature as well

Byzantine Empire
–
It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, several signal events from the 4th to 6th centuries mark the period of transition during which the Roman Empires Greek East and Latin West divided. Constantine I reorganised the empire, made Constantinople the new capital, under Theodosius I, Christianity became the Empires official state religion and other religious practices were proscribed. Finally, under the reign of Heraclius, the Empires military, the borders of the Empire evolved significantly over its existence, as it went through several cycles of decline and recovery. During the reign of Maurice, the Empires eastern frontier was expanded, in a matter of years the Empire lost its richest provinces, Egypt and Syria, to the Arabs. This battle opened the way for the Turks to settle in Anatolia, the Empire recovered again during the Komnenian restoration, such that by the 12th century Constantinople was the largest and wealthiest European city. Despite the eventual recovery of Constantinople in 1261, the Byzantine Empire remained only one of several small states in the area for the final two centuries of its existence. Its remaining territories were annexed by the Ottomans over the 15th century. The Fall of Constantinople to the Ottoman Empire in 1453 finally ended the Byzantine Empire, the term comes from Byzantium, the name of the city of Constantinople before it became Constantines capital. This older name of the city would rarely be used from this point onward except in historical or poetic contexts. The publication in 1648 of the Byzantine du Louvre, and in 1680 of Du Canges Historia Byzantina further popularised the use of Byzantine among French authors, however, it was not until the mid-19th century that the term came into general use in the Western world. The Byzantine Empire was known to its inhabitants as the Roman Empire, the Empire of the Romans, Romania, the Roman Republic, Graikia, and also as Rhōmais. The inhabitants called themselves Romaioi and Graikoi, and even as late as the 19th century Greeks typically referred to modern Greek as Romaika and Graikika. The authority of the Byzantine emperor as the legitimate Roman emperor was challenged by the coronation of Charlemagne as Imperator Augustus by Pope Leo III in the year 800. No such distinction existed in the Islamic and Slavic worlds, where the Empire was more seen as the continuation of the Roman Empire. In the Islamic world, the Roman Empire was known primarily as Rûm, the Roman army succeeded in conquering many territories covering the entire Mediterranean region and coastal regions in southwestern Europe and north Africa. These territories were home to different cultural groups, both urban populations and rural populations. The West also suffered heavily from the instability of the 3rd century AD

Rhetoric
–
Rhetoric is the art of discourse, wherein a writer or speaker strives to inform, persuade or motivate particular audiences in specific situations. As a subject of study and a productive civic practice. Its best known definition comes from Aristotle, who considers it a counterpart of both logic and politics, and calls it the faculty of observing in any case the available means of persuasion. The five canons of rhetoric, which trace the traditional tasks in designing a persuasive speech, were first codified in classical Rome, invention, arrangement, style, memory, along with grammar and logic, rhetoric is one of the three ancient arts of discourse. From Ancient Greece to the late 19th century, it was a part of Western education. Scholars have debated the scope of rhetoric since ancient times, although some have limited rhetoric to the specific realm of political discourse, many modern scholars liberate it to encompass every aspect of culture. Contemporary studies of rhetoric address a diverse range of domains than was the case in ancient times. Many contemporary approaches treat rhetoric as human communication that includes purposeful, Public relations, lobbying, law, marketing, professional and technical writing, and advertising are modern professions that employ rhetorical practitioners. Because the ancient Greeks highly valued public political participation, rhetoric emerged as a tool to influence politics. Consequently, rhetoric remains associated with its political origins, however, even the original instructors of Western speech—the Sophists—disputed this limited view of rhetoric. According to the Sophists, such as Gorgias, a successful rhetorician could speak convincingly on any topic and this method suggested rhetoric could be a means of communicating any expertise, not just politics. In his Encomium to Helen, Gorgias even applied rhetoric to fiction by seeking for his own pleasure to prove the blamelessness of the mythical Helen of Troy in starting the Trojan War. Looking to another key rhetorical theorist, Plato defined the scope of rhetoric according to his opinions of the art. He criticized the Sophists for using rhetoric as a means of deceit instead of discovering truth, in Gorgias, one of his Socratic Dialogues, Plato defines rhetoric as the persuasion of ignorant masses within the courts and assemblies. Rhetoric, in Platos opinion, is merely a form of flattery and functions similarly to cookery, thus, Plato considered any speech of lengthy prose aimed at flattery as within the scope of rhetoric. Aristotle both redeemed rhetoric from his teacher and narrowed its focus by defining three genres of rhetoric—deliberative, forensic or judicial, and epideictic, when one considers that rhetoric included torture, it is clear that rhetoric cannot be viewed only in academic terms. However, the enthymeme based upon logic was viewed as the basis of rhetoric, however, since the time of Aristotle, logic has changed. For example, Modal logic has undergone a major development that also modifies rhetoric, yet, Aristotle also outlined generic constraints that focused the rhetorical art squarely within the domain of public political practice

Plato
–
Plato was a philosopher in Classical Greece and the founder of the Academy in Athens, the first institution of higher learning in the Western world. He is widely considered the most pivotal figure in the development of philosophy, unlike nearly all of his philosophical contemporaries, Platos entire work is believed to have survived intact for over 2,400 years. Along with his teacher, Socrates, and his most famous student, Aristotle, Plato laid the foundations of Western philosophy. Alfred North Whitehead once noted, the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato. In addition to being a figure for Western science, philosophy. Friedrich Nietzsche, amongst other scholars, called Christianity, Platonism for the people, Plato was the innovator of the written dialogue and dialectic forms in philosophy, which originate with him. He was not the first thinker or writer to whom the word “philosopher” should be applied, few other authors in the history of Western philosophy approximate him in depth and range, perhaps only Aristotle, Aquinas and Kant would be generally agreed to be of the same rank. Due to a lack of surviving accounts, little is known about Platos early life, the philosopher came from one of the wealthiest and most politically active families in Athens. Ancient sources describe him as a bright though modest boy who excelled in his studies, the exact time and place of Platos birth are unknown, but it is certain that he belonged to an aristocratic and influential family. Based on ancient sources, most modern scholars believe that he was born in Athens or Aegina between 429 and 423 BCE. According to a tradition, reported by Diogenes Laertius, Ariston traced his descent from the king of Athens, Codrus. Platos mother was Perictione, whose family boasted of a relationship with the famous Athenian lawmaker, besides Plato himself, Ariston and Perictione had three other children, these were two sons, Adeimantus and Glaucon, and a daughter Potone, the mother of Speusippus. The brothers Adeimantus and Glaucon are mentioned in the Republic as sons of Ariston, and presumably brothers of Plato, but in a scenario in the Memorabilia, Xenophon confused the issue by presenting a Glaucon much younger than Plato. Then, at twenty-eight, Hermodorus says, went to Euclides in Megara, as Debra Nails argues, The text itself gives no reason to infer that Plato left immediately for Megara and implies the very opposite. Thus, Nails dates Platos birth to 424/423, another legend related that, when Plato was an infant, bees settled on his lips while he was sleeping, an augury of the sweetness of style in which he would discourse about philosophy. Ariston appears to have died in Platos childhood, although the dating of his death is difficult. Perictione then married Pyrilampes, her mothers brother, who had served many times as an ambassador to the Persian court and was a friend of Pericles, Pyrilampes had a son from a previous marriage, Demus, who was famous for his beauty. Perictione gave birth to Pyrilampes second son, Antiphon, the half-brother of Plato and these and other references suggest a considerable amount of family pride and enable us to reconstruct Platos family tree

Aristotle
–
Aristotle was an ancient Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece. His father, Nicomachus, died when Aristotle was a child, at seventeen or eighteen years of age, he joined Platos Academy in Athens and remained there until the age of thirty-seven. Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, teaching Alexander the Great gave Aristotle many opportunities and an abundance of supplies. He established a library in the Lyceum which aided in the production of many of his hundreds of books and he believed all peoples concepts and all of their knowledge was ultimately based on perception. Aristotles views on natural sciences represent the groundwork underlying many of his works, Aristotles views on physical science profoundly shaped medieval scholarship. Their influence extended from Late Antiquity and the Early Middle Ages into the Renaissance, some of Aristotles zoological observations, such as on the hectocotyl arm of the octopus, were not confirmed or refuted until the 19th century. His works contain the earliest known study of logic, which was incorporated in the late 19th century into modern formal logic. Aristotle was well known among medieval Muslim intellectuals and revered as The First Teacher and his ethics, though always influential, gained renewed interest with the modern advent of virtue ethics. All aspects of Aristotles philosophy continue to be the object of academic study today. Though Aristotle wrote many elegant treatises and dialogues – Cicero described his style as a river of gold – it is thought that only around a third of his original output has survived. Aristotle, whose means the best purpose, was born in 384 BC in Stagira, Chalcidice. His father Nicomachus was the physician to King Amyntas of Macedon. Aristotle was orphaned at a young age, although there is little information on Aristotles childhood, he probably spent some time within the Macedonian palace, making his first connections with the Macedonian monarchy. At the age of seventeen or eighteen, Aristotle moved to Athens to continue his education at Platos Academy and he remained there for nearly twenty years before leaving Athens in 348/47 BC. Aristotle then accompanied Xenocrates to the court of his friend Hermias of Atarneus in Asia Minor, there, he traveled with Theophrastus to the island of Lesbos, where together they researched the botany and zoology of the island. Aristotle married Pythias, either Hermiass adoptive daughter or niece and she bore him a daughter, whom they also named Pythias. Soon after Hermias death, Aristotle was invited by Philip II of Macedon to become the tutor to his son Alexander in 343 BC, Aristotle was appointed as the head of the royal academy of Macedon. During that time he gave not only to Alexander

Theophrastus
–
Theophrastus, a Greek native of Eresos in Lesbos, was the successor to Aristotle in the Peripatetic school. He came to Athens at an age and initially studied in Platos school. After Platos death, he attached himself to Aristotle who took to Theophrastus his writings, when Aristotle fled Athens, Theophrastus took over as at the Lyceum. Theophrastus presided over the Peripatetic school for years, during which time the school flourished greatly. He is often considered the father of botany for his works on plants, after his death, the Athenians honoured him with a public funeral. His successor as head of the school was Strato of Lampsacus, the interests of Theophrastus were wide ranging, extending from biology and physics to ethics and metaphysics. His two surviving works, Enquiry into Plants and On the Causes of Plants, were an important influence on Renaissance science. There are also surviving works On Moral Characters, On Sensation, On Stones, in philosophy, he studied grammar and language and continued Aristotles work on logic. He also regarded space as the arrangement and position of bodies, time as an accident of motion. In ethics, he regarded happiness as depending on external influences as well as on virtue and he was a native of Eresos in Lesbos. His given name was Tyrtamus, but he became known by the nickname Theophrastus, given to him, it is said. After receiving instruction in philosophy in Lesbos from one Alcippus, he moved to Athens and he became friends with Aristotle, and when Plato died Theophrastus may have joined Aristotle in his self-imposed exile from Athens. When Aristotle moved to Mytilene on Lesbos in 345/4, it is likely that he did so at the urging of Theophrastus. It seems that it was on Lesbos that Aristotle and Theophrastus began their research into science, with Aristotle studying animals. Theophrastus probably accompanied Aristotle to Macedonia when Aristotle was appointed tutor to Alexander the Great in 343/2, around 335 BC, Theophrastus moved with Aristotle to Athens where Aristotle began teaching in the Lyceum. Aristotle in his will made him guardian of his children, including Nicomachus with whom he was close, Aristotle likewise bequeathed to him his library and the originals of his works, and designated him as his successor at the Lyceum. Eudemus of Rhodes also had claims to this position. Theophrastus presided over the Peripatetic school for years, and died at the age of eighty-five according to Diogenes

Ancient Rome
–
In its many centuries of existence, the Roman state evolved from a monarchy to a classical republic and then to an increasingly autocratic empire. Through conquest and assimilation, it came to dominate the Mediterranean region and then Western Europe, Asia Minor, North Africa and it is often grouped into classical antiquity together with ancient Greece, and their similar cultures and societies are known as the Greco-Roman world. Ancient Roman civilisation has contributed to modern government, law, politics, engineering, art, literature, architecture, technology, warfare, religion, language and society. Rome professionalised and expanded its military and created a system of government called res publica, the inspiration for modern republics such as the United States and France. By the end of the Republic, Rome had conquered the lands around the Mediterranean and beyond, its domain extended from the Atlantic to Arabia, the Roman Empire emerged with the end of the Republic and the dictatorship of Augustus Caesar. 721 years of Roman-Persian Wars started in 92 BC with their first war against Parthia and it would become the longest conflict in human history, and have major lasting effects and consequences for both empires. Under Trajan, the Empire reached its territorial peak, Republican mores and traditions started to decline during the imperial period, with civil wars becoming a prelude common to the rise of a new emperor. Splinter states, such as the Palmyrene Empire, would divide the Empire during the crisis of the 3rd century. Plagued by internal instability and attacked by various migrating peoples, the part of the empire broke up into independent kingdoms in the 5th century. This splintering is a landmark historians use to divide the ancient period of history from the pre-medieval Dark Ages of Europe. King Numitor was deposed from his throne by his brother, Amulius, while Numitors daughter, Rhea Silvia, because Rhea Silvia was raped and impregnated by Mars, the Roman god of war, the twins were considered half-divine. The new king, Amulius, feared Romulus and Remus would take back the throne, a she-wolf saved and raised them, and when they were old enough, they returned the throne of Alba Longa to Numitor. Romulus became the source of the citys name, in order to attract people to the city, Rome became a sanctuary for the indigent, exiled, and unwanted. This caused a problem for Rome, which had a large workforce but was bereft of women, Romulus traveled to the neighboring towns and tribes and attempted to secure marriage rights, but as Rome was so full of undesirables they all refused. Legend says that the Latins invited the Sabines to a festival and stole their unmarried maidens, leading to the integration of the Latins, after a long time in rough seas, they landed at the banks of the Tiber River. Not long after they landed, the men wanted to take to the sea again, one woman, named Roma, suggested that the women burn the ships out at sea to prevent them from leaving. At first, the men were angry with Roma, but they realized that they were in the ideal place to settle. They named the settlement after the woman who torched their ships, the Roman poet Virgil recounted this legend in his classical epic poem the Aeneid

Claudius Aelianus
–
Claudius Aelianus, commonly Aelian, born at Praeneste, was a Roman author and teacher of rhetoric who flourished under Septimius Severus and probably outlived Elagabalus, who died in 222. He spoke Greek so perfectly that he was called honey-tongued, Roman-born, he preferred Greek authors and he is more attentive to marine life than might be expected, though, and this seems to reflect first-hand personal interest, he often quotes fishermen. At times he strikes the modern reader as thoroughly credulous, but at others he states that he is merely reporting what is told by others. Aelians work is one of the sources of natural history. The portions of the text that are extant are badly mangled and garbled. Conrad Gessner, the Swiss scientist and natural historian of the Renaissance, made a Latin translation of Aelians work, an English translation by A. F. Scholfield has been published in the Loeb Classical Library,3 vols. The first printing was in 1545, the standard modern text is Mervin R. Diltss, of 1974. Considerable fragments of two works, On Providence and Divine Manifestations, are preserved in the early medieval encyclopedia. Twenty letters from a farmer after the manner of Alciphron are also attributed to him, thus conclusions about actual agriculture in the Letters are as likely to evoke Latium as Attica. The fragments have been edited in 1998 by D. Domingo-Foraste, the Letters are available in the Loeb Classical Library, translated by Allen Rogers Benner and Francis H. Fobes. Historiae animalium by Gessner Aelian, On Animals, ISBN 978-0-674-99491-1, ISBN 978-0-674-99493-5, and ISBN 978-0-674-99494-2 Aelian, Historical Miscellany.

Sozopol
–
Sozopol is an ancient seaside town located 35 km south of Burgas on the southern Bulgarian Black Sea Coast. Today it is one of the seaside resorts in the country, known for the Apollonia art. Part of Burgas Province and administrative centre of the homonymous Sozopol Municipality, as of December 2009, the original name of the city is attested as Antheia but was soon renamed to Apollonia. At various times, Apollonia was known as Apollonia Pontica and Apollonia Magna, by the first century AD, the name Sozopolis began to appear in written records. During the Ottoman rule the town was known as Sizebolu, Sizeboli or Sizebolou, Sozopol is one of the oldest towns on Bulgarian Thraces Black Sea coast. The first settlement on the dates back to the Bronze Age. Undersea explorations in the region of the port reveal relics of dwellings, ceramic pottery, many anchors from the second and first millennium BC have been discovered in the towns bay, a proof of active shipping since ancient times. The current town was founded in the 7th century BC by Greek colonists from Miletus as Antheia, in 1328 Cantacuzene speaks of it as a large and populous town. The islet on which it stood is now connected with the mainland by a tongue of land. Its inhabitants, in the past mostly Greeks, lived by fishing, the town established itself as a trade and naval centre in the following centuries. It kept strong political and trade relations with the cities of Ancient Greece – Miletus, Athens, Corinth, Heraclea Pontica and its trade influence in the Thracian territories was based on a treaty with the rulers of the Odrysian kingdom dating from the fifth century BC. The symbol of the town – the anchor, present on all coins minted by Apollonia since the sixth century BC, is proof of the importance of its maritime trade, the rich town soon became an important cultural centre. At these times it was called Apollonia Magna, ruled in turn by the Byzantine, Bulgarian and Ottoman Empires, Sozopol was assigned to the newly independent Bulgaria in the 19th century. At the outbreak of the Greek War of Independence prominent local personalities were arrested and executed by the Ottoman authorities due to participation in the preparations of the struggle, almost all of its Greek population was exchanged with Bulgarians from Eastern Thrace in the aftermath of the Balkan Wars. In 2011 the remainings of an ancient Greek settlement, part of Apollonia, were excavated in the island of St. Kirik off Sozopolis. Since 1984 Sozopol hosts the Apollonia art festivities every September, which include theatre shows, exhibitions, movies, musical and dance performances, book presentations, bishops are recorded as resident there from at least 431. At least eight bishops are known, Athanasius, Peter, Euthymius and Ignatius, Theodosius, Joannicius, the titular resided at Agathopolis, in Ottoman days called Akhtébolou. Eubel mentions four Latin bishops of the 14th century, the bishopric is included in the Catholic Churchs list of titular sees as Sozopolis in Haemimonto and as a suffragan of Hadrianopolis in Haemimonto

Black Sea
–
The Black Sea is a body of water between Eastern Europe and Western Asia, bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. It is supplied by a number of rivers, such as the Danube, Dnieper, Rioni, Southern Bug. The Black Sea has an area of 436,400 km2, a depth of 2,212 m. It is constrained by the Pontic Mountains to the south and by the Caucasus Mountains to the east, the longest east-west extent is about 1,175 km. The Black Sea has a water balance, that is, a net outflow of water 300 km3 per year through the Bosphorus. Mediterranean water flows into the Black Sea as part of a two-way hydrological exchange, the Black Sea drains into the Mediterranean Sea and then the Atlantic Ocean, via the Aegean Sea and various straits. The Bosphorus Strait connects it to the Sea of Marmara, and these waters separate Eastern Europe and Western Asia. The Black Sea is also connected to the Sea of Azov by the Strait of Kerch, the water level has varied significantly. Due to these variations in the level in the basin. At certain critical water levels it is possible for connections with surrounding water bodies to become established and it is through the most active of these connective routes, the Turkish Straits, that the Black Sea joins the world ocean. When this hydrological link is not present, the Black Sea is a basin, operating independently of the global ocean system. Currently the Black Sea water level is high, thus water is being exchanged with the Mediterranean. The Turkish Straits connect the Black Sea with the Aegean Sea, and comprise the Bosphorus, the Sea of Marmara, the International Hydrographic Organization defines the limits of the Black Sea as follows, On the Southwest. The Northeastern limit of the Sea of Marmara, a line joining Cape Takil and Cape Panaghia. Strabos Geographica reports that in antiquity, the Black Sea was often just called the Sea, for the most part, Graeco-Roman tradition refers to the Black Sea as the Hospitable sea, Εὔξεινος Πόντος Eúxeinos Póntos. This is a euphemism replacing an earlier Inhospitable Sea, Πόντος Ἄξεινος Póntos Áxeinos, strabo thinks that the Black Sea was called inhospitable before Greek colonization because it was difficult to navigate, and because its shores were inhabited by savage tribes. The name was changed to hospitable after the Milesians had colonized the southern shoreline and it is also possible that the epithet Áxeinos arose by popular etymology from a Scythian word axšaina- unlit, dark, the designation Black Sea may thus date from antiquity. A map of Asia dating to 1570, entitled Asiae Nova Descriptio, from Abraham Orteliuss Theatrum Orbis Terrarum, english-language writers of the 18th century often used the name Euxine Sea to refer to the Black Sea

Achaemenid Empire
–
The Achaemenid Empire, also called the Persian Empire, was an empire based in Western Asia, founded by Cyrus the Great. The empires successes inspired similar systems in later empires and it is noted in Western history as the antagonist of the Greek city-states during the Greco-Persian Wars and for the emancipation of the Jewish exiles in Babylon. The Mausoleum at Halicarnassus, one of the Seven Wonders of the Ancient World, was built in a Hellenistic style in the empire as well. By the 7th century BC, the Persians had settled in the portion of the Iranian Plateau in the region of Persis. From this region, Cyrus the Great advanced to defeat the Medes, Lydia, Alexander, an avid admirer of Cyrus the Great, conquered the empire in its entirety by 330 BC. Upon his death, most of the former territory came under the rule of the Ptolemaic Kingdom and Seleucid Empire. The Persian population of the central plateau reclaimed power by the second century BC under the Parthian Empire, the historical mark of the Achaemenid Empire went far beyond its territorial and military influences and included cultural, social, technological and religious influences as well. Many Athenians adopted Achaemenid customs in their lives in a reciprocal cultural exchange. The impact of Cyruss edict is mentioned in Judeo-Christian texts, the empire also set the tone for the politics, heritage and history of modern Iran. Astronomical year numbering Dates are approximate, consult particular article for details Due to the duration of their reigns, Smerdis, Xerxes II. The Persian nation contains a number of tribes as listed here, the Pasargadae, Maraphii, and Maspii, upon which all the other tribes are dependent. Of these, the Pasargadae are the most distinguished, they contain the clan of the Achaemenids from which spring the Perseid kings. Other tribes are the Panthialaei, Derusiaei, Germanii, all of which are attached to the soil, the Achaemenid Empire was created by nomadic Persians. The Achaemenid Empire was not the first Iranian empire, as by 6th century BC another group of ancient Iranian peoples had established the short lived Median Empire. The Iranian peoples had arrived in the region of what is today Iran c.1000 BC and had for a number of centuries fallen under the domination of the Neo-Assyrian Empire, based in northern Mesopotamia. However, the Medes and Persians, Cimmerians, Persians and Chaldeans played a role in the overthrow of the Assyrian empire. The term Achaemenid means of the family of the Achaemenis/Achaemenes, despite the derivation of the name, Achaemenes was himself a minor seventh-century ruler of the Anshan in southwestern Iran, and a vassal of Assyria. At some point in 550 BC, Cyrus rose in rebellion against the Medes, eventually conquering the Medes and creating the first Persian empire

Greek mythology
–
It was a part of the religion in ancient Greece. Greek mythology is explicitly embodied in a collection of narratives. Greek myth attempts to explain the origins of the world, and details the lives and adventures of a variety of gods, goddesses, heroes, heroines. These accounts initially were disseminated in a tradition, today the Greek myths are known primarily from ancient Greek literature. The oldest known Greek literary sources, Homers epic poems Iliad and Odyssey, focus on the Trojan War, archaeological findings provide a principal source of detail about Greek mythology, with gods and heroes featured prominently in the decoration of many artifacts. Geometric designs on pottery of the eighth century BC depict scenes from the Trojan cycle as well as the adventures of Heracles, in the succeeding Archaic, Classical, and Hellenistic periods, Homeric and various other mythological scenes appear, supplementing the existing literary evidence. Greek mythology has had an influence on the culture, arts. Poets and artists from ancient times to the present have derived inspiration from Greek mythology and have discovered contemporary significance and relevance in the themes, Greek mythology is known today primarily from Greek literature and representations on visual media dating from the Geometric period from c. Mythical narration plays an important role in every genre of Greek literature. Nevertheless, the only general mythographical handbook to survive from Greek antiquity was the Library of Pseudo-Apollodorus and this work attempts to reconcile the contradictory tales of the poets and provides a grand summary of traditional Greek mythology and heroic legends. Apollodorus of Athens lived from c, 180–125 BC and wrote on many of these topics. His writings may have formed the basis for the collection, however the Library discusses events that occurred long after his death, among the earliest literary sources are Homers two epic poems, the Iliad and the Odyssey. Other poets completed the cycle, but these later and lesser poems now are lost almost entirely. Despite their traditional name, the Homeric Hymns have no connection with Homer. They are choral hymns from the part of the so-called Lyric age. Hesiods Works and Days, a poem about farming life, also includes the myths of Prometheus, Pandora. The poet gives advice on the best way to succeed in a dangerous world, lyrical poets often took their subjects from myth, but their treatment became gradually less narrative and more allusive. Greek lyric poets, including Pindar, Bacchylides and Simonides, and bucolic poets such as Theocritus and Bion, additionally, myth was central to classical Athenian drama

Archaic Greece
–
According to Anthony Snodgrass, the Archaic period in ancient Greece was bounded by two revolutions in the Greek world. The Archaic period saw developments in Greek politics, economics, international relations, warfare and it laid the groundwork for the Classical period, both politically and culturally. The word archaic derives from the Greek word archaios, which means old and it refers to the period in ancient Greek history before the classical. The Archaic period was considered to have been less important and historically interesting than the classical period. More recently, however, Archaic Greece has come to be studied for its own achievements, with this reassessment of the significance of the Archaic period, some scholars have objected to the term archaic, due to its connotations in English of being primitive and outdated. No term which has suggested to replace it has gained widespread currency, however. Much of our evidence about the period of ancient Greece comes from written histories. By contrast, we have no evidence from the Archaic period. We have written accounts of life in the period in the form of poetry, and epigraphical evidence, including parts of law codes, inscriptions on votive offerings, however, none of this evidence is in the quantity for which we have it in the classical period. What is lacking in evidence, however, is made up for in the rich archaeological evidence from the Archaic Greek world. Indeed, where much of our knowledge of classical Greek art comes from later Roman copies, other sources for the period are the traditions recorded by later Greek writers such as Herodotus. However, these traditions are not part of any form of history as we would recognise it today, indeed, Herodotus does not even record any dates before 480 BC. Politically, the Archaic period saw the development of the polis as the predominant unit of political organisation, many cities throughout Greece came under the rule of autocratic leaders, called tyrants. The period also saw the development of law and systems of communal decision-making, with the earliest evidence for law codes, by the end of the Archaic period, both the Athenian and Spartan constitutions seem to have developed into their classical forms. The Archaic period saw significant urbanisation, and the development of the concept of the polis as it was used in classical Greece. The urbanisation process in Archaic Greece known as synoecism – the amalgamation of small settlements into a single urban centre – took place in much of Greece in the eighth century BC. Both Athens and Argos, for instance, began to coalesce into single settlements around the end of that century and these two factors created a need for a new form of political organisation, as the political systems in place at the beginning of the Archaic period quickly became unworkable. Though in the part of the classical period the city of Athens was both culturally and politically dominant, it was not until the late sixth century that it became a leading power in Greece

City-state
–
A city-state is a sovereign state that consists of a city and its dependent territories. A great deal of consensus exists that the term applies to Singapore, Monaco. A number of small states share similar characteristics, and therefore are sometimes also cited as modern city-states. Occasionally, other states with high population densities, such as San Marino, are also cited. Several non-sovereign cities enjoy a degree of autonomy, and are sometimes considered city-states. Hong Kong and Macau, along with independent members of the United Arab Emirates, most notably Dubai, scholars have classed the Viking colonial cities in medieval Ireland, most importantly Dublin, as city-states. In Cyprus, the Phoenician settlement of Kition was a city-state that existed from around 800 BC until the end of the 4th century BC. The success of regional units coexisting as autonomous actors in loose geographical and cultural unity, as in Italy and Greece. However, such small political entities often survived only for short periods because they lacked the resources to defend themselves against incursions by larger states, thus they inevitably gave way to larger organisations of society, including the empire and the nation-state. In the history of Mainland Southeast Asia, aristocratic groups, Buddhist leaders, the system existed until the 19th century when colonization by European powers, and Thailands resulted in the adoption of the modern concept of statehood. In the Holy Roman Empire the Free Imperial Cities enjoyed a considerable autonomy, some, like the three Hanseatic cities of Bremen, Hamburg and Lübeck, pooled their economic relations with foreign powers and were able to wield considerable diplomatic clout. Under Habsburg rule the city of Fiume had the status of a Corpus separatum, a later city-state, though lacking sovereignty, was West Berlin, being a state legally not belonging to any other state, but ruled by the Western Allies. They allowed – notwithstanding their overlordship as occupant powers – its internal organisation as one state simultaneously being a city, though West Berlin maintained close ties to the West German Federal Republic of Germany, it was legally never part of it. But the idea of leaving the United States proved too radical even in the turmoil of 1861 and was poorly received, the war, and especially conscription, was nevertheless often unpopular in the city, sparking the deadly New York Draft Riots. The neighboring City of Brooklyn, in contrast, was staunchly Unionist, the Free City of Danzig was a semi-autonomous city-state that existed between 1920 and 1939, consisting of the Baltic Sea port of Danzig and nearly 200 towns in the surrounding areas. It was created on 15 November 1920 under the terms of Article 100 of the 1919 Treaty of Versailles after the end of World War I. Its territory of 28 km2 comprised the city of Fiume and rural areas to its north, with a corridor to its west connecting it to Italy, the Shanghai International Settlement was an international zone with its own legal system, postal service, and currency. The Klaipėda Region or Memel Territory was defined by the Treaty of Versailles in 1920 when it was put under the administration of the Council of Ambassadors
