Examine The World chart from the third century B.C.E. where Eratosthenes drew latitude and longitude lines through important places rather than spacing them at regular intervals as we do today. Briefly describe the misconceptions the Alexandrians had of the world.

Answer to Question 1

The Alexandrian perception of the world is reflected in the size of the continents and oceans on the chart. Continents comprise a large percentage of the world, whereas the ocean is only a small percentage. Today, we know that the ocean covers approximately 71 of Earth's surface. Alexandrians also placed themselves at the center of the world as evidenced by the longitude line that Eratosthenes drew through as one of the important places. It's difficult to consider Alexandria the center of the world when many continents (North America, South America, Africa, etc.) are missing.

Answer to Question 2
