| This map shows the world as Greek geographer and astronomer Ptolemy envisioned it in the 2nd century ad. Ptolemy’s map, based on the accounts of sailors, traders, and armies who had traveled in Europe, Africa, and Asia, shows the Indian Ocean as an enclosed body of water. This misconception persisted in Europe until 1488, when Bartolomeu Dias rounded the Cape of Good Hope in southern Africa and sailed from the Atlantic Ocean to the Indian Ocean. |
