Portuguese navigator, he was sent twice (1482 and 1484) to the Discoveries by D. João II.
He set off to Mina, and from there he went to Zaire. After a series of vicissitudes, he reached "ponta dos Farilhões" (sierra Parda), at 22° 10', South latitude, and then returned to Zaire, which he climbed, to visit the king of Congo.
He returned to Tagus river in 1486, bringing with him the necessary knowledge to reach South Africa by sailing at large, like Vasco da Gama did.
