=== Ancient Greece ===
Many scholars throughout history, such as Strabo, Kish, and Dilke, consider Homer to be the founder of the early Greek conception of Earth, and therefore of geography. Homer conceived Earth to be a disk surrounded by a constantly moving stream of Ocean, an idea which would be suggested by the appearance of the horizon as it is seen from a mountaintop or from a seacoast. This model was accepted by the early Greeks. Homer and his Greek contemporaries knew very little of the Earth beyond the Libyan desert of Egypt, the southwest coast of Asia Minor, and the northern boundary of the Greek homeland. Furthermore, the coast of the Black Sea was only known through myths and legends that circulated during his time. In his poems there is no mention of Europe and Asia as geographical concepts. That is why the big part of Homer's world that is portrayed on this interpretive map represents lands that border on the Aegean Sea. The Greeks believed that they occupied the central region of Earth and its edges were inhabited by savage, monstrous barbarians and strange animals and monsters: Homer's Odyssey mentions a great many of these.
Additional statements about ancient geography are found in Hesiod's poems, probably written during the 8th century BC. Through the lyrics of Works and Days and Theogony, he shows to his contemporaries some definite geographical knowledge. He introduces the names of such rivers as Nile, Ister (Danube), the shores of the Bosporus and the Euxine (Black Sea), the coast of Gaul, the island of Sicily, and a few other regions and rivers. His advanced geographical knowledge not only had predated Greek colonial expansions, but also was used in the earliest Greek world maps, produced by Greek mapmakers such as Anaximander and Hecataeus of Miletus, and Ptolemy using both observations by explorers and a mathematical approach.
Early steps in the development of intellectual thought in ancient Greece belonged to Ionians from their well-known city of Miletus in Asia Minor. Miletus was placed favourably to absorb aspects of Babylonian knowledge and to profit from the expanding commerce of the Mediterranean. The earliest ancient Greek who is said to have constructed a map of the world is Anaximander of Miletus (c. 611–546 BC), pupil of Thales. He believed that the Earth was a cylindrical form, a stone pillar suspended in space. The inhabited part of his world was circular, disk-shaped, and presumably located on the upper surface of the cylinder.
For constructing his world map, Anaximander is considered by many to be the first mapmaker. Little is known about the map, which has not survived. Hekatæus of Miletus (550–475 BC) produced another map fifty years later that he claimed was an improved version of the map of his illustrious predecessor.

Hecatæus's map describes the Earth as disk with an encircling Ocean, and with Greece placed in the center. This was a very popular contemporary Greek worldview, derived originally from the Homeric poems. Also, similar to many other early maps in antiquity, his map has no scale. As units of measurements, this map used "days of sailing" on the sea and "days of marching" on dry land. The purpose of this map was to accompany Hecatæus's geographical work that was called Periodos Ges, or Journey Round the World. Periodos Ges was divided into two books, "Europe" and "Asia", with the latter including Libya, the name of which was an ancient term for all of known Africa.
The work divides the world into two continents, Asia and Europe. Hecatæus depicts the line between the Pillars of Hercules through the Bosporus, and the Don River as a boundary between the two. He was the first writer known to have thought that the Caspian flows into the encircling ocean—an idea that persisted long into the Hellenic period. He was particularly instructive about the Black Sea, adding many geographic places that already were known to Greeks through the colonization process. To the north of the Danube, according to Hecatæus, were the Rhipæan (gusty) Mountains, beyond which lived the Hyperboreans—peoples of the far north. Hecatæus depicted the origin of the Nile River at the southern encircling ocean. This assumption helped Hecatæus propose a solution to the mystery of the annual flooding of the Nile. He believed that the waves of the ocean were a primary cause of this occurrence. A map based on Hecataeus's was intended to aid political decision-making. According to Herodotus, that map was engraved into a bronze tablet and was carried to Sparta by Aristagoras during the revolt of the Ionian cities against Persian rule from 499 to 494 BC.
Anaximenes of Miletus (6th century BC), who studied under Anaximander, rejected the views of his teacher regarding the shape of the Earth and instead, he visualized the Earth as a rectangular form supported by compressed air.
Pythagoras of Samos (c. 560–480 BC) speculated about the notion of a spherical Earth with a central fire at its core. He is sometimes incorrectly credited with the introduction of a model that divides a spherical Earth into five zones: one hot, two temperate, and two cold—northern and southern. This idea, known as the zonal theory of climate, is more likely to have originated at the time of Aristotle.
Scylax, a sailor, made a record of his Mediterranean voyages in c. 515 BC. This is the earliest known set of Greek periploi, or sailing instructions, which became the basis for many future mapmakers, especially in the medieval period.
The way in which the geographical knowledge of the Greeks advanced from the previous assumptions of the Earth's shape was through Herodotus and his conceptual view of the world. This map also did not survive and many have speculated that it was never produced. A possible reconstruction of his map is displayed adjacent.
