And he listed the coordinates for 8,000 locations in Eurasia and northern Africa based on parallels of latitude and meridians of longitude, a precursor to today’s system. Ptolemy explained map projections-depicting a globe on a flat plane.
Completed around 150 A.D., Geographia served as a how-to manual for cartography. And by 200 B.C., the scholar Eratosthenes compared the angles of shadows cast simultaneously in two distant cities to accurately estimate the planet’s circumference within 1,000 miles.Ĭombining the work of earlier Greek scholars with travelers’ stories and town records from across the then-Roman world, Greek-Egyptian astronomer Ptolemy compiled Geographia, an eight-volume atlas that formed the basis for the next 1,500 years of mapmaking. The philosopher Pythagorus theorized as early as the 6th century B.C. The Greeks were the first known culture to apply a scientific approach to measuring and mapping the world.

Other early maps served more practical needs, such as the stick and shell charts built to denote currents around islands in the South Pacific over 2,000 years ago, or the Egyptian papyrus maps that led miners through the desert in the 12th century B.C. Though its geography is limited, this map reveals the inherent bias of mapmakers to place themselves at the literal center of the world. Babylon, likely the world’s most populous city at the time, is surrounded by neighboring cities represented by small circles, all within a greater circle to denote the ocean. The 5-inch stone tablet is centered around Babylon, the wide rectangle, which straddles the Euphrates River, depicted by the crooked lines running from top to bottom.
