Geography (Ptolemy)

The Geography known by its Latin names as the Geographia and the Cosmographia, is a gazetteer, an atlas, a treatise on cartography, compiling the geographical knowledge of the 2nd-century Roman Empire. Written by Claudius Ptolemy in Greek at Alexandria around AD 150, the work was a revision of a now-lost atlas by Marinus of Tyre using additional Roman and Persian gazetteers and new principles, its translation into Arabic in the 9th century and Latin in 1406 was influential on the geographical knowledge and cartographic traditions of the medieval Caliphate and Renaissance Europe. Versions of Ptolemy's work in antiquity were proper atlases with attached maps, although some scholars believe that the references to maps in the text were additions. No Greek manuscript of the Geography survives from earlier than the 13th century. A letter written by the Byzantine monk Maximus Planudes records that he searched for one for Chora Monastery in the summer of 1295. In Europe, maps were sometimes redrawn using the coordinates provided by the text, as Planudes was forced to do.

Scribes and publishers could 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 Planudes's work; the first Latin translation of these texts was made in 1406 or 1407 by Jacobus Angelus in Florence, under the name Geographia Claudii Ptolemaei. It is not thought that his edition had maps, although Manuel Chrysoloras had given Palla Strozzi a Greek copy of Planudes's 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 and arrange Ptolemy's data. 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, which were intended to be used as captions to clarify the map's contents and maintain their accuracy during copying. 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, he provided instructions on. The gazetteer section of Ptolemy's work provided latitude and longitude coordinates for all the places and geographical features in the work. Latitude was expressed in degrees of arc from the equator, the same system, used now, though Ptolemy used fractions of a degree rather than minutes of arc, 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. Ptolemy's work included a single large and less detailed world map and separate and more detailed regional maps.

The first Greek manuscripts compiled after Maximus Planudes's rediscovery of the text had as many as 64 regional maps. The standard set in Western Europe came to be 26: 10 European maps, 4 African maps, 12 Asian maps; as early as the 1420s, these canonical maps were complemented by extra-Ptolemaic regional maps depicting, e.g. Scandinavia; the original treatise by Marinus of Tyre that formed the basis of Ptolemy's Geography has been 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 Ptolemy's Geography and used it as the basis of his Chorography of the Ecumene. Imperial writers and mathematicians, seem to have restricted themselves to commenting on Ptolemy's text, rather than improving upon it. Byzantine scholars continued these geographical traditions throughout the Medieval period. Whereas previous Greco-Roman geographers such as Strabo and Pliny the Elder demonstrated a reluctance to rely on the contemporary accounts of sailors and merchants who plied distant areas of the Indian Ocean and Ptolemy betray a much greater receptiveness to incorporating information received from them.

For instance, Grant Parker argues that it would be implausible for them to have constructed the Bay of Bengal as as they did without the accounts of sailors. When it comes to the account of the Golden Chersonese and the Magnus Sinus and Ptolemy relied on the testimony of a Greek sailor named Alexandros, who claimed to have visited a far eastern site called "Cattigara". Muslim cartographers were using Geography by the 9th century. At that time, in the court of the caliph al-Maʾmūm, al-Khwārazmī compiled his Book of the Depiction of the Earth which mimicked the Geography in providing the coordinates for 545 cities and regional maps of the Nile, the Island of the Jewel, the Sea of Darkness, the Sea of Azov.

Group of Eight (Australian universities)

The Group of Eight is a coalition of world-leading research intensive Australian universities. The Go8 universities are some of the largest and the oldest universities in Australia and are the highest ranked of all Australian universities. In 2016 all Go8 Universities were ranked in the top 150 worldwide, with six in the top 100. Go8 Universities feature in the top 100 places for every subject area in the QS world university subject rankings. All Go8 Universities are in the QS top 100 for literature, biological sciences, environmental sciences and finance, anthropology and education; the Go8 Board, which consists of the vice-chancellors of its eight member universities, meets five times a year. The current Chair of the Board is Professor Ian Jacobs, Vice-Chancellor, University of New South Wales. Ms Vicki Thomson is the Chief Executive of the Group of Eight, taking up the role in January 2015. According to the Department of Education and Workplace Relations, in 2008 the Group of Eight universities received twice as much research funding as the other 31 Australian universities combined.
