on a galley with the explicit objective of finding the "River of Gold" (Riu de l'Or), where he heard that most people along its shores were engaged in the collection of gold and that the river was wide and deep enough for the largest ships. Nothing more is heard of him either. In 1402, after establishing the first European colony on the Canary Islands, the French Norman adventurers Jean de Béthencourt and Gadifer de la Salle set about immediately probing the African coast, looking for directions to the mouth of Senegal. The project of finding the Senegal was taken up in the 1420s by the Portuguese Prince Henry the Navigator, who invested heavily to reach it. In 1434, one of Henry's captains, Gil Eanes, finally surpassed Cape Bojador and returned to tell about it. Henry immediately dispatched a follow up mission in 1435, under Gil Eanes and Afonso Gonçalves Baldaia. Going down the coast, they turned around the al-Dakhla peninsula in the Western Sahara and emerged into an inlet, which they excitedly believed to be the mouth of the Senegal River. The name they mistakenly bestowed upon the inlet - "Rio do Ouro" - is a name it would remain stuck with down to the 20th century. Realizing the mistake, Henry kept pressing his captains further down the coast, and in 1445, the Portuguese captain Nuno Tristão finally reached the Langue de Barbarie, where he noticed the desert end and the treeline begin, and the population change from 'tawny' Sanhaja Berbers to 'black' Wolof people. Bad weather or lack of supplies prevented Tristão from actually reaching the mouth of the Senegal River, but he rushed back to Portugal to report he had finally found the "Land of the Blacks" (Terra dos Negros), and that the "Nile" was surely nearby. Shortly after (possibly still within that same year) another captain, Dinis Dias (sometimes given as Dinis Fernandes) was the first known European since antiquity to finally reach the mouth of the Senegal River. However, Dias did not sail upriver, but instead kept sailing down the Grande Côte to the bay of Dakar. The very next year, in 1446, the Portuguese slave-raiding fleet of Lançarote de Freitas arrived at the mouth of the Senegal. One of its captains, Estêvão Afonso, volunteered to take a launch to explore upriver for settlements, thus becoming the first European to actually enter the Senegal river. He
