[1291.] Doria and Vivaldi, Genoese, undertook a voyage down the African coast with a view of reaching India, and were last heard of at a place called Gozora. On this voyage, which rests on several authorities, has been founded a claim that the Italians preceded the Portuguese in passing Cape Bojador. Major, _Prince Henry_, pp. 99-110, concludes from an examination of all the documents that there are no grounds for this claim, although admitting the voyage and its purpose, in fact everything but its success. Gozora was probably Cape Non. Kohl regards this expedition as uncertain. One of the documents gives the date as 1281; from which circumstance Kohl and Humboldt erroneously make of it two voyages. D'Avesac, in _Nouvelles Annales des Voyages_, 1845, tom. cviii. p. 45, has the date 1285. Muñoz, _Hist. Nuevo Mundo_, pp. 30-1, speaks of Genoese expeditions and the rediscovery of the Canaries during this century. [1306.] On a map made by the Venetian Sanuto in 1306, Africa is represented as surrounded by the sea, but there is no evidence that the geography of that region is derived from any actual observations. The map simply shows one of the two theories then held respecting the shape of southern Africa. [1332 et seq.] Sir John Mandeville, an English physician, between 1332 and 1366, travelled in eastern parts, including the Holy Land, India, and China. On his return he wrote in three languages an account of his adventures, with descriptions of the countries visited. See _Hakluyt Soc._, _Divers Voy._, Introd. p. xliii. His work corroborates that of Marco Polo, and although full of exaggerations, and probably tampered with by copyists in respect to adventures and anecdotes, "yet," says Irving, "his accounts of the countries which he visited have been found far more veracious than had been imagined." _Purchas_, _His Pilgrimes_, vol. iii. pp. 128-38; _Travels of Sir John Mandeville_, London, 1725.
