[157] Ships from Portugal (according to Sántarem, Cosmographie, i, 275, copied by Oliveira Martins, Filhos de D. João, i, 68), visited the Canaries under Affonso IV, between 1331 and 1344. Perhaps this is only a loose reference to the expedition of 1341.
[158] Clement VI. Major, Prince Henry, 140, and Conquest of Canaries (Hakluyt Soc.), xi, has apparently confused matters, giving the date of 1334 (in the Pontificate of Benedict XII), and implying a grant by Clement VI.
[159] The account that has come down to us is by Boccaccio(?) (discovered in 1827 by Sebastiano Ciampi, who identified the handwriting), and was professedly compiled from letters written to Florence by certain Florentine merchants residing in Seville. Among these, "Angelino del Tegghia dei Corbizzi, a cousin of the sons of Gherardino Gianni," is especially mentioned.
[160] Major conjectures Fuerteventura.
[161] Grand Canary?
[162] Major here suggests the pines of Ferro.
[163] Gomera?
[164] Probably Teneriffe. Palma has also been suggested, with less likelihood.

[166] Ayala, Chronicle of Henry III of Castille, asserts that in 1393, mariners of Biscay, Guipuzcoa, and Seville, visited the Canaries, and brought back spoils. Teneriffe they called the Isle of Hell (Inferno), from its volcano. They also landed on other islands of the group which they called Lencastre, Graciosa, Forteventura, Palma, and Ferro.
