Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Tiber
–
It drains a basin estimated at 17,375 square kilometres. The river has achieved lasting fame as the watercourse of the city of Rome. The river rises at Mount Fumaiolo in central Italy and flows in a southerly direction past Perugia. However, it does not form a delta, owing to a strong north-flowing sea current close to the shore, to the steep shelving of the coast. The source of the Tiber consists of two springs 10 metres away from each other on Mount Fumaiolo and these springs are called Le Vene. The springs are in a beech forest 1,268 metres above sea level, during the 1930s, Benito Mussolini placed an antique marble Roman column at the point where the river arises, inscribed QUI NASCE IL FIUME SACRO AI DESTINI DI ROMA. There is an eagle on the top of this column, the first miles of the Tiber run through Valtiberina before entering Umbria. It is probable that the genesis of the name Tiber was pre-Latin, like the Roman name of Tibur, the same root is found in the Latin praenomen Tiberius. There are also Etruscan variants of this praenomen in Thefarie and Teperie, the legendary king Tiberinus, ninth in the king-list of Alba Longa, was said to have drowned in the river Albula, which was afterward called Tiberis. Yet another etymology is from *dubri-, water, considered by Alessio as Sicel and this root *dubri- is widespread in Western Europe e. g. Dover, Portus Dubris. According to the legend, Jupiter made him a god and guardian spirit of the river and this gave rise to the standard Roman depiction of the river as a powerfully built reclining god, also named Tiberinus, with streams of water flowing from his hair and beard. The Tiber was also believed to be the river into which Romulus and Remus were thrown as infants, according to legend, the city of Rome was founded in 753 BC on the banks of the Tiber about 25 kilometres from the sea at Ostia. The island Isola Tiberina in the centre of Rome, between Trastevere and the ancient center, was the site of an important ancient ford and was later bridged. Legend says Romes founders, the twin brothers Romulus and Remus, were abandoned on its waters, the river marked the boundary between the lands of the Etruscans to the west, the Sabines to the east and the Latins to the south. Benito Mussolini, born in Romagna, adjusted the boundary between Tuscany and Emilia-Romagna, so that the springs of the Tiber would lie in Romagna and it was later used to ship stone, timber and foodstuffs to Rome. During the Punic Wars of the 3rd century BC, the harbour at Ostia became a key naval base and it later became Romes most important port, where wheat, olive oil, and wine were imported from Romes colonies around the Mediterranean. Wharves were also built along the riverside in Rome itself, lining the riverbanks around the Campus Martius area, the Romans connected the river with a sewer system and with an underground network of tunnels and other channels, to bring its water into the middle of the city. Wealthy Romans had garden-parks or horti on the banks of the river in Rome up through the first century BC and these may have been sold and developed about a century later

Rome
–
Rome is a special comune and the capital of Italy. Rome also serves as the capital of the Lazio region, with 2,873,598 residents in 1,285 km2, it is also the countrys largest and most populated comune and fourth-most populous city in the European Union by population within city limits. It is the center of the Metropolitan City of Rome, which has a population of 4.3 million residents, the city is located in the central-western portion of the Italian Peninsula, within Lazio, along the shores of the Tiber. Romes history spans more than 2,500 years, while Roman mythology dates the founding of Rome at only around 753 BC, the site has been inhabited for much longer, making it one of the oldest continuously occupied sites in Europe. The citys early population originated from a mix of Latins, Etruscans and it was first called The Eternal City by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called the Caput Mundi, due to that, Rome became first one of the major centres of the Italian Renaissance, and then the birthplace of both the Baroque style and Neoclassicism. Famous artists, painters, sculptors and architects made Rome the centre of their activity, in 1871 Rome became the capital of the Kingdom of Italy, and in 1946 that of the Italian Republic. Rome has the status of a global city, Rome ranked in 2014 as the 14th-most-visited city in the world, 3rd most visited in the European Union, and the most popular tourist attraction in Italy. Its historic centre is listed by UNESCO as a World Heritage Site, monuments and museums such as the Vatican Museums and the Colosseum are among the worlds most visited tourist destinations with both locations receiving millions of tourists a year. Rome hosted the 1960 Summer Olympics and is the seat of United Nations Food, however, it is a possibility that the name Romulus was actually derived from Rome itself. As early as the 4th century, there have been alternate theories proposed on the origin of the name Roma. There is archaeological evidence of occupation of the Rome area from approximately 14,000 years ago. Evidence of stone tools, pottery and stone weapons attest to about 10,000 years of human presence, several excavations support the view that Rome grew from pastoral settlements on the Palatine Hill built above the area of the future Roman Forum. Between the end of the age and the beginning of the Iron age. However, none of them had yet an urban quality, nowadays, there is a wide consensus that the city was gradually born through the aggregation of several villages around the largest one, placed above the Palatine. All these happenings, which according to the excavations took place more or less around the mid of the 8th century BC. Despite recent excavations at the Palatine hill, the view that Rome has been indeed founded with an act of will as the legend suggests in the middle of the 8th century BC remains a fringe hypothesis. Traditional stories handed down by the ancient Romans themselves explain the earliest history of their city in terms of legend and myth

Italy
–
Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino, Italy covers an area of 301,338 km2 and has a largely temperate seasonal climate and Mediterranean climate. Due to its shape, it is referred to in Italy as lo Stivale. With 61 million inhabitants, it is the fourth most populous EU member state, the Italic tribe known as the Latins formed the Roman Kingdom, which eventually became a republic that conquered and assimilated other nearby civilisations. The legacy of the Roman Empire is widespread and can be observed in the distribution of civilian law, republican governments, Christianity. The Renaissance began in Italy and spread to the rest of Europe, bringing a renewed interest in humanism, science, exploration, Italian culture flourished at this time, producing famous scholars, artists and polymaths such as Leonardo da Vinci, Galileo, Michelangelo and Machiavelli. The weakened sovereigns soon fell victim to conquest by European powers such as France, Spain and Austria. Despite being one of the victors in World War I, Italy entered a period of economic crisis and social turmoil. The subsequent participation in World War II on the Axis side ended in defeat, economic destruction. Today, Italy has the third largest economy in the Eurozone and it has a very high level of human development and is ranked sixth in the world for life expectancy. The country plays a prominent role in regional and global economic, military, cultural and diplomatic affairs, as a reflection of its cultural wealth, Italy is home to 51 World Heritage Sites, the most in the world, and is the fifth most visited country. The assumptions on the etymology of the name Italia are very numerous, according to one of the more common explanations, the term Italia, from Latin, Italia, was borrowed through Greek from the Oscan Víteliú, meaning land of young cattle. The bull was a symbol of the southern Italic tribes and was often depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus, mentioned also by Aristotle and Thucydides. The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, but by his time Oenotria and Italy had become synonymous, and the name also applied to most of Lucania as well. The Greeks gradually came to apply the name Italia to a larger region, excavations throughout Italy revealed a Neanderthal presence dating back to the Palaeolithic period, some 200,000 years ago, modern Humans arrived about 40,000 years ago. Other ancient Italian peoples of undetermined language families but of possible origins include the Rhaetian people and Cammuni. Also the Phoenicians established colonies on the coasts of Sardinia and Sicily, the Roman legacy has deeply influenced the Western civilisation, shaping most of the modern world

Arch bridge
–
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, a viaduct may be made from a series of arches, although other more economical structures are typically used today. Possibly the oldest existing bridge is the Mycenaean Arkadiko bridge in Greece from about 1300 BC. The stone corbel arch bridge is used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch, a more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly of stone, in as many as 26 different countries. Roman arch bridges were usually semicircular, although a number were segmental arch bridges, generally, Roman bridges featured wedge-shaped primary arch stones of the same in size and shape. The Romans built both single spans and lengthy multiple arch aqueducts, such as the Pont du Gard and Segovia Aqueduct. Their bridges featured from an early time onwards flood openings in the piers, e. g. in the Pons Fabricius in Rome, Roman engineers were the first and until the industrial revolution the only ones to construct bridges with concrete, which they called Opus caementicium. The outside was covered with brick or ashlar, as in the Alcántara bridge. The Romans also introduced segmental arch bridges into bridge construction, trajans bridge over the Danube featured open-spandrel segmental arches made of wood. This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m long Puente Romano at Mérida. The late Roman Karamagara Bridge in Cappadocia may represent the earliest surviving bridge featuring a pointed arch, in medieval Europe, bridge builders improved on the Roman structures by using narrower piers, thinner arch barrels and lower span-rise ratios on bridges. Gothic pointed arches were introduced, reducing lateral thrust. The 14th century in particular saw bridge building reaching new heights, the bridge at Trezzo sullAdda, destroyed in the 15th century, even featured a span length of 72 m, not matched until 1796. Constructions such as the acclaimed Florentine segmental arch bridge Ponte Vecchio combined sound engineering with aesthetical appeal, the three elegant arches of the Renaissance Ponte Santa Trinita constitute the oldest elliptic arch bridge worldwide. In China, the oldest existing bridge is the Zhaozhou Bridge of 605 AD. The Zhaozhou Bridge, with a length of 167 feet and span of 123 feet, is the worlds first wholly stone open-spandrel segmental arch bridge, Bridges with perforated spandrels can be found worldwide, such as in China

Giovanni Battista Piranesi
–
Giovanni Battista Piranesi was an Italian artist famous for his etchings of Rome and of fictitious and atmospheric prisons. Piranesi was born in Mogliano Veneto, near Treviso, then part of the Republic of Venice, from 1740 he had an opportunity to work in Rome as a draughtsman for Marco Foscarini, the Venetian ambassador of the new Pope Benedict XIV. He resided in the Palazzo Venezia and studied under Giuseppe Vasi, Giuseppe Vasi found Piranesis talent was beyond engraving. According to Legrand, Vasi told Piranesi that you are too much of a painter, my friend, from 1743 to 1747 he sojourned mainly in Venice where, according to some sources, he often visited Giovanni Battista Tiepolo, a leading artist in Venice. It was Tiepolo who expanded the restrictive conventions of reproductive, topographical and he then returned to Rome, where he opened a workshop in Via del Corso. In 1748–1774 he created a series of vedute of the city which established his fame. In the meantime Piranesi devoted himself to the measurement of many of the ancient edifices, in 1761 he became a member of the Accademia di San Luca and opened a printing facility of his own. In 1762 the Campo Marzio dellantica Roma collection of engravings was printed, the following year he was commissioned by Pope Clement XIII to restore the choir of San Giovanni in Laterano, but the work did not materialize. He combined certain ancient architectural elements, trophies and escutcheons, with a venetian whimsicality for the facade of the church and this was the only time he expressed himself in actual marble and stone. In 1767 he was made a knight of the Golden Spur, in 1776 he created his best known work as a restorer of ancient sculpture, the Piranesi Vase, and in 1777–78 he published Avanzi degli Edifici di Pesto. He died in Rome in 1778 after an illness, and was buried in the Church he had helped restore. His tomb was designed by Giuseppi Angelini, the idea of Enlightenment by theorists and artists traveled all over the Europe including Paris, Dresden, and London. The developing center of the Grand Tour was Rome, Rome became a new meeting place and intellectual capital of Europe for the leaders of a new movement in the arts. The city was attracting artists and architects all over the Europe beside the Grand Tourists, dealers. While many came though official institutions such as the French Academy, others came to see the new discoveries at Heraculaneum, Piranesi was not only aware of the engineering of the ancient buildings but also the poetic aspects of the ruins from his experience in Venice. One distinctive feature of Piranesis work is based on the interpretation of Classical antiquity by adding his imagination to increase the originality, through the works of Marco Ricci and particularly Giovanini Paolo Pannini, Piranesi became familiar with the architectonic values as well as the ruin fantasy. The remains of Rome kindled Piranesis enthusiasm, some of his later work was completed by his children and several pupils. Piranesis son and coadjutor, Francesco, collected and preserved his plates, twenty-nine folio volumes containing about 2000 prints appeared in Paris

Italian language
–
By most measures, Italian, together with Sardinian, is the closest to Latin of the Romance languages. Italian is a language in Italy, Switzerland, San Marino, Vatican City. Italian is spoken by minorities in places such as France, Montenegro, Bosnia & Herzegovina, Crimea and Tunisia and by large expatriate communities in the Americas. Many speakers are native bilinguals of both standardized Italian and other regional languages, Italian is the fourth most studied language in the world. Italian is a major European language, being one of the languages of the Organisation for Security and Cooperation in Europe. It is the third most widely spoken first language in the European Union with 65 million native speakers, including Italian speakers in non-EU European countries and on other continents, the total number of speakers is around 85 million. Italian is the working language of the Holy See, serving as the lingua franca in the Roman Catholic hierarchy as well as the official language of the Sovereign Military Order of Malta. Italian is known as the language of music because of its use in musical terminology and its influence is also widespread in the arts and in the luxury goods market. Italian has been reported as the fourth or fifth most frequently taught foreign language in the world, Italian was adopted by the state after the Unification of Italy, having previously been a literary language based on Tuscan as spoken mostly by the upper class of Florentine society. Its development was influenced by other Italian languages and to some minor extent. Its vowels are the second-closest to Latin after Sardinian, unlike most other Romance languages, Italian retains Latins contrast between short and long consonants. As in most Romance languages, stress is distinctive, however, Italian as a language used in Italy and some surrounding regions has a longer history. What would come to be thought of as Italian was first formalized in the early 14th century through the works of Tuscan writer Dante Alighieri, written in his native Florentine. Dante is still credited with standardizing the Italian language, and thus the dialect of Florence became the basis for what would become the language of Italy. Italian was also one of the recognised languages in the Austro-Hungarian Empire. Italy has always had a dialect for each city, because the cities. Those dialects now have considerable variety, as Tuscan-derived Italian came to be used throughout Italy, features of local speech were naturally adopted, producing various versions of Regional Italian. Even in the case of Northern Italian languages, however, scholars are not to overstate the effects of outsiders on the natural indigenous developments of the languages

Latin
–
Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, Latin was originally spoken in Latium, in the Italian Peninsula. Through the power of the Roman Republic, it became the dominant language, Vulgar Latin developed into the Romance languages, such as Italian, Portuguese, Spanish, French, and Romanian. Latin, Italian and French have contributed many words to the English language, Latin and Ancient Greek roots are used in theology, biology, and medicine. By the late Roman Republic, Old Latin had been standardised into Classical Latin, Vulgar Latin was the colloquial form spoken during the same time and attested in inscriptions and the works of comic playwrights like Plautus and Terence. Late Latin is the language from the 3rd century. Later, Early Modern Latin and Modern Latin evolved, Latin was used as the language of international communication, scholarship, and science until well into the 18th century, when it began to be supplanted by vernaculars. Ecclesiastical Latin remains the language of the Holy See and the Roman Rite of the Catholic Church. Today, many students, scholars and members of the Catholic clergy speak Latin fluently and it is taught in primary, secondary and postsecondary educational institutions around the world. The language has been passed down through various forms, some inscriptions have been published in an internationally agreed, monumental, multivolume series, the Corpus Inscriptionum Latinarum. Authors and publishers vary, but the format is about the same, volumes detailing inscriptions with a critical apparatus stating the provenance, the reading and interpretation of these inscriptions is the subject matter of the field of epigraphy. The works of several hundred ancient authors who wrote in Latin have survived in whole or in part and they are in part the subject matter of the field of classics. The Cat in the Hat, and a book of fairy tales, additional resources include phrasebooks and resources for rendering everyday phrases and concepts into Latin, such as Meissners Latin Phrasebook. The Latin influence in English has been significant at all stages of its insular development. From the 16th to the 18th centuries, English writers cobbled together huge numbers of new words from Latin and Greek words, dubbed inkhorn terms, as if they had spilled from a pot of ink. Many of these words were used once by the author and then forgotten, many of the most common polysyllabic English words are of Latin origin through the medium of Old French. Romance words make respectively 59%, 20% and 14% of English, German and those figures can rise dramatically when only non-compound and non-derived words are included. Accordingly, Romance words make roughly 35% of the vocabulary of Dutch, Roman engineering had the same effect on scientific terminology as a whole

Battle of the Milvian Bridge
–
The Battle of the Milvian Bridge took place between the Roman Emperors Constantine I and Maxentius on October 28,312. It takes its name from the Milvian Bridge, an important route over the Tiber, Constantine won the battle and started on the path that led him to end the Tetrarchy and become the sole ruler of the Roman Empire. Maxentius drowned in the Tiber during the battle and his body was taken from the river. According to chroniclers such as Eusebius of Caesarea and Lactantius, the battle marked the beginning of Constantines conversion to Christianity, Eusebius of Caesarea recounts that Constantine and his soldiers had a vision sent by the Christian God. This was interpreted as a promise of victory if the sign of the Chi-Rho, the underlying causes of the battle were the rivalries inherent in Diocletians Tetrarchy. After Diocletian stepped down on 1 May 305, his successors began to struggle for control of the Roman Empire almost immediately, although Constantine was the son of the Western Emperor Constantius, the Tetrarchic ideology did not necessarily provide for hereditary succession. When Constantius died on 25 July 306, his fathers troops proclaimed Constantine as Augustus in Eboracum, in Rome, the favorite was Maxentius, the son of Constantius imperial colleague Maximian, who seized the title of emperor on 28 October 306. But whereas Constantines claim was recognized by Galerius, ruler of the Eastern provinces, Galerius, however, recognized Constantine as holding only the lesser imperial rank of Caesar. Galerius ordered his co-Augustus, Severus, to put Maxentius down in early 307, once Severus arrived in Italy, however, his army defected to Maxentius. Severus was captured, imprisoned, and executed, Galerius himself marched on Rome in the autumn, but failed to take the city. Constantine avoided conflict with both Maxentius and the Eastern emperors for most of this period, by 312, however, Constantine and Maxentius were engaged in open hostility with one another, although they were brothers-in‑law through Constantines marriage to Fausta, sister of Maxentius. In the spring of 312, Constantine gathered his forces and decided to oust Maxentius himself. He easily overran northern Italy, winning two battles, the first near Turin, the second at Verona, where the praetorian prefect Ruricius Pompeianus, Maxentius most senior general, was killed. It is commonly understood that on the evening of 27 October with the armies preparing for battle, some details of that vision, however, differ between the sources reporting it. Lactantius states that, in the night before the battle, Constantine was commanded in a dream to delineate the heavenly sign on the shields of his soldiers and he followed the commands of his dream and marked the shields with a sign denoting Christ. Lactantius describes that sign as a staurogram, or a Latin cross with its upper end rounded in a P-like fashion, there is no certain evidence that Constantine ever used that sign, opposed to the better known Chi-Rho sign described by Eusebius. From Eusebius, two accounts of the battle survive, the first, shorter one in the Ecclesiastical History promotes the belief that God helped Constantine but does not mention any vision. In his later Life of Constantine, Eusebius gives an account of a vision

Consul
–
Consul was the title of one of the chief magistrates of the Roman Republic, and subsequently a somewhat significant title under the Roman Empire. The title was used in other city states and also revived in modern states. The relating adjective is consular, from the consularis, in modern terminology, a consul is a type of diplomat. The American Heritage Dictionary defines consul as an appointed by a government to reside in a foreign country. Throughout most of southern France, a consul was an equivalent to the échevins of the north. The most prominent were those of Bordeaux and Toulouse, which came to be known as jurats and capitouls, the capitouls of Toulouse were granted transmittable nobility. In many other towns the first consul, was the equivalent of a mayor today, assisted by a variable number of secondary consuls. His main task was to levy and collect tax, the Dukes of Gaeta often used also the title of consul in its Greek form Hypatos. The city-state of Genoa, unlike ancient Rome, bestowed the title of consul on various state officials, among these were Genoese officials stationed in various Mediterranean ports, whose role included helping Genoese merchants and sailors in difficulties with the local authorities. This institution, with its name, was emulated by other powers and is reflected in the modern usage of the word. In reality, the first consul, Bonaparte, dominated his two colleagues and held power, soon making himself consul for life and eventually, in 1804. Chief magistrate, an office held for four months by one of the consuls. As noted above, Bologna already had consuls at some parts of its Medieval history, while many cities had a double-headed chief magistracy, often another title was used, such as Duumvir or native styles such as Meddix, but consul was used in some. It was not uncommon for an organization under Roman private law to copy the terminology of state, the founding statute, or contract, of such an organisation was called lex, law. The people elected each year were patricians, members of the upper class. org, see each present country
