History of geography

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 γεωγραφία – geographia, a literal translation of which would be 'to describe or write 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 (or map-making) prior to the use of the term geography.No matter where one goes in India, one will find a landscape in which mountains, rivers, forests, and villages are elaborately linked to the stories and gods of Indian culture. Every place in this vast country has its story; and conversely, every story of Hindu myth and legend has its place.

The known world of Ancient Egypt saw the Nile as the centre, 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)12 . 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 Balarics to Africa). 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. The ancient Greeks saw the poet Homer as the founder of geography. His works the Iliad and the Odyssey are works of literature, but both contain a great deal of geographical information. Homer describes a circular world ringed by a single massive ocean. The works show that the Greeks by the 8th century BC had considerable knowledge of the geography of the eastern Mediterranean. The poems contain a large number of place names and descriptions, but for many of these it is uncertain what real location, if any, is actually being referred to. Thales of Miletus is one of the first known philosophers known to have wondered about the shape of the world. He proposed that the world was based on water, and that all things grew out of it. He also laid down many of the astronomical and mathematical rules that would allow geography to be studied scientifically. His successor Anaximander is the first person known to have attempted to create a scale map of the known world and to have introduced the gnomon to Ancient Greece. Hecataeus of Miletus initiated a different form of geography, avoiding the mathematical calculations of Thales and Anaximander he learnt about the world by gathering previous works and speaking to the sailors who came through the busy port of Miletus. From these accounts he wrote a detailed prose account of what was known of the world. A similar work, and one that mostly survives today, is Herodotus' Histories. While primarily a work of history, the book contains a wealth of geographic descriptions covering much of the known world. Egypt, Scythia, Persia, and Asia Minor are all described, including a mention of India. The description of Africa as a whole are contentious, with Herodotus describing the land surrounded by a sea. Though, historically the Indian sea was thought of an inland sea which was that round of the southern part of Africa is surrounded by the eastern part of Asia by connecting land, which inference only after the circumnavigation of Africa by Vasco da Gama was abandoned by the western cartographers of the 15th century. Some, though, hold that the descriptions of areas such as India are mostly imaginary. Regardless, Herodotus made important observations about geography. He is the first to have noted the process by which large rivers, such as the Nile, build up deltas, and is also the first recorded as observing that winds tend to blow from colder regions to warmer ones. Pythagoras was perhaps the first to propose a spherical world, arguing that the sphere was the most perfect form. This idea was embraced by Plato and Aristotle presented empirical evidence to verify this. He noted that the Earth's shadow during an eclipse is curved, and also that stars increase in height as one moves north. Eudoxus of Cnidus used the idea of a sphere to explain how the sun created differing climatic zones based on latitude. This led the Greeks to believe in a division of the world into five regions. At each of the poles was an uncharitably cold region. While extrapolating from the heat of the Sahara it was deduced that the area around the equator was unbearably hot. Between these extreme regions both the northern and southern hemispheres had a temperate belt suitable for human habitation. These theories clashed with the evidence of explorers, however, Hanno the Navigator had traveled as far south as Sierra Leone, and it is possible other Phoenicians had circumnavigated Africa. In the 4th century BC the Greek explorer Pytheas traveled through northeast Europe, and circled the British Isles. He found that the region was considerably more habitable than theory expected, but his discoveries were largely dismissed by his contemporaries because of this. Conquerors also carried out exploration, for example, Caesar's invasions of Britain and Germany, expeditions/invasions sent by Augustus to Arabia Felix and Ethiopia (Res Gestae 26), and perhaps the greatest Ancient Greek explorer of all, Alexander the Great, who deliberately set out to learn more about the east through his military expeditions and so took a large number of geographers and writers with his army who recorded their observations as they moved east.
