Nuno Tristão

Nuno Tristão was a 15th-century Portuguese explorer and slave trader, active in the early 1440s, traditionally thought to be the first European to reach the region of Guinea (legendarily, as far as Guinea-Bissau, but more recent historians believe he did not go beyond the Gambia River).

Nuno Tristão was a knight of the household of Henry the Navigator. In 1441, Tristão was dispatched by Henry in one of the first prototypes of the lateen-rigged caravel to explore the West African coast beyond Cape Barbas, the furthest point reached by Henry's last captain five years earlier (Afonso Gonçalves Baldaia, in 1436). Around Rio de Oro, Tristão met up with the ship of Antão Gonçalves, who had been sent on a separate mission by Henry that same year to hunt monk seals that basked on those shores. But Gonçalves happened to capture a solitary young camel-driver, the first native encountered by the Portuguese since the expeditions began in the 1420s. Nuno Tristão, who carried on board one of Henry's Moorish servants to act as an interpreter, interrogated Gonçalves's captive camel-driver. Tristão and Gonçalves were led by his information to a small Sanhaja Berber fishing camp nearby. The Portuguese attacked the fishermen, taking some ten captives, the first African slaves taken by the Portuguese back to Europe. Gonçalves returned to Portugal immediately after the slave raid, but Nuno Tristão continued south, reaching as far as Cape Blanc (Cabo Branco), before turning back.
