1911 Encyclopædia Britannica/Vivaldo, Ugolino and Sorleone de

VIVALDO, UGOLINO and SORLEONE DE (fl. 1291–1315), Genoese explorers, connected with the first known expedition in search of an ocean way from Europe to India. Ugolino, with his brother Guido or Vadino Vivaldo, was in command of this expedition of two galleys, which he had organized in conjunction with Tedisio Doria, and which left Genoa in May 1291 with the purpose of going to India "by the Ocean Sea" and bringing back useful things for trade. Planned primarily for commerce, the enterprise also aimed at proselytism. Two Franciscan friars accompanied Ugolino. The galleys were well armed and sailed down the Morocco coast to a place called Gozora (Cape Nun), in 28° 47' N., after which nothing more was heard of them. Early in the next (14th) century, Sorleone de Vivaldo, son of Ugolino, undertook a series of distant wanderings in search of his father, and even penetrated, it is said, to Magidoxo on the Somali coast. In 1455 another Genoese seaman, Antoniotto Uso di Mare, sailing with Cadamosto in the service of Prince Henry the Navigator of Portugal, claimed to have met, near the mouth of the Gambia, with the last descendant of the survivors of the Vivaldo expedition. The two galleys, he was told, had sailed to the Sea of Guinea; in that sea one was stranded, but the other passed on to a place on the coast of Ethiopia-Mena or Amenuan, near the Gihon (here probably meaning the Senegal) — where the Genoese were seized and held in closing captivity.
