Herodotus traveled extensively, collecting information and documenting his findings in his books on Europe, Asia, and Libya. He also combined his knowledge with what he learned from the people he met. Herodotus wrote his Histories in the mid-5th century BC. Although his work was dedicated to the story of long struggle of the Greeks with the Persian Empire, Herodotus also included everything he knew about the geography, history, and peoples of the world. Thus, his work provides a detailed picture of the known world of the 5th century BC.
Herodotus rejected the prevailing view of most 5th-century BC maps that the Earth is a disk surrounded by ocean. In his work he describes the Earth as an irregular shape with oceans surrounding only Asia and Africa. He introduces names such as the Atlantic Sea, and the Erythrean Sea, which translates as the "Red Sea". He also divided the world into three continents: Europe, Asia, and Africa. He depicted the boundary of Europe as the line from the Pillars of Hercules through the Bosphorus and the area between the Caspian Sea and the Indus River. He regarded the Nile as the boundary between Asia and Africa. He speculated that the extent of Europe was much greater than was assumed at the time and left Europe's shape to be determined by future research.
In the case of Africa, he believed that, except for the small stretch of land in the vicinity of Suez, the continent was in fact surrounded by water. However, he definitely disagreed with his predecessors and contemporaries about its presumed circular shape. He based his theory on the story of Pharaoh Necho II, the ruler of Egypt between 609 and 594 BC, who had sent Phoenicians to circumnavigate Africa. Apparently, it took them three years, but they certainly did prove his idea. He speculated that the Nile River started as far west as the Ister River (Danube) in Europe and cut Africa through the middle. He was the first writer to assume that the Caspian Sea was separated from other seas and he recognised northern Scythia as one of the coldest inhabited lands in the world.
Similar to his predecessors, Herodotus also made mistakes. He accepted a clear distinction between the civilized Greeks in the center of the Earth and the barbarians on the world's edges. In his Histories it is clear that he believed that the world became stranger and stranger when one traveled away from Greece, until one reached the ends of the Earth, where humans behaved as savages.
While various previous Greek philosophers presumed the Earth to be spherical, Aristotle (384–322 BC) is credited with proving the Earth's sphericity. His arguments may be summarized as follows:

The lunar eclipse is always circular
Ships seem to sink as they move away from view and pass the horizon
Some stars can be seen only from certain parts of the Earth.

A vital contribution to mapping the reality of the world came with a scientific estimate of the circumference of the earth. This event has been described as the first scientific attempt to give geographical studies a mathematical basis. The man credited for this achievement was Eratosthenes (275–195 BC), a Greek scholar who lived in Hellenistic North Africa. As described by George Sarton, historian of science, "there was among them [Eratosthenes's contemporaries] a man of genius but as he was working in a new field they were too stupid to recognize him". His work, including On the Measurement of the Earth and Geographica, has only survived in the writings of later philosophers such as Cleomedes and Strabo. He was a devoted geographer who set out to reform and perfect the map of the world. Eratosthenes argued that accurate mapping, even if in two dimensions only, depends upon the establishment of accurate linear measurements. He was the first to calculate the Earth's circumference (within 0.5 percent accuracy). His great achievement in the field of cartography was the use of a new technique of charting with meridians, his imaginary north–south lines, and parallels, his imaginary west–east lines. These axis lines were placed over the map of the Earth with their origin in the city of Rhodes and divided the world into sectors. Then, Eratosthenes used these earth partitions to reference places on the map. He also divided Earth into five climatic regions, which was proposed at least as early as the late sixth or early fifth century BC by Parmenides: a torrid zone across the middle, two frigid zones at extreme north and south, and two temperate bands in between. He was likely also the first person to use the word "geography".

==== Pomponius Mela ====

Pomponius Mela (1st century B.C.) is unique among ancient geographers in that, after dividing the earth into five zones, of which two only were habitable, he asserts the existence of antichthones inhabiting the southern temperate zone, inaccessible to the folk of the northern temperate regions due to the unbearable heat of the intervening torrid belt. On the divisions and boundaries of Europe, Asia and Africa, he repeats Eratosthenes; like all classical geographers from Alexander the Great (except Ptolemy) he regards the Caspian Sea as an inlet of the Northern Ocean, corresponding to the Persian Gulf and the Red Sea on the south.
