Bartolomeu Dias, Portuguese explorer and navigator (b. 1451)
Bartolomeu Dias (c. 1450 – 29 May 1500) was a Portuguese mariner and explorer. In 1488, he became the first European navigator to round the southern tip of Africa and to demonstrate that the most effective southward route for ships lay in the open ocean, well to the west of the African coast. His discoveries effectively established the sea route between Europe and Asia.
