It’s as easy as A, B, Sea: D for Diaz, Bartholomeu

Bartholomeu Diaz was a Portuguese navigator who was the first person to sail around the Cape of Good Hope. His flotilla of three ships are thought to have rounded the tip of Africa the first week of February in 1488. He was sent by Prince John (eventually King) to explore the west coast of Africa south of fifteen degrees latitude in an effort to understand how Africa and India are linked.
