The World according to Eratosthenes, 220 BC

A facsimile of the world map by Eratosthenes (around 220 BC). Eratosthenes is the ancient Greek mathematician and geographer attributed with devising the first system of Latitude and Longitude. He was also the first know person to calculate the circumference of the earth. This is a facsimile of the map he produced based on his calculations. The map shows the routes of exploration by Nearchus from the mouth of the Indus River (325 BC, after the expedition to India by Alexander the Great), and Pytheas (300 BC) to Britannia. Place names include Hellas (Greece), Pontus Euxinus (Black Sea), Mare Caspium (Caspian Sea), Gades (Cadiz), Columnæ Herculis (Gibraltar), Taprobane (Sri Lanka), Iberes (Iberian peninsula), Ierne (Ireland), and Brettania (Britain), the rivers Ister (Danube), Oxus (Amu Darya), Ganges, and Nilus (Nile), and mountain systems. The map shows his birthplace in Libya (Cyrene), the Egyptian cities of Alexandria and Syene (Aswan) where Eratosthenes made his calculations of the earth's circumference, and the latitudes and longitudes of several locations based on his measurements in stadia. Place Names: A Complete Map of Globes and Multi-continent, Europa, Libya, Asia, India, Scythia, Arabi. Source: http://etc.usf.edu/maps/pages/10400/10489/10489.htm
