A Portuguese navigator, sent on a voyage of discovery by John II., in the command of two ships; sailed down the W. coast of Africa and doubled the Cape of Good Hope, which, from the storm that drove him past it, he called the Cape of Storms; returning to Lisbon he was superseded by Vasco da Gama, or rather subordinated to him; subsequently accompanied Cabral on his voyage to Brazil, and was lost in a storm in 1500.
