Great Explorers of the World : Marco Polo, Ibn Battuta, Vasco Da Gama, Christopher Columbus, Ferdinand Magellan, Captain Cook, Lewis and Clark, Livingstone and Stanley, the Apollo Mission to the Moon

Here are the stories of nine great adventures and the lives of the men who took part in them.

Their journeys are placed within their historical context, but also contain the words of the men themselves.
