The history of geography includes many histories of geography which have differed over time and between different cultural and political groups. In more recent developments, geography has become a distinct academic discipline. 'Geography' derives from the Greek – geographia, literally "Earth-writing", that is, description or writing about the Earth. The first person to use the word geography was Eratosthenes (276–194 BC). However, there is evidence for recognizable practices of geography, such as cartography (map-making), prior to the use of the term. Egypt The known world of Ancient Egypt saw the Nile as the center, and the world as based upon "the" river. Various oases were known to the east and west, and were considered locations of various gods (e.g. Siwa, for Amon). To the South lay the Kushitic region, known as far as the 4th cataract. Punt was a region south along the shores of the Red Sea. Various Asiatic peoples were known as Retenu, Kanaan, Que, Harranu, or Khatti (Hittites). At various times especially in the Late Bronze Age Egyptians had diplomatic and trade relationships with Babylonia and Elam. The Mediterranean was called "the Great Green" and was believed to be part of a world encircling ocean. Europe was unknown although may have become part of the Egyptian world view in Phoenician times. To the west of Asia lay the realms of Keftiu, possibly Crete, and Mycenae (thought to be part of a chain of islands, that joined Cyprus, Crete, Sicily and later perhaps Sardinia, Corsica and the Balearics to Africa). Babylon The oldest known world maps date back to ancient Babylon from the 9th century BC. The best known Babylonian world map, however, is the Imago Mundi of 600 BC. The map as reconstructed by Eckhard Unger shows Babylon on the Euphrates, surrounded by a circular landmass showing Assyria, Urartu and several cities, in turn surrounded by a "bitter river" (Oceanus), with seven islands arranged around it so as to form a seven-pointed star. The accompanying text mentions seven outer regions beyond the encircling ocean. The descriptions of five of them have survived. In contrast to the Imago Mundi, an earlier Babylonian world map dating back to the 9th century BC depicted Babylon as being further north from the center of the world, though it is not certain what that center was supposed to represent. Greco-Roman world The ancient Greeks view Homer as the founder of geography. His
