The expedition[131] (1402-12) of the Sieur de Béthencourt, Lord of Granville la Teinturière, of the Pays de Caux in Normandy, was chiefly concerned with the Canaries[132]--like the voyages of the Spaniards Francisco Lopez (1382), and Alvaro Becarra (? 1390, etc.) But, after achieving fair success in the islands, De Béthencourt attempted (apparently in 1404) an exploration of the mainland coast "from Cape Cantin, half way between the Canaries and Spain," to Cape "Bugeder" or Bojador,[133] the famous promontory to the right or east of the Canaries. But this was left unfinished; and De Béthencourt's chaplains, in describing their Seigneur's intentions beyond the "Bulging Cape," can only fall back on a certain Book of a Spanish Friar,[134] which professed to give a description of Guinea, and the River of Gold. This last was said by the Friar to be 150 leagues from "the Cape Bugeder," and the French priests declare that "if things were such as described," their lord hoped sometime to reach the said river, "whereby access would be gained to the land of Prester John, whence come so many riches."

This was lost sight of till 1870, when it was found by Marcos Jimenez de la Espada, who published it in the _Boletin de la Sociedad Geographica de Madrid_ 1877. "It is certainly not a record of actual travel, but probably the description of an imaginary journey, compiled with the help of a richly illustrated typical portolano, reports by far-famed and travelled men, and such geographical works as were accessible to the author. Many names here occurring are, however, not to be found on the portolanos of the fourteenth century.... Every city or country spoken of in the book has a chapter to itself, followed by a representation of the flag or arms of the State. These also seem ... taken from some portolano." See the _Conquest of the Canaries_ (Hakluyt Soc. ed., ch. 55). The _Conosçimiento_ cannot well be of later date than 1330-1340. In many places it copies Edrisi.]
