Alvise Cadamosto

Alvise Cadamosto was a Venetian explorer and slave trader, who was hired by the Portuguese prince Henry the Navigator and undertook two known journeys to West Africa in 1455 and 1456, accompanied by the Genoese captain Antoniotto Usodimare. Some have credited Cadamosto and his companions with the discovery of the Cape Verde Islands and the points along the Guinea coast from the Gambia River to the Geba River, the greatest leap in the Henrican discoveries since 1446. Cadamosto's accounts of his journeys, including his detailed observations of West African societies, have proven invaluable to historians.
