Ptolemy's world map. Copy of an original map which was constructed by the Greek astronomer Ptolemy around 150 AD. Medieval scholars in 1482 used Ptolemy's instructions in his book Geography to construct copies of his map, which shows parts of the three continents (Europe, Asia and Africa) that surround the Mediterranean Sea (upper left). Earlier medieval maps had relied on an inaccurate and mythological geography but this map showed only the known world and used projection techniques to produce a highly accurate model, particularly of the Mediterranean.
