Discoverers and Explorers - Edward R Shaw - Bog

Discoverers and Explorers is a classic history text that describes the exploits of several famous world explorers. Four hundred years ago most of the people who lived in Europe thought that the earth was flat. They knew only the land that was near them. They knew the continent of Europe, a small part of Asia, and a strip along the northern shore of Africa. They thought this known land was surrounded by a vast body of water that was like a broad river. Sailors were afraid to venture far upon this water, for they feared they would fall over the edge of the earth.
