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

Roman Empire
–
Civil wars and executions continued, culminating in the victory of Octavian, Caesars adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavians power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power, the imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. The first two centuries of the empires existence were a period of unprecedented political stability and prosperity known as the Pax Romana, following Octavians victory, the size of the empire was dramatically increased. After the assassination of Caligula in 41, the senate briefly considered restoring the republic, under Claudius, the empire invaded Britannia, its first major expansion since Augustus. Vespasian emerged triumphant in 69, establishing the Flavian dynasty, before being succeeded by his son Titus and his short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. The senate then appointed the first of the Five Good Emperors, the empire reached its greatest extent under Trajan, the second in this line. A period of increasing trouble and decline began with the reign of Commodus, Commodus assassination in 192 triggered the Year of the Five Emperors, of which Septimius Severus emerged victorious. The assassination of Alexander Severus in 235 led to the Crisis of the Third Century in which 26 men were declared emperor by the Roman Senate over a time span. It was not until the reign of Diocletian that the empire was fully stabilized with the introduction of the Tetrarchy, which saw four emperors rule the empire at once. This arrangement was unsuccessful, leading to a civil war that was finally ended by Constantine I. Constantine subsequently shifted the capital to Byzantium, which was renamed Constantinople in his honour and it remained the capital of the east until its demise. Constantine also adopted Christianity which later became the state religion of the empire. However, Augustulus was never recognized by his Eastern colleague, and separate rule in the Western part of the empire ceased to exist upon the death of Julius Nepos. The Eastern Roman Empire endured for another millennium, eventually falling to the Ottoman Turks in 1453, the Roman Empire was among the most powerful economic, cultural, political and military forces in the world of its time. It was one of the largest empires in world history, at its height under Trajan, it covered 5 million square kilometres. It held sway over an estimated 70 million people, at that time 21% of the entire population. Throughout the European medieval period, attempts were made to establish successors to the Roman Empire, including the Empire of Romania, a Crusader state. Rome had begun expanding shortly after the founding of the republic in the 6th century BC, then, it was an empire long before it had an emperor

Civilization
–
Historically, a civilization was a so-called advanced culture in contrast to more supposedly primitive cultures. As an uncountable noun, civilization also refers to the process of a society developing into a centralized, urbanized, stratified structure, Civilization concentrates power, extending human control over the rest of nature, including over other human beings. The earlier neolithic technology and lifestyle was established first in the Middle East, and later in the Yangtze and Yellow River basins in China, similar pre-civilized neolithic revolutions also began independently from 7,000 BCE in such places as northwestern South America and Mesoamerica. These were among the six civilizations worldwide that arose independently, Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BCE, with civilizations developing from 6,500 years ago. Towards the end of the Neolithic period, various elitist Chalcolithic civilizations began to rise in various cradles from around 3300 BCE. Chalcolithic civilizations, as defined above, also developed in Pre-Columbian Americas and, despite an early start in Egypt, Axum and Kush, the English word civilization comes from the 16th-century French civilisé, from Latin civilis, related to civis and civitas. The fundamental treatise is Norbert Eliass The Civilizing Process, which traces social mores from medieval courtly society to the Early Modern period, in The Philosophy of Civilization, Albert Schweitzer outlines two opinions, one purely material and the other material and ethical. Adjectives like civility developed in the mid-16th century, the abstract noun civilization, meaning civilized condition, came in the 1760s, again from French. The word was therefore opposed to barbarism or rudeness, in the pursuit of progress characteristic of the Age of Enlightenment. In the late 1700s and early 1800s, during the French revolution, civilization was used in the singular, never in the plural and this is still the case in French. The use of civilizations as a noun was in occasional use in the 19th century. Only in this sense does it become possible to speak of a medieval civilization. Already in the 18th century, civilization was not always seen as an improvement, one historically important distinction between culture and civilization is from the writings of Rousseau, particularly his work about education, Emile. From this, a new approach was developed, especially in Germany, first by Johann Gottfried Herder and this sees cultures as natural organisms, not defined by conscious, rational, deliberative acts, but a kind of pre-rational folk spirit. Civilization, in contrast, though more rational and more successful in material progress, is unnatural and leads to vices of social life such as guile, hypocrisy, envy and avarice. In World War II, Leo Strauss, having fled Germany, argued in New York that this opinion of civilization was behind Nazism, Social scientists such as V. Gordon Childe have named a number of traits that distinguish a civilization from other kinds of society. Andrew Nikiforuk argues that civilizations relied on shackled human muscle and it took the energy of slaves to plant crops, clothe emperors, and build cities and considers slavery to be a common feature of pre-modern civilizations. All civilizations have depended on agriculture for subsistence, grain farms can result in accumulated storage and a surplus of food, particularly when people use intensive agricultural techniques such as artificial fertilization, irrigation and crop rotation

Ecumenism
–
Ecumenism refers to efforts by Christians of different church traditions to develop closer relationships and better understandings. The term is often used to refer to efforts towards the visible. The terms ecumenism and ecumenical come from the Greek οἰκουμένη, which means the inhabited world. The ecumenical vision comprises both the search for the unity of the Church and the whole inhabited earth as the concern of all Christians. Used in this sense, the term carries no connotation of re-uniting the historically separated Christian denominations. Historically, the word was used in the context of large ecumenical councils that were organized under the auspices of Roman Emperors to clarify matters of Christian theology. These Ecumenical Councils brought together bishops from around the world as they knew it at the time. There were a total of seven ecumenical councils accepted by both Eastern Orthodoxy and Roman Catholicism held before the Great Schism, thus, the modern meaning of the world ecumenical and ecumenism derives from this pre-modern sense of Christian unity, and the impulse to recreate this unity again. Ecumenism and nondenominational or postdenominational movements are not necessarily the same thing, while some of these can be ecumenical in intent, normally nondenominationalism seeks no common organizing principle nor works toward the unity of Christians. If ecumenism is the quest for Christian unity, it must be understood what the divisions are which must be overcome, Christianity is the largest religion in the world and the various divisions have commonalities and differences in tradition, theology, church government, doctrine, and language. The exact number of denominations is disputed, based on differing definitions used. The largest number often quoted is approximately 45,000 from the Center for the Study of Global Christianity at Gordon-Conwell Theological Seminary, the World Christian Encyclopedia lists approximately 33,000 in 2001. Yet, at the time, the World Council of Churches counts only 348 member churches. This, with the Catholic Churchs 1.25 billion Christians indicates that 349 churches/denominations already account for nearly 80% of the worlds Christian population, One problem with the larger numbers is that single denominations can be counted multiple times. For example, the Catholic Church is a church, or communion. Further, the Catholic Church presence in each country is counted as a different denomination - though this is in no way an ecclesiologically accurate definition and this can result in the one Catholic Church being counted as 242 distinct denominations, as in the World Christian Encyclopedia. Other denominations may be very small remnants of once larger churches, the United Society of Believers in Christs Second Appearing have only three full members, for example, yet are a distinct denomination. Most current divisions are the result of historical schisms - a break in the communion between previously united Churches, bishops, or communities

Cartography
–
Cartography is the study and practice of making maps. Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively, the fundamental problems of traditional cartography are to, Set the maps agenda and select traits of the object to be mapped. This is the concern of map editing, traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. Represent the terrain of the object on flat media. This is the concern of map projections, eliminate characteristics of the mapped object that are not relevant to the maps purpose. This is the concern of generalization, reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization, orchestrate the elements of the map to best convey its message to its audience. This is the concern of map design, modern cartography constitutes many theoretical and practical foundations of geographic information systems. The earliest known map is a matter of debate, both because the term map isnt well-defined and because some artifacts that might be maps might actually be something else. A wall painting that might depict the ancient Anatolian city of Çatalhöyük has been dated to the late 7th millennium BCE, the oldest surviving world maps are from 9th century BCE Babylonia. One shows Babylon on the Euphrates, surrounded by Assyria, Urartu and several cities, all, in turn, another depicts Babylon as being north of the world center. The ancient Greeks and Romans created maps since Anaximander in the 6th century BCE, in the 2nd century AD, Ptolemy wrote his treatise on cartography, Geographia. This contained Ptolemys world map – the world known to Western society. As early as the 8th century, Arab scholars were translating the works of the Greek geographers into Arabic, in ancient China, geographical literature dates to the 5th century BCE. The oldest extant Chinese maps come from the State of Qin, dated back to the 4th century BCE, in the book of the Xin Yi Xiang Fa Yao, published in 1092 by the Chinese scientist Su Song, a star map on the equidistant cylindrical projection. Early forms of cartography of India included depictions of the pole star and these charts may have been used for navigation. Mappa mundi are the Medieval European maps of the world, approximately 1,100 mappae mundi are known to have survived from the Middle Ages. Of these, some 900 are found illustrating manuscripts and the remainder exist as stand-alone documents, the Arab geographer Muhammad al-Idrisi produced his medieval atlas Tabula Rogeriana in 1154

World map
–
A world map is a map of most or all of the surface of the Earth. World maps form a category of maps due to the problem of projection. Maps by necessity distort the presentation of the earths surface and these distortions reach extremes in a world map. The many ways of projecting the earth reflect diverse technical and aesthetic goals for world maps, World maps are also distinct for the global knowledge required to construct them. A meaningful map of the world could not be constructed before the European Renaissance because less than half of the earths coastlines, new knowledge of the earths surface has been accumulating ever since and continues to this day. Maps of the world generally focus either on political features or on physical features, political maps emphasize territorial boundaries and human settlement. Physical maps show geographic features such as mountains, soil type or land use, geological maps show not only the surface, but characteristics of the underlying rock, fault lines, and subsurface structures. Choropleth maps use color hue and intensity to contrast differences between regions, such as demographic or economic statistics, a map is made using a map projection, which is any method of representing a globe on a plane. All projections distort distances and directions, and each projection distributes those distortions differently, perhaps the most well known projection is the Mercator Projection, originally designed as a nautical chart. A thematic map shows geographic information about one or a few focused subjects and these maps can portray physical, social, political, cultural, economic, sociological, agricultural, or any other aspects of a city, state, region, nation, or continent. Early world maps cover depictions of the world from the Iron Age to the Age of Discovery, old maps provide much information about what was known in times past, as well as the philosophy and cultural basis of the map, which were often much different from modern cartography. Maps are one means by which scientists distribute their ideas and pass them on to future generations, the World Map, 1300–1492, The Persistence of Tradition and Transformation.

Mappa mundi
–
A mappa mundi is any medieval European map of the world. Such maps range in size and complexity from simple schematic maps 25 millimetres or less across to elaborate wall maps, the term derives from the Medieval Latin words mappa and mundi. Approximately 1,100 mappae mundi are known to have survived from the Middle Ages, of these some 900 are found illustrating manuscripts and the remainder exist as stand-alone documents. Zonal maps are pictures of the East Hemisphere, because most surviving Zonal maps are found illustrating Macrobius Commentary on Ciceros Dream of Scipio, this type of map is sometimes called Macrobian. In their simplest and most common form, Zonal mappae mundi are merely circles divided into five parallel zones, T-O maps, unlike zonal maps, illustrate only the habitable portion of the world known in Roman and medieval times. The landmass was illustrated as a divided into three portions by a T. These three divisions were the continents of Asia, Africa and Europe, the vast majority of T-O maps place east at the top, hence the term orienting a map from the Latin word oriens for east. The assertion that T-O maps depict a flat earth, while common, is unwarranted, the circle of the lands in a T-O can just as easily be fit onto the sphere of the Earth as onto a flat, disk-shaped Earth. Fourteen large quadripartite maps are found illustrating different manuscripts of Beatus of Liébanas popular Commentary on the Apocalypse of St John and these Beatus maps are believed to derive from a single original which was used to illustrate the missions of the twelve apostles of Jesus Christ. The complex or great world maps are the most famous mappae mundi, although most employ a modified T-O scheme, they are considerably more detailed than their smaller T-O cousins. These maps show coastal details, mountains, rivers, cities, towns, some include figures and stories from history, the Bible and classical mythology. Also shown on maps are exotic plants, beasts and races known to Medieval scholars only through Roman. Prior to its destruction in World War II, the Ebstorf map at 3.5 m across was the largest surviving mappa mundi, today that honor is held by the surviving center portion of the Hereford map which is 147 cm across and 175 cm top to bottom. Other important maps in this group are the Cotton or Anglo-Saxon map, the Psalter map, the somewhat later mappae mundi that accompany the popular Polychronicon of Ranulf Higden should probably be viewed as degenerate form of the earlier complex maps. Complex mappae mundi include, To modern eyes, mappae mundi can look superficially primitive, however, mappae mundi were never meant to be used as navigational charts and they make no pretence of showing the relative areas of land and water. Rather, mappae mundi were schematic and were meant to different principles. The simplest mappae mundi were diagrams meant to preserve and illustrate classical learning easily, the zonal maps should be viewed as a kind of teaching aid—easily reproduced and designed to reinforce the idea of the Earths sphericity and climate zones. T-O maps were designed to illustrate the three land masses of the world as it was known to the Romans and their medieval European heirs

Late Antiquity
–
Late antiquity is a periodization used by historians to describe the time of transition from classical antiquity to the Middle Ages in mainland Europe, the Mediterranean world, and the Near East. The development of the periodization has generally been accredited to historian Peter Brown, precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD. Generally, it can be thought of as from the end of the Roman Empires Crisis of the Third Century to, in the East, the early Islamic period, following the Muslim conquests in the mid–7th century. In the West the end was earlier, with the start of the Early Medieval period typically placed in the 6th century, beginning with Constantine the Great, Christianity was made legal in the Empire, and a new capital was founded at Constantinople. The resultant cultural fusion of Greco-Roman, Germanic and Christian traditions formed the foundations of the subsequent culture of Europe, the term Spätantike, literally late antiquity, has been used by German-speaking historians since its popularization by Alois Riegl in the early 20th century. Concurrently, some migrating Germanic tribes such as the Ostrogoths and Visigoths saw themselves as perpetuating the Roman tradition, Constantine confirmed the legalization of the religion through the so-called Edict of Milan in 313, jointly issued with his rival in the East, Licinius. Monasticism was not the only new Christian movement to appear in Late Antiquity, notable in this regard is the topic of the Fifty Bibles of Constantine. Within the recently legitimized Christian community of the 4th century, a division could be distinctly seen between the laity and an increasingly celibate male leadership. Celibate and detached, the clergy became an elite equal in prestige to urban notables. The Late Antique period also saw a transformation of the political and social basis of life in. The later Roman Empire was in a sense a network of cities, archaeology now supplements literary sources to document the transformation followed by collapse of cities in the Mediterranean basin. Burials within the urban precincts mark another stage in dissolution of traditional urbanistic discipline, overpowered by the attraction of saintly shrines, in Roman Britain, the typical 4th- and 5th-century layer of black earth within cities seems to be a result of increased gardening in formerly urban spaces. A similar though less marked decline in population occurred later in Constantinople. In Europe there was also a decline in urban populations. As a whole, the period of antiquity was accompanied by an overall population decline in almost all Europe. Long-distance markets disappeared, and there was a reversion to a degree of local production and consumption, rather than webs of commerce. The degree and extent of discontinuity in the cities of the Greek East is a moot subject among historians. In the western Mediterranean, the new cities known to be founded in Europe between the 5th and 8th centuries were the four or five Visigothic victory cities

Middle Ages
–
In the history of Europe, the Middle Ages or Medieval Period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance, the Middle Ages is the middle period of the three traditional divisions of Western history, classical antiquity, the medieval period, and the modern period. The medieval period is subdivided into the Early, High. Population decline, counterurbanisation, invasion, and movement of peoples, the large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the seventh century, North Africa and the Middle East—once part of the Byzantine Empire—came under the rule of the Umayyad Caliphate, although there were substantial changes in society and political structures, the break with classical antiquity was not complete. The still-sizeable Byzantine Empire survived in the east and remained a major power, the empires law code, the Corpus Juris Civilis or Code of Justinian, was rediscovered in Northern Italy in 1070 and became widely admired later in the Middle Ages. In the West, most kingdoms incorporated the few extant Roman institutions, monasteries were founded as campaigns to Christianise pagan Europe continued. The Franks, under the Carolingian dynasty, briefly established the Carolingian Empire during the later 8th, the Crusades, first preached in 1095, were military attempts by Western European Christians to regain control of the Holy Land from Muslims. Kings became the heads of centralised nation states, reducing crime and violence, intellectual life was marked by scholasticism, a philosophy that emphasised joining faith to reason, and by the founding of universities. Controversy, heresy, and the Western Schism within the Catholic Church paralleled the conflict, civil strife. Cultural and technological developments transformed European society, concluding the Late Middle Ages, the Middle Ages is one of the three major periods in the most enduring scheme for analysing European history, classical civilisation, or Antiquity, the Middle Ages, and the Modern Period. Medieval writers divided history into periods such as the Six Ages or the Four Empires, when referring to their own times, they spoke of them as being modern. In the 1330s, the humanist and poet Petrarch referred to pre-Christian times as antiqua, leonardo Bruni was the first historian to use tripartite periodisation in his History of the Florentine People. Bruni and later argued that Italy had recovered since Petrarchs time. The Middle Ages first appears in Latin in 1469 as media tempestas or middle season, in early usage, there were many variants, including medium aevum, or middle age, first recorded in 1604, and media saecula, or middle ages, first recorded in 1625. The alternative term medieval derives from medium aevum, tripartite periodisation became standard after the German 17th-century historian Christoph Cellarius divided history into three periods, Ancient, Medieval, and Modern. The most commonly given starting point for the Middle Ages is 476, for Europe as a whole,1500 is often considered to be the end of the Middle Ages, but there is no universally agreed upon end date. English historians often use the Battle of Bosworth Field in 1485 to mark the end of the period

Herodotus
–
Herodotus was a Greek historian who was born in Halicarnassus in the Persian Empire and lived in the fifth century BC, a contemporary of Socrates. The Histories is the work which he is known to have produced. Despite Herodotus historical significance, little is known of his personal life and his place in history and his significance may be understood according to the traditions within which he worked. His work is the earliest Greek prose to have survived intact, of these only fragments of Hecataeuss work survive yet they allow us glimpses into the kind of tradition within which Herodotus wrote his own Histories. In his introduction to Hecataeus’s work, Genealogies, This points forward to the ‘folksy’ yet ‘international’ outlook typical of Herodotus. Yet, one scholar has described the work of Hecataeus as “a curious false start to history” since despite his critical spirit. It is possible that Herodotus borrowed much material from Hecataeus, as stated by Porphyry in a recorded by Eusebius. But Hecataeus did not record events that had occurred in living memory, unlike Herodotus, Herodotus claims to be better informed than his predecessors by relying on empirical observation to correct their excessive schematism. For example, He argues for continental asymmetry as opposed to the theory of a perfectly circular earth with Europe. Yet, he retains idealizing tendencies, as in his notions of the Danube. His debt to previous authors of prose ‘histories’ might be questionable, however, this point is one of the most contentious issues in modern scholarship. It is on account of the strange stories and the folk-tales he reported that his critics in early modern times branded him “The Father of Lies”. Even his own contemporaries found reason to scoff at his achievement, similarly, the Athenian historian Thucydides dismissed Herodotus as a “logos-writer”. Moreover, Thucydides developed a historical topic more in keeping with the Greek world-view, the interplay of civilizations was more relevant to Greeks living in Anatolia, such as Herodotus himself, for whom life within a foreign civilization was a recent memory. Modern scholars generally turn to Herodotus’s own writing for reliable information about his life, supplemented with ancient yet much later sources, modern accounts of his life typically go something like this, Herodotus was born at Halicarnassus around 484 BC. His name is not mentioned later in the tribute list of the Athenian Delian League, the epic poet Panyassis – a relative of Herodotus – is reported to have taken part in a failed uprising. Herodotus expresses affection for the island of Samos, and this is an indication that he might have lived there in his youth. So it is possible that his family was involved in an uprising against Lygdamis, leading to a period of exile on Samos, Herodotus wrote his Histories in the Ionian dialect, yet he was born in Halicarnassus, which was a Dorian settlement

Ancient Greek
–
Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often divided into the Archaic period, Classical period. It is antedated in the second millennium BC by Mycenaean Greek, the language of the Hellenistic phase is known as Koine. Koine is regarded as a historical stage of its own, although in its earliest form it closely resembled Attic Greek. Prior to the Koine period, Greek of the classic and earlier periods included several regional dialects, Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical phases of the language, Ancient Greek was a pluricentric language, divided into many dialects. The main dialect groups are Attic and Ionic, Aeolic, Arcadocypriot, some dialects are found in standardized literary forms used in literature, while others are attested only in inscriptions. There are also several historical forms, homeric Greek is a literary form of Archaic Greek used in the epic poems, the Iliad and Odyssey, and in later poems by other authors. Homeric Greek had significant differences in grammar and pronunciation from Classical Attic, the origins, early form and development of the Hellenic language family are not well understood because of a lack of contemporaneous evidence. Several theories exist about what Hellenic dialect groups may have existed between the divergence of early Greek-like speech from the common Proto-Indo-European language and the Classical period and they have the same general outline, but differ in some of the detail. The invasion would not be Dorian unless the invaders had some relationship to the historical Dorians. The invasion is known to have displaced population to the later Attic-Ionic regions, the Greeks of this period believed there were three major divisions of all Greek people—Dorians, Aeolians, and Ionians, each with their own defining and distinctive dialects. Often non-west is called East Greek, Arcadocypriot apparently descended more closely from the Mycenaean Greek of the Bronze Age. Boeotian had come under a strong Northwest Greek influence, and can in some respects be considered a transitional dialect, thessalian likewise had come under Northwest Greek influence, though to a lesser degree. Most of the dialect sub-groups listed above had further subdivisions, generally equivalent to a city-state and its surrounding territory, Doric notably had several intermediate divisions as well, into Island Doric, Southern Peloponnesus Doric, and Northern Peloponnesus Doric. The Lesbian dialect was Aeolic Greek and this dialect slowly replaced most of the older dialects, although Doric dialect has survived in the Tsakonian language, which is spoken in the region of modern Sparta. Doric has also passed down its aorist terminations into most verbs of Demotic Greek, by about the 6th century AD, the Koine had slowly metamorphosized into Medieval Greek

Ptolemy
–
Claudius Ptolemy was a Greek writer, known as a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, beyond that, few reliable details of his life are known. His birthplace has been given as Ptolemais Hermiou in the Thebaid in a statement by the 14th-century astronomer Theodore Meliteniotes. This is a very late attestation, however, and there is no reason to suppose that he ever lived elsewhere than Alexandria. Ptolemy wrote several treatises, three of which were of importance to later Byzantine, Islamic and European science. The first is the astronomical treatise now known as the Almagest, although it was entitled the Mathematical Treatise. The second is the Geography, which is a discussion of the geographic knowledge of the Greco-Roman world. The third is the treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika but more known as the Tetrabiblos from the Greek meaning Four Books or by the Latin Quadripartitum. The name Claudius is a Roman nomen, the fact that Ptolemy bore it indicates he lived under the Roman rule of Egypt with the privileges and political rights of Roman citizenship. It would have suited custom if the first of Ptolemys family to become a citizen took the nomen from a Roman called Claudius who was responsible for granting citizenship, if, as was common, this was the emperor, citizenship would have been granted between AD41 and 68. The astronomer would also have had a praenomen, which remains unknown and it occurs once in Greek mythology, and is of Homeric form. All the kings after him, until Egypt became a Roman province in 30 BC, were also Ptolemies, abu Mashar recorded a belief that a different member of this royal line composed the book on astrology and attributed it to Ptolemy. The correct answer is not known”, Ptolemy wrote in Greek and can be shown to have utilized Babylonian astronomical data. He was a Roman citizen, but most scholars conclude that Ptolemy was ethnically Greek and he was often known in later Arabic sources as the Upper Egyptian, suggesting he may have had origins in southern Egypt. Later Arabic astronomers, geographers and physicists referred to him by his name in Arabic, Ptolemys Almagest is the only surviving comprehensive ancient treatise on astronomy. Ptolemy presented his models in convenient tables, which could be used to compute the future or past position of the planets. The Almagest also contains a catalogue, which is a version of a catalogue created by Hipparchus

Geography (Ptolemy)
–
Its translation into Arabic in the 9th century and Latin in 1406 was highly influential on the geographical knowledge and cartographic traditions of the medieval Caliphate and Renaissance Europe. Versions of Ptolemys work in antiquity were probably proper atlases with attached maps, no Greek manuscript of the Geography survives from earlier than the 13th century. In Europe, maps were sometimes made using the coordinates provided by the text. Later scribes and publishers could then copy these new maps, as Athanasius did for the emperor Andronicus II Palaeologus, the three earliest surviving texts with maps are those from Constantinople based on Planudess work. The first Latin translation of texts was made in 1406 or 1407 by Jacobus Angelus in Florence, Italy. It is not thought that his edition had maps, although Manuel Chrysoloras had given Palla Strozzi a Greek copy of Planudess maps in Florence in 1397, the Geography consists of three sections, divided among 8 books. Book I is a treatise on cartography, describing the methods used to assemble, from Book II through the beginning of Book VII, a gazetteer provides longitude and latitude values for the world known to the ancient Romans. The rest of Book VII provides details on three projections to be used for the construction of a map of the world, varying in complexity and fidelity, Book VIII constitutes an atlas of regional maps. The maps include a recapitulation of some of the values given earlier in the work, Maps based on scientific principles had been made in Europe since the time of Eratosthenes in the 3rd century BC. Ptolemy improved the treatment of map projections and he provided instructions on how to create his maps in the first section of the work. The gazetteer section of Ptolemys work provided latitude and longitude coördinates for all the places and his Prime Meridian ran through the Fortunate Isles, the westernmost land recorded, at around the position of El Hierro in the Canary Islands. The maps spanned 180 degrees of longitude from the Fortunate Isles in the Atlantic to China, Ptolemy was aware that Europe knew only about a quarter of the globe. Ptolemys work included a large and less detailed world map and then separate. As early as the 1420s, these maps were complemented by extra-Ptolemaic regional maps depicting. The original treatise by Marinus of Tyre that formed the basis of Ptolemys Geography has been completely lost, a world map based on Ptolemy was displayed in Augustodunum in late Roman times. Pappus, writing at Alexandria in the 4th century, produced a commentary on Ptolemys Geography, for instance, Grant Parker argues that it would be highly implausible for them to have constructed the Bay of Bengal as precisely as they did without the accounts of sailors. Muslim cartographers were using copies of Ptolemys Almagest and Geography by the 9th century, a 1037 copy of these are the earliest extant maps from Islamic lands. Nallino suggests that the work was not based on Ptolemy but on a world map

Eratosthenes
–
Eratosthenes of Cyrene was a Greek mathematician, geographer, poet, astronomer, and music theorist. He was a man of learning, becoming the librarian at the Library of Alexandria. He invented the discipline of geography, including the terminology used today and he is best known for being the first person to calculate the circumference of the Earth, which he did by applying a measuring system using stadia, a standard unit of measure during that time period. He was also the first to calculate the tilt of the Earths axis, additionally, he may have accurately calculated the distance from the Earth to the Sun and invented the leap day. He created the first map of the world, incorporating parallels, Eratosthenes was the founder of scientific chronology, he endeavored to revise the dates of the chief literary and political events from the conquest of Troy. In number theory, he introduced the sieve of Eratosthenes, an efficient method of identifying prime numbers and he was a figure of influence in many fields. According to an entry in the Suda, his critics scorned him, nonetheless, his devotees nicknamed him Pentathlos after the Olympians who were well rounded competitors, for he had proven himself to be knowledgeable in every area of learning. Eratosthenes yearned to understand the complexities of the entire world, the son of Aglaos, Eratosthenes was born in 276 BC in Cyrene. Alexander the Great conquered Cyrene in 332 BC, and following his death in 323 BC, its rule was given to one of his generals, Ptolemy I Soter, the founder of the Ptolemaic Kingdom. Under Ptolemaic rule the economy prospered, based largely on the export of horses and silphium, Cyrene became a place of cultivation, where knowledge blossomed. Eratosthenes went to Athens to further his studies, there he was taught Stoicism by its founder, Zeno of Citium, in philosophical lectures on living a virtuous life. He then studied under Ariston of Chios, who led a more cynical school of philosophy and he also studied under the head of the Platonic Academy, who was Arcesilaus of Pitane. His interest in Plato led him to write his very first work at a level, Platonikos. Eratosthenes was a man of many perspectives and investigated the art of poetry under Callimachus and he was a talented and imaginative poet. He wrote poems, one in hexameters called Hermes, illustrating the life history. He wrote Chronographies, a text that scientifically depicted dates of importance and this work was highly esteemed for its accuracy. George Syncellus was later able to preserve from Chronographies a list of 38 kings of the Egyptian Thebes, Eratosthenes also wrote Olympic Victors, a chronology of the winners of the Olympic Games. It is not known when he wrote his works, but they highlighted his abilities and these works and his great poetic abilities led the pharaoh Ptolemy III Euergetes to seek to place him as a librarian at the Library of Alexandria in the year 245 BC

Cyrene, Libya
–
Cyrene was an ancient Greek and Roman city near present-day Shahhat, Libya. It was the oldest and most important of the five Greek cities in the region and it gave eastern Libya the classical name Cyrenaica that it has retained to modern times. Cyrene lies in a valley in the Jebel Akhdar uplands. The city was named after a spring, Kyre, which the Greeks consecrated to Apollo and it was also the seat of the Cyrenaics, a famous school of philosophy in the 3rd century BC, founded by Aristippus, a disciple of Socrates. It was then nicknamed the Athens of Africa, Grinus, son of Aesanius a descendant of Theras, and king of the island of Thera, had visited the Oracle and offered a hecatomb to the Oracle on sundry matters. The Oracle had offered the advice to found a new city in Libya, many years had passed and the advice was not taken, and Thera had succumbed to a horrific drought and all of the crops and trees had perished. Not knowing how to get to Libya they sent a messenger to Crete to find someone to lead them on their journey and they found a dealer in purple dyes named Corobius. He had once traveled to an island across from Libya called Platea, Grinus and Corobius sailed to Platea, when they reached their destination they left Corobius with months of supplies and Grinus went back to Thera to collect men to settle the newly made colony. After two years of settling the colony they had success and went back to the Oracle to get advice. The Oracle had repeated her advice to move directly to the country of Libya instead of across from Libya, so they moved to a place called Aziris. They settled there for six years, and were successful until the Libyans visited the settlement of Aziris to convince the people to move further inland. They were swayed by the Libyans to move and settled into what is now Cyrene, traditional details concerning the founding of the city are contained in Herodotus Histories IV. Cyrene promptly became the town of ancient Libya and established commercial relations with all the Greek cities. Soon after 460 BC it became a republic, in 413 BC, during the Peloponnesian War, Cyrene supplied Spartan forces with two triremes and pilots. After the death of Alexander the Great of Macedon, the Cyrenian republic became subject to the Ptolemaic dynasty, ophelas, the general who occupied the city in Ptolemy Is name, ruled the city almost independently until his death, when Ptolemys son-in-law Magas received governorship of the territory. In 276 BC Magas crowned himself king and declared de facto independence, the invasion was unsuccessful and in 250 BC, after Magas death, the city was reabsorbed into Ptolemaic Egypt. Cyrenaica became part of the Ptolemaic empire controlled from Alexandria, in 74 BC the territory was formally transformed into a Roman province. The inhabitants of Cyrene at the time of Sulla were divided into four classes, citizens, farmers, resident aliens, the ruler of the town, Ptolemy Apion, bequeathed it to the Romans, but it kept its self-government

Circumference of the Earth
–
The Equator usually refers to an imaginary line on the Earths surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. The Equator is about 40,075 kilometres long, some 78. 7% lies across water and 21. 3% over land, other planets and astronomical bodies have equators similarly defined. Generally, an equator is the intersection of the surface of a sphere with the plane that is perpendicular to the spheres axis of rotation. The latitude of the Earths equator is by definition 0° of arc, the equator is the only line of latitude which is also a great circle — that is, one whose plane passes through the center of the globe. The plane of Earths equator when projected outwards to the celestial sphere defines the celestial equator, in the cycle of Earths seasons, the plane of the equator passes through the Sun twice per year, at the March and September equinoxes. To an observer on the Earth, the Sun appears to travel North or South over the equator at these times, light rays from the center of the Sun are perpendicular to the surface of the Earth at the point of solar noon on the Equator. Locations on the Equator experience the quickest sunrises and sunsets because the sun moves nearly perpendicular to the horizon for most of the year. The Earth bulges slightly at the Equator, the diameter of the Earth is 12,750 kilometres. Because the Earth spins to the east, spacecraft must also launch to the east to take advantage of this Earth-boost of speed, seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earths axis relative to the plane of revolution. During the year the northern and southern hemispheres are inclined toward or away from the sun according to Earths position in its orbit, the hemisphere inclined toward the sun receives more sunlight and is in summer, while the other hemisphere receives less sun and is in winter. At the equinoxes, the Earths axis is not tilted toward the sun, instead it is perpendicular to the sun meaning that the day is about 12 hours long, as is the night, across the whole of the Earth. Near the Equator there is distinction between summer, winter, autumn, or spring. The temperatures are usually high year-round—with the exception of high mountains in South America, the temperature at the Equator can plummet during rainstorms. In many tropical regions people identify two seasons, the wet season and the dry season, but many places close to the Equator are on the oceans or rainy throughout the year, the seasons can vary depending on elevation and proximity to an ocean. The Equator lies mostly on the three largest oceans, the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean. The highest point on the Equator is at the elevation of 4,690 metres, at 0°0′0″N 77°59′31″W and this is slightly above the snow line, and is the only place on the Equator where snow lies on the ground. At the Equator the snow line is around 1,000 metres lower than on Mount Everest, the Equator traverses the land of 11 countries, it also passes through two island nations, though without making a landfall in either. Starting at the Prime Meridian and heading eastwards, the Equator passes through, Despite its name, however, its island of Annobón is 155 km south of the Equator, and the rest of the country lies to the north

Crates of Mallus
–
Crates of Mallus was a Greek language grammarian and Stoic philosopher, leader of the literary school and head of the library of Pergamum. He was described as the Crates from Mallus to distinguish him from other philosophers by the same name and his chief work was a critical and exegetical commentary on Homer. He is also famous for constructing the earliest known globe of the Earth and he was born in Mallus in Cilicia, and was brought up at Tarsus, and then moved to Pergamon, and there lived under the patronage of Eumenes II, and Attalus II. He was the founder of the Pergamon school of grammar, among his followers were Hermias, Zenodotus of Mallus and Herodicus of Babylon. He visited Rome as ambassador of either Eumenes, in 168 BC, Crates made a strong distinction between criticism and grammar, the latter of which he regarded as subordinate to the former. From this part of his system, Crates derived the surname of Kritikos, like Aristarchus of Samothrace, Crates gave the greatest attention to the works of Homer, from his labours upon which he was also surnamed Homerikos. He wrote a commentary on the Iliad and Odyssey in nine books, some fragments of this commentary are preserved by the scholiasts and other ancient writers. His principles were opposed to those of Aristarchus, who was the leader of the Alexandrian school, Crates was the chief representative of the allegorical theory of exegesis, and maintained that Homer intended to express scientific or philosophical truths in the form of poetry. The classic drawing of the displays the known world, or Oecumene. And Oceanus does in fact girdle the globe, but at 60 degrees South latitude, Crates Bay in Antarctica is named after Crates of Mallus.

Serica
–
Serica was one of the easternmost countries of Asia known to the Ancient Greek and Roman geographers. A similar distinction was observed during the Middle Ages between Cathay and Mangi or China. The people of Serica were the Seres, whose name was used for their region. Access to Serica was eased following the Han conquest of the Tarim Basin, some scholars, however, contend the Seres were not the Chinese themselves but tribes speaking Indo-European languages who traded with the ancient Indians, such as the Yuezhi, Saka, and Tocharians. The Latin forms Serica and Seres derive from the Greek Sērikḗ and this seems to derive from their words for silk, which since Klaproth has often been linked to the Chinese 絲, whose Old Chinese pronunciation has been reconstructed as /*ə/. The Greeks and Romans knew of silk long before they understood its origin from silkworms, other forms of the name include Serica Regio. Some classicists have argued that it was improbable that a nation would be named after an insect. Lassen claimed to have identified references to the Seres in Hindu scripture, as the Çaka, Tukhâra, beginning in the 1st century BC with Virgil, Horace, and Strabo, Roman histories offer only vague accounts of China and the silk-producing Seres of the Far East. Florus seems to have confused the Seres with peoples of India, the historian Ammianus Marcellinus wrote that the land of the Seres was enclosed by great natural walls around a river called Bautis, possibly a description of the Yellow River. From Turkic peoples of Central Asia the later Eastern Romans derived a new name for China, Taugast, by the time of the Eastern Roman ruler Justinian I, the Byzantines purchased Chinese silk from Sogdian intermediaries. However, they also smuggled out of China with the help of Nestorian monks. The first surviving European accounts of the Seres are those in Ctesiass 5th-century BC Indica, the authenticity of the account is, however, disputed. Strabos 1st-century Geography mentions the Seres in two asides, in the first passage, he mentions that some writers claim the Seres to be longer lived than the Indians of Musicanus, whom Onesicritus claimed lived to the age of 130. In the second, a passage discussing the Greco-Bactrian Kingdom, he mentions that Apollodorus of Artemita claimed the Bactrians borders stretched even as far as the Seres, Pomponius Melas De Situ Orbis names the Seres as one of three peoples inhabiting the eastern extremity of Asia. He places the Seres between the Indians to the south and the Scythians to the north, in a later passage, he notes, From these the course makes a bend and trends to the coast line which faces the east. That part which adjoins the Scythian promontory is first all impassable from snow and these tribes are the Cannibal Scythians and the Sakas, severed from one another by a region where none can dwell because of the number of wild animals. Another vast wilderness follows, occupied also by wild beasts, reaching to a mountain called Thabis which overhangs the sea, a long way from that the ridge of Taurus rises. The Seres come between the two, a race eminent for integrity and well known for the trade which they allow to be transacted behind their backs, Pliny the Elder discussed the Seres in his Natural History, Book VI, chapter xx

China
–
China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain. For millennia, Chinas political system was based on hereditary monarchies known as dynasties, in 1912, the Republic of China replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist Peoples Liberation Army in the Chinese Civil War. The Communist Party established the Peoples Republic of China in Beijing on 1 October 1949, both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory. China had the largest economy in the world for much of the last two years, during which it has seen cycles of prosperity and decline. Since the introduction of reforms in 1978, China has become one of the worlds fastest-growing major economies. As of 2016, it is the worlds second-largest economy by nominal GDP, China is also the worlds largest exporter and second-largest importer of goods. China is a nuclear weapons state and has the worlds largest standing army. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U. N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization, the BCIM, the English name China is first attested in Richard Edens 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

Latitude
–
In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earths surface. Latitude is an angle which ranges from 0° at the Equator to 90° at the poles, lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the location of features on the surface of the Earth. Without qualification the term latitude should be taken to be the latitude as defined in the following sections. Also defined are six auxiliary latitudes which are used in special applications, there is a separate article on the History of latitude measurements. Two levels of abstraction are employed in the definition of latitude and longitude, in the first step the physical surface is modelled by the geoid, a surface which approximates the mean sea level over the oceans and its continuation under the land masses. The second step is to approximate the geoid by a mathematically simpler reference surface, the simplest choice for the reference surface is a sphere, but the geoid is more accurately modelled by an ellipsoid. The definitions of latitude and longitude on such surfaces are detailed in the following sections. Lines of constant latitude and longitude together constitute a graticule on the reference surface, latitude and longitude together with some specification of height constitute a geographic coordinate system as defined in the specification of the ISO19111 standard. This is of importance in accurate applications, such as a Global Positioning System, but in common usage, where high accuracy is not required. In English texts the latitude angle, defined below, is denoted by the Greek lower-case letter phi. It is measured in degrees, minutes and seconds or decimal degrees, the precise measurement of latitude requires an understanding of the gravitational field of the Earth, either to set up theodolites or to determine GPS satellite orbits. The study of the figure of the Earth together with its field is the science of geodesy. These topics are not discussed in this article and this article relates to coordinate systems for the Earth, it may be extended to cover the Moon, planets and other celestial objects by a simple change of nomenclature. The primary reference points are the poles where the axis of rotation of the Earth intersects the reference surface, the plane through the centre of the Earth and perpendicular to the rotation axis intersects the surface at a great circle called the Equator. Planes parallel to the plane intersect the surface in circles of constant latitude. The Equator has a latitude of 0°, the North Pole has a latitude of 90° North, the latitude of an arbitrary point is the angle between the equatorial plane and the radius to that point. The latitude, as defined in this way for the sphere, is termed the spherical latitude

Thule
–
Thule was a far-northern location in classical European literature and cartography. Though often considered to be an island in antiquity, modern interpretations of what was meant by Thule often identify it as Norway, other interpretations include Orkney, Shetland, and Scandinavia. In the Late Middle Ages and Renaissance, Thule was often identified as Iceland or Greenland, another suggested location is Saaremaa in the Baltic Sea. The term ultima Thule in medieval geographies denotes any distant place located beyond the borders of the known world, sometimes it is used as a proper noun as the Latin name for Greenland when Thule is used for Iceland. The British surveyor Charles Vallancey was one of many antiquarians who argued that Ireland was Thule, the Greek explorer Pytheas is the first to have written of Thule, doing so in his now lost work, On the Ocean, after his travels between 330-320 BC. He supposedly was sent out by the Greek city of Massalia to see where their trade-goods were coming from, descriptions of some of his discoveries have survived in the works of later, often sceptical, authors. Nearly a half later, in 77, Pliny the Elder published his Natural History in which he also cites Pytheas claim that Thule is a six-day sail north of Britain. The Roman geographer Pomponius Mela placed Thule north of Scythia, after correcting for the mistakes, the scientists mapped Ptolemys Thule to the Norwegian island of Smøla. Other late classical writers and post-classical writers such as Orosius and the Irish monk Dicuil, describe Thule as being north, Dicuil described Thule as being beyond islands that seem to be the Faroe Islands, strongly suggesting Iceland. In the writings of the historian Procopius, from the first half of the sixth century and it is believed that Procopius is really talking about a part of Scandinavia, since several tribes are easily identified, including the Geats in present-day Sweden and the Sami people. He also writes that when the Herules returned, they passed the Warini and the Danes and then crossed the sea to Thule, virgil coined the term Ultima Thule meaning furthest land as a symbolic reference to denote a far-off land or an unattainable goal. The 1st century BC Greek astronomer Geminus of Rhodes claimed that the name Thule went back to a word for the polar night phenomenon – the place where the sun goes to rest. Dionysius Periegetes in his De situ habitabilis orbis also touched upon this subject as did Martianus Capella, avienus in his Ora Maritima added that during the summer on Thule night lasted only two hours, a clear reference to the midnight sun. Cleomedes referenced Pytheas journey to Thule, but added no new information, a novel in Greek by Antonius Diogenes entitled The Wonders Beyond Thule appeared c. Gerald N. Sandy, in the introduction to his translation of Photius ninth-century summary of the work, the Latin grammarian Gaius Julius Solinus in the 3rd century AD, wrote in his Polyhistor that Thule was a 5 days sail from Orkney. Ab Orcadibus Thylen usque quinque dierum ac noctium navigatio est, sed Thyle larga et diutina Pomona copiosa est, Thyle, which was distant from Orkney by a voyage of five days and nights, was fruitful and abundant in the lasting yield of its crops. The 4th century Virgilian commentator Servius also believed that Thule sat close to Orkney, Thule, insula est Oceani inter septemtrionalem et occidentalem plagam, ultra Britanniam, iuxta Orcades et Hiberniam, in hac Thule cum sol in Cancro est, perpetui dies sine noctibus dicuntur. This implies that Thule was Scotland, but in Against Rufinias, the Second Poem, Claudian writes of Thule lying icebound beneath the pole-star

Indian Ocean
–
The Indian Ocean is the third largest of the worlds oceanic divisions, covering 70,560,000 km2. It is bounded by Asia on the north, on the west by Africa, on the east by Australia, the Indian Ocean is known as Ratnākara, the mine of gems in ancient Sanskrit literature, and as Hind Mahāsāgar, in Hindi. The northernmost extent of the Indian Ocean is approximately 30° north in the Persian Gulf, the oceans continental shelves are narrow, averaging 200 kilometres in width. An exception is found off Australias western coast, where the width exceeds 1,000 kilometres. The average depth of the ocean is 3,890 m and its deepest point is Diamantina Deep in Diamantina Trench, at 8,047 m deep, Sunda Trench has a depth of 7, 258–7,725 m. North of 50° south latitude, 86% of the basin is covered by pelagic sediments. The remaining 14% is layered with terrigenous sediments, glacial outwash dominates the extreme southern latitudes. The major choke points include Bab el Mandeb, Strait of Hormuz, the Lombok Strait, the Strait of Malacca, the Indian Ocean is artificially connected to the Mediterranean Sea through the Suez Canal, which is accessible via the Red Sea. All of the Indian Ocean is in the Eastern Hemisphere and the centre of the Eastern Hemisphere is in this ocean, marginal seas, gulfs, bays and straits of the Indian Ocean include, The climate north of the equator is affected by a monsoon climate. Strong north-east winds blow from October until April, from May until October south, in the Arabian Sea the violent Monsoon brings rain to the Indian subcontinent. In the southern hemisphere, the winds are milder. When the monsoon winds change, cyclones sometimes strike the shores of the Arabian Sea, the Indian Ocean is the warmest ocean in the world. Long-term ocean temperature records show a rapid, continuous warming in the Indian Ocean, Indian Ocean warming is the largest among the tropical oceans, and about 3 times faster than the warming observed in the Pacific. Research indicates that human induced greenhouse warming, and changes in the frequency, among the few large rivers flowing into the Indian Ocean are the Zambezi, Shatt al-Arab, Indus, Godavari, Krishna, Narmada, Ganges, Brahmaputra, Jubba and Irrawaddy River. The oceans currents are controlled by the monsoon. Two large gyres, one in the northern hemisphere flowing clockwise and one south of the equator moving anticlockwise, during the winter monsoon, however, currents in the north are reversed. Deep water circulation is controlled primarily by inflows from the Atlantic Ocean, the Red Sea, north of 20° south latitude the minimum surface temperature is 22 °C, exceeding 28 °C to the east. Southward of 40° south latitude, temperatures drop quickly, surface water salinity ranges from 32 to 37 parts per 1000, the highest occurring in the Arabian Sea and in a belt between southern Africa and south-western Australia

Terra incognita
–
Terra incognita or terra ignota is a term used in cartography for regions that have not been mapped or documented. The expression is believed to be first seen in Ptolemys Geography c, the term was reintroduced in the 15th century from the rediscovery of Ptolemy’s work during the Age of Discovery. The equivalent on French maps would be terres inconnues, and some English maps may show Parts Unknown, similarly, uncharted or unknown seas would be labeled mare incognitum, Latin for unknown sea. An urban legend claims that cartographers labelled such regions with Here be dragons, however, ancient Roman and Medieval cartographers did use the phrase HIC SVNT LEONES when denoting unknown territories on maps. Alternatively, terra incognita may also refer to the hypothesized continent Terra Australis Incognita, during the 19th century terra incognita disappeared from maps of the earth, since both the coastlines and the inner parts of the continents had been fully explored. But the bottoms of the seas remain mostly un-mapped, as do many other surfaces in the solar system. The phrase is now also used metaphorically by various researchers to describe any unexplored subject or field of research, Terra, Latin for earth or land. Related English words include terrestrial, territory and terrain, Incognita, from Latin cognoscere to know, be acquainted with, which is related to English know and Greek γνῶσις gnosis knowledge. Related English words include agnostic, cognition, gnosticism, for more history of the terms, see Terra Australis, and also Etymology at Australia

Symmetry
–
Symmetry in everyday language refers to a sense of harmonious and beautiful proportion and balance. In mathematics, symmetry has a precise definition, that an object is invariant to any of various transformations. Although these two meanings of symmetry can sometimes be told apart, they are related, so they are discussed together. The opposite of symmetry is asymmetry, a geometric shape or object is symmetric if it can be divided into two or more identical pieces that are arranged in an organized fashion. This means that an object is symmetric if there is a transformation that moves individual pieces of the object, an object has rotational symmetry if the object can be rotated about a fixed point without changing the overall shape. An object has symmetry if it can be translated without changing its overall shape. An object has symmetry if it can be simultaneously translated and rotated in three-dimensional space along a line known as a screw axis. An object has symmetry if it does not change shape when it is expanded or contracted. Fractals also exhibit a form of symmetry, where small portions of the fractal are similar in shape to large portions. Other symmetries include glide reflection symmetry and rotoreflection symmetry, a dyadic relation R is symmetric if and only if, whenever its true that Rab, its true that Rba. Thus, is the age as is symmetrical, for if Paul is the same age as Mary. Symmetric binary logical connectives are and, or, biconditional, nand, xor, the set of operations that preserve a given property of the object form a group. In general, every kind of structure in mathematics will have its own kind of symmetry, examples include even and odd functions in calculus, the symmetric group in abstract algebra, symmetric matrices in linear algebra, and the Galois group in Galois theory. In statistics, it appears as symmetric probability distributions, and as skewness, symmetry in physics has been generalized to mean invariance—that is, lack of change—under any kind of transformation, for example arbitrary coordinate transformations. This concept has one of the most powerful tools of theoretical physics. See Noethers theorem, and also, Wigners classification, which says that the symmetries of the laws of physics determine the properties of the found in nature. Important symmetries in physics include continuous symmetries and discrete symmetries of spacetime, internal symmetries of particles, in biology, the notion of symmetry is mostly used explicitly to describe body shapes. Bilateral animals, including humans, are more or less symmetric with respect to the plane which divides the body into left

Antipodes
–
In geography, the antipode of any place on Earth is the point on the Earths surface that is diametrically opposite to it. A pair of antipodes are two points that are antipodal /ænˈtɪpədəl/ to each other and are connected by a line running through the centre of the Earth. Such points are as far away from each other as possible, in the Northern Hemisphere, the Antipodes may be used to refer to Australia and New Zealand, and Antipodeans to their inhabitants. Geographically the antipodes of Britain and Ireland are in the Pacific Ocean and this gave rise to the name of the Antipodes Islands of New Zealand, which are close to the antipode of London at about 50°S 179°E. The antipodes of Australia are in the North Atlantic Ocean, while parts of Spain, Portugal, approximately 15% of land territory is antipodal to other land, representing approximately 4. 4% of the Earths surface. The antipode of any place on the Earth is the place that is diametrically opposite it, so a line drawn from the one to the passes through the centre of the Earth. For example, the antipodes of New Zealands lower North Island lie in Spain, most of the Earths land surfaces have ocean at their antipodes, this being a consequence of most land being in the land hemisphere. The singular antipode is a back-formation from the plural antipodes, which in Greek is the plural of the singular antipous, sunrise and sunset do not quite oppose each other at antipodes due to refraction of sunlight. If the geographic coordinates of a point on the Earths surface are and this relation holds true whether the Earth is approximated as a perfect sphere or as a reference ellipsoid. For example, the antipode of the point in China at 37° N 119° E is the point in Argentina at 37° S 61° W, the word antipodes comes from the Greek, ἀντίποδες, plural of antipous, with feet opposite, from anti- opposed and pous foot. Medieval illustrations imagine them in some way inverted, with their growing out of their heads. From the time of St Augustine, the Christian church was skeptical of the notion. In 748, in reply to a letter from Saint Boniface, Pope Zachary declared the belief that beneath the earth there was another world and other men, another sun, in his letter, Boniface had apparently maintained that Vergilius of Salzburg held such a belief. The antipodes being an attribute of a spherical Earth, some ancient authors used their perceived absurdity as an argument for a flat Earth and this posed the problem that Christ told the apostles to evangelize all mankind, with regard to the unreachable antipodes, this would have been impossible. Christ would either have appeared a second time, in the antipodes, such an argument was forwarded by the Spanish theologian Alonso Tostado as late as the 15th century and St. Augustine doubts was a response to Columbuss proposal to sail westwards to the Indies. The author of the Norwegian book Konungs Skuggsjá, from around 1250 and he notes that they will see the sun in the north in the middle of the day and that they will have seasons opposite those of the Northern Hemisphere. The earliest surviving account by a European who had visited the Southern Hemisphere is that of Marco Polo and he noted that it was impossible to see the star Polaris from there. The idea of dry land in the southern climes, the Terra Australis, was introduced by Ptolemy, there are no non-stop scheduled flights between any two antipodal locations by commercial airline service—or anything even close

Gemma Augustea
–
The Gemma Augustea is a low-relief cameo engraved gem cut from a double-layered Arabian onyx stone. It is commonly agreed that the gem cutter who created the Gemma Augustea was either Dioscurides or one of his disciples, the Gemma Augustea is a low-relief cameo engraved gem cut from a double-layered Arabian onyx stone. One layer is white, while the other is bluish-brown, the painstaking method by which the stone was cut allowed minute detail with sharp contrast between the images and background, also allowing for a great deal of shadow play. The size of the gem also made for easier manipulation and a grander scene and it stands 7.5 inches tall with a width of 9 inches and an average thickness of 0.5 inches. It is commonly agreed that the gem cutter who created Gemma Augustea was either Dioscurides or one of his disciples, Dioscurides was Caesar Augustus’ favorite gem cutter, and his work and copies of it are seen from all over the ancient Roman world. The gem is set as though in the period c, AD 10–20, although some scholars believe it to have been created decades later because of their interpretation of the scene. If Dioscurides, or cutters following his example, made it, at some time in antiquity it moved to Byzantium, perhaps after Constantine I had officially moved the capital of the empire there. If this gem was made during his lifetime, it would perhaps have been made as a gift to a family in a Roman province or client kingdom. Alternatively, if the gem was made after Augustus’ death, the identity of one or more of the portraits may be different from the usual identification. Another viewpoint is that the gem does portray Augustus as a god in his lifetime, similar issues arise with other Imperial cameos such as the Blacas Cameo in the British Museum. In 1533, Francis I of France appropriated it and moved it to Paris, not long thereafter it was sold for 12,000 ducats to Rudolph II, Holy Roman Emperor. During the 17th century, it was set in German gold and this setting shows that the gem must have been damaged, the upper left side being broken with at least one other figure missing, probably before Rudolph II bought it, but definitely before 1700. The gem is now in the Kunsthistorisches Museum in Vienna, the throned figure, #1 in the numbered illustration, is usually taken to be Augustus, although in some interpretations, it could represent a later Roman ruler. Figure #3 is the most readily identifiable, having characteristics held by no other, the woman is Oikoumene - the personification of the inhabited world. This inhabited or civilized world is either that of the early Roman Empire and she wears upon her head a mural crown and veil. She is crowning figure #1 with the corona civica of oak leaves - used to someone for saving the life of a Roman citizen. In this grand scale depiction, however, it is given to figure #1 because he saved a multitude of Roman citizens, Figure #5 and #6 seem to be closely related. Figure #5 is Oceanus or Neptune whose significance is often seen as one balancing the scene across from #4 and #7, below him is a reclined personification of either Gaia or Italia Turrita

Augustus
–
Augustus was the founder of the Roman Principate and considered the first Roman emperor, controlling the Roman Empire from 27 BC until his death in AD14. He was born Gaius Octavius into an old and wealthy equestrian branch of the plebeian gens Octavia and his maternal great-uncle Julius Caesar was assassinated in 44 BC, and Octavius was named in Caesars will as his adopted son and heir, then known as Octavianus. He, Mark Antony, and Marcus Lepidus formed the Second Triumvirate to defeat the assassins of Caesar, following their victory at the Battle of Philippi, the Triumvirate divided the Roman Republic among themselves and ruled as military dictators. The Triumvate was eventually torn apart by the ambitions of its members. Lepidus was driven into exile and stripped of his position, in reality, however, he retained his autocratic power over the Republic as a military dictator. By law, Augustus held a collection of powers granted to him for life by the Senate, including supreme military command, and it took several years for Augustus to develop the framework within which a formally republican state could be led under his sole rule. He rejected monarchical titles, and instead called himself Princeps Civitatis, the resulting constitutional framework became known as the Principate, the first phase of the Roman Empire. The reign of Augustus initiated an era of peace known as the Pax Romana. Augustus dramatically enlarged the Empire, annexing Egypt, Dalmatia, Pannonia, Noricum, and Raetia, expanding possessions in Africa, expanding into Germania, beyond the frontiers, he secured the Empire with a buffer region of client states and made peace with the Parthian Empire through diplomacy. Augustus died in AD14 at the age of 75 and he probably died from natural causes, although there were unconfirmed rumors that his wife Livia poisoned him. He was succeeded as Emperor by his adopted son Tiberius, Augustus was known by many names throughout his life, At birth, he was named Gaius Octavius after his biological father. Historians typically refer to him simply as Octavius between his birth in 63 until his adoption by Julius Caesar in 44 BC, upon his adoption, he took Caesars name and became Gaius Julius Caesar Octavianus in accordance with Roman adoption naming standards. He quickly dropped Octavianus from his name, and his contemporaries referred to him as Caesar during this period, historians. In 27 BC, following his defeat of Mark Antony and Cleopatra and it is the events of 27 BC from which he obtained his traditional name of Augustus, which historians use in reference to him from 27 BC until his death in AD14. While his paternal family was from the town of Velletri, approximately 40 kilometres from Rome and he was born at Ox Head, a small property on the Palatine Hill, very close to the Roman Forum. He was given the name Gaius Octavius Thurinus, his cognomen possibly commemorating his fathers victory at Thurii over a band of slaves. Due to the nature of Rome at the time, Octavius was taken to his fathers home village at Velletri to be raised. Octavius only mentions his fathers equestrian family briefly in his memoirs and his paternal great-grandfather Gaius Octavius was a military tribune in Sicily during the Second Punic War

First Council of Nicaea
–
The First Council of Nicaea was a council of Christian bishops convened in the Bithynian city of Nicaea by the Roman Emperor Constantine I in AD325. Constantine I organized the Council along the lines of the Roman Senate and presided over it and this ecumenical council was the first effort to attain consensus in the Church through an assembly representing all of Christendom. Hosius of Cordoba, who was one of the Papal legates. The First Council of Nicaea was the first ecumenical council of the Church, St. Alexander of Alexandria and Athanasius took the first position, the popular presbyter Arius, from whom the term Arianism comes, took the second. The council decided against the Arians overwhelmingly, through it a precedent was set for subsequent general councils to adopt creeds and canons. This council is considered the beginning of the period of the First seven Ecumenical Councils in the History of Christianity. The First Council of Nicaea was convened by Emperor Constantine the Great upon the recommendations of a synod led by Hosius of Córdoba in the Eastertide of 325 and this synod had been charged with investigation of the trouble brought about by the Arian controversy in the Greek-speaking east. To most bishops, the teachings of Arius were heretical and dangerous to the salvation of souls and this was the first general council in the history of the Church summoned by emperor Constantine I. In the Council of Nicaea, The Church had taken her first great step to define revealed doctrine more precisely in response to a challenge from a heretical theology. Constantine had invited all 1,800 bishops of the Christian church within the Roman Empire, Eusebius of Caesarea counted more than 250, Athanasius of Alexandria counted 318, and Eustathius of Antioch estimated about 270. Later, Socrates Scholasticus recorded more than 300, and Evagrius, Hilary of Poitiers, Jerome, Dionysius Exiguus and this number 318 is preserved in the liturgies of the Eastern Orthodox Church and the Coptic Orthodox Church of Alexandria. Delegates came from every region of the Roman Empire, including Britain, the participating bishops were given free travel to and from their episcopal sees to the council, as well as lodging. These bishops did not travel alone, each one had permission to bring him two priests and three deacons, so the total number of attendees could have been above 1,800. Eusebius speaks of an almost innumerable host of accompanying priests, deacons, the Eastern bishops formed the great majority. Of these, the first rank was held by the three patriarchs, Alexander of Alexandria, Eustathius of Antioch, and Macarius of Jerusalem and this position is supported by patristic scholar Timothy Barnes in his book Constantine and Eusebius. Historically, the influence of these marred confessors has been seen as substantial, Athanasius of Alexandria, a young deacon and companion of Bishop Alexander of Alexandria, was among the assistants. Athanasius eventually spent most of his life battling against Arianism, Alexander of Constantinople, then a presbyter, was also present as representative of his aged bishop. The supporters of Arius included Secundus of Ptolemais, Theonus of Marmarica, Zphyrius, other supporters included Eusebius of Nicomedia, Paulinus of Tyrus, Actius of Lydda, Menophantus of Ephesus, and Theognus of Nicaea

Christianity
–
Christianity is a Abrahamic monotheistic religion based on the life and teachings of Jesus Christ, who serves as the focal point for the religion. It is the worlds largest religion, with over 2.4 billion followers, or 33% of the global population, Christians believe that Jesus is the Son of God and the savior of humanity whose coming as the Messiah was prophesied in the Old Testament. Christian theology is summarized in creeds such as the Apostles Creed and his incarnation, earthly ministry, crucifixion, and resurrection are often referred to as the gospel, meaning good news. The term gospel also refers to accounts of Jesuss life and teaching, four of which—Matthew, Mark, Luke. Christianity is an Abrahamic religion that began as a Second Temple Judaic sect in the mid-1st century, following the Age of Discovery, Christianity spread to the Americas, Australasia, sub-Saharan Africa, and the rest of the world through missionary work and colonization. Christianity has played a prominent role in the shaping of Western civilization, throughout its history, Christianity has weathered schisms and theological disputes that have resulted in many distinct churches and denominations. Worldwide, the three largest branches of Christianity are the Catholic Church, the Eastern Orthodox Church, and the denominations of Protestantism. There are many important differences of interpretation and opinion of the Bible, concise doctrinal statements or confessions of religious beliefs are known as creeds. They began as baptismal formulae and were expanded during the Christological controversies of the 4th and 5th centuries to become statements of faith. Many evangelical Protestants reject creeds as definitive statements of faith, even agreeing with some or all of the substance of the creeds. The Baptists have been non-creedal in that they have not sought to establish binding authoritative confessions of faith on one another. Also rejecting creeds are groups with roots in the Restoration Movement, such as the Christian Church, the Evangelical Christian Church in Canada, the Apostles Creed is the most widely accepted statement of the articles of Christian faith. It is also used by Presbyterians, Methodists, and Congregationalists and this particular creed was developed between the 2nd and 9th centuries. Its central doctrines are those of the Trinity and God the Creator, each of the doctrines found in this creed can be traced to statements current in the apostolic period. The creed was used as a summary of Christian doctrine for baptismal candidates in the churches of Rome. Most Christians accept the use of creeds, and subscribe to at least one of the mentioned above. The central tenet of Christianity is the belief in Jesus as the Son of God, Christians believe that Jesus, as the Messiah, was anointed by God as savior of humanity, and hold that Jesus coming was the fulfillment of messianic prophecies of the Old Testament. The Christian concept of the Messiah differs significantly from the contemporary Jewish concept, Jesus, having become fully human, suffered the pains and temptations of a mortal man, but did not sin

Constantine the Great
–
Constantine the Great, also known as Constantine I or Saint Constantine, was a Roman Emperor from 306 to 337 AD. Constantine was the son of Flavius Valerius Constantius, a Roman Army officer and his father became Caesar, the deputy emperor in the west, in 293 AD. Constantine was sent east, where he rose through the ranks to become a military tribune under the emperors Diocletian, in 305, Constantius was raised to the rank of Augustus, senior western emperor, and Constantine was recalled west to campaign under his father in Britannia. As emperor, Constantine enacted many administrative, financial, social, the government was restructured and civil and military authority separated. A new gold coin, the solidus, was introduced to combat inflation and it would become the standard for Byzantine and European currencies for more than a thousand years. He called the First Council of Nicaea in 325, at which the Nicene Creed was adopted by Christians, in military matters, the Roman army was reorganised to consist of mobile field units and garrison soldiers capable of countering internal threats and barbarian invasions. The age of Constantine marked an epoch in the history of the Roman Empire. He built a new residence at Byzantium and renamed the city Constantinople after himself. It would later become the capital of the Empire for over one thousand years and his more immediate political legacy was that, in leaving the empire to his sons, he replaced Diocletians tetrarchy with the principle of dynastic succession. His reputation flourished during the lifetime of his children and centuries after his reign, the medieval church upheld him as a paragon of virtue while secular rulers invoked him as a prototype, a point of reference, and the symbol of imperial legitimacy and identity. Beginning with the Renaissance, there were more critical appraisals of his due to the rediscovery of anti-Constantinian sources. Critics portrayed him as a tyrant, trends in modern and recent scholarship attempted to balance the extremes of previous scholarship. The Church of the Holy Sepulchre, built on his orders at the site of Jesus tomb in Jerusalem. The Papal claim to power in the High Middle Ages was based on the supposed Donation of Constantine. He is venerated as a saint by Eastern Orthodox and Byzantine Catholics, though Constantine has historically often been referred to as the First Christian Emperor, scholars debate his actual beliefs or even his actual comprehension of the Christian faith itself. Constantine was a ruler of major importance, and he has always been a controversial figure, the fluctuations in Constantines reputation reflect the nature of the ancient sources for his reign. These are abundant and detailed, but have strongly influenced by the official propaganda of the period. There are no surviving histories or biographies dealing with Constantines life, the nearest replacement is Eusebius of Caesareas Vita Constantini, a work that is a mixture of eulogy and hagiography

Synod
–
A synod /ˈsɪnəd/ historically is a council of a church, usually convened to decide an issue of doctrine, administration or application. In modern usage, the word refers to the governing body of a particular church. It is also used to refer to a church that is governed by a synod. The word synod comes from the Greek σύνοδος meaning assembly or meeting, originally, synods were meetings of bishops, and the word is still used in that sense in Catholicism and Eastern Orthodoxy. Sometimes the phrase general synod or general council refers to an ecumenical council, the word synod also refers to the standing council of high-ranking bishops governing some of the autocephalous Eastern Orthodox churches. Similarly, the governance of patriarchal and major archiepiscopal Eastern Catholic Churches is entrusted to a permanent synod. The synod in the Western churches is similar, but it is distinguished by being limited to an assembly of bishops. The term is found among those Eastern Orthodox Churches that use a Slavic language, kievan Rus chronicles record the first known East Slavic church sobor as having taken place in Kiev in 1051. Sobors were convened periodically from then on, one notable assembly held in 1415 formed a separate metropoly for the church in the Grand Duchy of Lithuanian lands, such diocesan sobors may be held annually or only occasionally. However, in use, synod and council are applied to specific categories of such meetings. A synod generally meets every three years and is designated an Ordinary General Assembly. However, Extraordinary synods can be called to deal with specific situations, there are also Special synods for the Church in a specific geographic area such as the one held November 16-December 12,1997, for the Church in America. The pope serves as president of an assembly or appoints the president, determines the agenda, and summons, suspends, thereafter they continued by the hundreds into the sixth century. Those authorized by an emperor and often attended by him came to be called ecumenical, today, Council in Roman Catholic canon law typically refers to an irregular meeting of the entire episcopate of a nation, region, or the world for the purpose of legislation with binding force. The pope alone has the right to convoke, suspend, and dissolve an ecumenical council, he presides over it or chooses someone else to do so. The vacancy of the Holy See automatically suspends an ecumenical council, laws or teachings issued by an ecumenical council require the confirmation of the pope, who alone has the right to promulgate them. The role of the pope in a council is a distinct feature of the Catholic Church. Plenary councils, which are meetings of the episcopate of a nation, are convoked by the national episcopal conference
33.
Bishop
–
A bishop is an ordained, consecrated, or appointed member of the Christian clergy who is generally entrusted with a position of authority and oversight. Within these churches, bishops are seen as those who possess the full priesthood, Some Protestant churches including the Lutheran and Methodist churches have bishops serving similar functions as well, though not always understood to be within apostolic succession in the same way. Priests, deacons and lay ministers cooperate and assist their bishop in shepherding a flock, the earliest organization of the Church in Jerusalem was, according to most scholars, similar to that of Jewish synagogues, but it had a council or college of ordained presbyters. In, we see a system of government in Jerusalem chaired by James the Just. In, the Apostle Paul ordains presbyters in churches in Anatolia, in Timothy and Titus in the New Testament a more clearly defined episcopate can be seen. We are told that Paul had left Timothy in Ephesus and Titus in Crete to oversee the local church, Paul commands Titus to ordain presbyters/bishops and to exercise general oversight, telling him to rebuke with all authority. Early sources are unclear but various groups of Christian communities may have had the bishop surrounded by a group or college functioning as leaders of the local churches, eventually, as Christendom grew, bishops no longer directly served individual congregations. Instead, the Metropolitan bishop appointed priests to each congregation. Around the end of the 1st century, the organization became clearer in historical documents. While Ignatius of Antioch offers the earliest clear description of monarchial bishops he is an advocate of monepiscopal structure rather than describing an accepted reality. To the bishops and house churches to which he writes, he offers strategies on how to pressure house churches who dont recognize the bishop into compliance. Other contemporary Christian writers do not describe monarchial bishops, either continuing to equate them with the presbyters or speaking of episkopoi in a city, plainly therefore we ought to regard the bishop as the Lord Himself — Epistle of Ignatius to the Ephesians 6,1. Your godly bishop — Epistle of Ignatius to the Magnesians 2,1, therefore as the Lord did nothing without the Father, either by Himself or by the Apostles, so neither do ye anything without the bishop and the presbyters. — Epistle of Ignatius to the Magnesians 7,1. Be obedient to the bishop and to one another, as Jesus Christ was to the Father, and as the Apostles were to Christ and to the Father, — Epistle of Ignatius to the Magnesians 13,2. Apart from these there is not even the name of a church, — Epistle of Ignatius to the Trallesians 3,1. Follow your bishop, as Jesus Christ followed the Father, and the presbytery as the Apostles, and to the deacons pay respect, as to Gods commandment — Epistle of Ignatius to the Smyrnans 8,1. He that honoureth the bishop is honoured of God, he that doeth aught without the knowledge of the bishop rendereth service to the devil — Epistle of Ignatius to the Smyrnans 9,1

Diocletian
–
Diocletian, born Diocles, was a Roman emperor from 284 to 305. Born to a family of low status in the Roman province of Dalmatia, after the deaths of Carus and his son Numerian on campaign in Persia, Diocletian was proclaimed emperor. The title was claimed by Carus other surviving son, Carinus. Diocletians reign stabilized the empire and marks the end of the Crisis of the Third Century and he appointed fellow officer Maximian as Augustus, co-emperor, in 286. Diocletian delegated further on 1 March 293, appointing Galerius and Constantius as Caesars, under this tetrarchy, or rule of four, each emperor would rule over a quarter-division of the empire. Diocletian secured the borders and purged it of all threats to his power. He defeated the Sarmatians and Carpi during several campaigns between 285 and 299, the Alamanni in 288, and usurpers in Egypt between 297 and 298, Galerius, aided by Diocletian, campaigned successfully against Sassanid Persia, the empires traditional enemy. In 299 he sacked their capital, Ctesiphon, Diocletian led the subsequent negotiations and achieved a lasting and favorable peace. He established new centres in Nicomedia, Mediolanum, Antioch. Building on third-century trends towards absolutism, he styled himself an autocrat, elevating himself above the masses with imposing forms of court ceremonies. Bureaucratic and military growth, constant campaigning, and construction increased the states expenditures. From at least 297 on, imperial taxation was standardized, made more equitable, not all of Diocletians plans were successful, the Edict on Maximum Prices, his attempt to curb inflation via price controls, was counterproductive and quickly ignored. Weakened by illness, Diocletian left the office on 1 May 305. He lived out his retirement in his palace on the Dalmatian coast and his palace eventually became the core of the modern-day city of Split in Croatia. Diocletian was born near Salona in Dalmatia, some time around 244 and his parents gave him the Greek name Diocles, or possibly Diocles Valerius. The modern historian Timothy Barnes takes his official birthday,22 December, other historians are not so certain. Diocles parents were of low status, and writers critical of him claimed that his father was a scribe or a freedman of the senator Anullinus, the first forty years of his life are mostly obscure. The Byzantine chronicler Joannes Zonaras states that he was Dux Moesiae, the often-unreliable Historia Augusta states that he served in Gaul, but this account is not corroborated by other sources and is ignored by modern historians of the period

List of Byzantine emperors
–
This is a list of the Byzantine emperors from the foundation of Constantinople in 330 AD, which marks the conventional start of the Eastern Roman Empire, to its fall to the Ottoman Empire in 1453 AD. Emperors listed below up to Theodosius I in 395 were sole or joint rulers of the entire Roman Empire, the Byzantine Empire was the direct legal continuation of the eastern half of the Roman Empire following the division of the Roman Empire in 395. All Byzantine emperors considered themselves to be the rightful Roman emperor in direct succession from Augustus, the title of all Emperors preceding Heraclius was officially Augustus, although other titles such as Dominus were also used. Their names were preceded by Imperator Caesar and followed by Augustus, following Heraclius, the title commonly became the Greek Basileus, which had formerly meant sovereign but was then used in place of Augustus. Following the establishment of the rival Holy Roman Empire in Western Europe, in later centuries, the Emperor could be referred to by Western Christians as the Emperor of the Greeks. Towards the end of the Empire, the standard formula of the Byzantine ruler was in Christ, Emperor.

Constantinople
–
Constantinople was the capital city of the Roman/Byzantine Empire, and also of the brief Latin, and the later Ottoman empires. It was reinaugurated in 324 AD from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, Constantinople was famed for its massive and complex defences. The first wall of the city was erected by Constantine I, Constantinople never truly recovered from the devastation of the Fourth Crusade and the decades of misrule by the Latins. The origins of the name of Byzantion, more known by the later Latin Byzantium, are not entirely clear. The founding myth of the city has it told that the settlement was named after the leader of the Megarian colonists, Byzas. The later Byzantines of Constantinople themselves would maintain that the city was named in honour of two men, Byzas and Antes, though this was likely just a play on the word Byzantion. During this time, the city was also called Second Rome, Eastern Rome, and Roma Constantinopolitana. As the city became the remaining capital of the Roman Empire after the fall of the West, and its wealth, population, and influence grew. In the language of other peoples, Constantinople was referred to just as reverently, the medieval Vikings, who had contacts with the empire through their expansion in eastern Europe used the Old Norse name Miklagarðr, and later Miklagard and Miklagarth. In Arabic, the city was sometimes called Rūmiyyat al-kubra and in Persian as Takht-e Rum, in East and South Slavic languages, including in medieval Russia, Constantinople was referred to as Tsargrad or Carigrad, City of the Caesar, from the Slavonic words tsar and grad. This was presumably a calque on a Greek phrase such as Βασιλέως Πόλις, the modern Turkish name for the city, İstanbul, derives from the Greek phrase eis tin polin, meaning into the city or to the city. In 1928, the Turkish alphabet was changed from Arabic script to Latin script, in time the city came to be known as Istanbul and its variations in most world languages. In Greece today, the city is still called Konstantinoúpolis/Konstantinoúpoli or simply just the City, apart from this, little is known about this initial settlement, except that it was abandoned by the time the Megarian colonists settled the site anew. A farsighted treaty with the emergent power of Rome in c.150 BC which stipulated tribute in exchange for independent status allowed it to enter Roman rule unscathed. The site lay astride the land route from Europe to Asia and the seaway from the Black Sea to the Mediterranean, and had in the Golden Horn an excellent and spacious harbour. He would later rebuild Byzantium towards the end of his reign, in which it would be briefly renamed Augusta Antonina, fortifying it with a new city wall in his name, Constantine had altogether more colourful plans. Rome was too far from the frontiers, and hence from the armies and the imperial courts, yet it had been the capital of the state for over a thousand years, and it might have seemed unthinkable to suggest that the capital be moved to a different location. Constantinople was built over 6 years, and consecrated on 11 May 330, Constantine divided the expanded city, like Rome, into 14 regions, and ornamented it with public works worthy of an imperial metropolis

Ecumenical Patriarch of Constantinople
–
The Ecumenical Patriarchate of Constantinople is one of the most enduring institutions in the world and has had a prominent part in world history. The ecumenical patriarchs in ancient times helped in the spread of Christianity, in the Middle Ages they played a major role in the affairs of the Eastern Orthodox Church, as well as in the politics of the Orthodox world, and in spreading Christianity among the Slavs. Within the five sees of the Pentarchy, the Ecumenical Patriarch is regarded as the successor of Andrew the Apostle. The current holder of the office is Bartholomew I, the 270th holder of the title, in his role as head of the Orthodox Church of Constantinople, he also holds the title Archbishop of Constantinople, New Rome. The see of Byzantium, whose foundation was ascribed to Andrew the Apostle, was originally a common bishopric. It gained importance when Emperor Constantine elevated Byzantium to a second capital alongside Rome, the sees ecclesiastical status as the second of five Patriarchates were developed by the Ecumenical Councils of Constantinople in 381 and Chalcedon in 451. The Turkish government recognizes him as the leader of the Greek minority in Turkey. The Patriarch was subject to the authority of the Ottoman Empire after the conquest of Constantinople in 1453, today, according to Turkish law, he is subject to the authority of the state of Turkey and is required to be a citizen of Turkey to be Patriarch. The Patriarch of Constantinople has been dubbed the Ecumenical Patriarch since the 6th century, the monastic communities of Mount Athos are stauropegic and are directly under the jurisdiction of Ecumenical Patriarch, who is the only bishop with jurisdiction thereover. The Ecumenical Patriarch has a role among Orthodox bishops, though it is not without its controversy. He is primus inter pares, as he is senior among all Orthodox bishops and this primacy, expressed in canonical literature as presbeia, grants to the Ecumenical Patriarch the right to preside at pan-Orthodox synods. Additionally, the literature of the Orthodox Church grants to the Ecumenical Patriarch the right to hear appeals in cases of dispute between bishops. Historically, the Ecumenical Patriarch has heard such appeals and sometimes was invited to intervene in other disputes and difficulties. Even as early as the 4th century, Constantinople was instrumental in the deposition of multiple bishops outside its traditional jurisdiction. This still occurs today, as when in 2006 the patriarchate was invited to assist in declaring the archbishop of the Church of Cyprus incompetent due to his having Alzheimers disease.

That is, his role is one of promoting and sustaining Church unity. Such a title is acceptable if it refers to this unique role, the five patriarchs of the ancient Pentarchy are to be given seniority of honour, but have no actual power over other bishops other than the power of the synod they are chairing
