Osorio[443] likewise gives an account of a mutiny, but says that it occurred before the Cape was doubled. He differs in other respects from Correa, stating, for instance, that “_all_ the pilots were put in chains.” As Osorio’s book was published in 1571, whilst Correa’s MS., although written in 1561, only reached Lisbon in 1583, it is not probable that the former borrowed from the latter. They may both have derived their information from the same impure source, and accepted an idle tradition as the record of a fact. That there may have been some discontent among the men is quite possible, but we cannot believe that the pilots intended to head a mutiny. We quite agree with Professor Kopke,[444] when he prefers the authority of Barros, Goes, and Castanheda, and of the author of this “Journal”, to that of Osorio. This applies with still greater force to the absurdly elaborate account of Correa. Professor A. Herculano, in the second edition of the _Roteiro_ (p. viii), discredits Professor Kopke’s notes on the insufficient ground that the eminent authorities referred to above refrained from every allusion to a mutiny from a “fear of tarnishing the fame of Vasco da Gama’s companions.” But Herculano believed in Correa—we do not. Early on December 15th, Vasco once more made for the land, and found himself abreast, the Ilhéos Chãos (Bird islands) in Algoa Bay, having thus covered only a couple of hundred miles in the course of seven days. Fair progress was made for a couple of days after this. The vessels kept near the coast, and being favoured by the wind, and also by an inshore counter-current, were able to pass beyond the pillar set up by Dias and the furthest point reached by that navigator. But on December 17th the wind sprang round to the east. Vasco da Gama stood out to sea, and was thus made to experience the full force of the Agulhas current, which here runs at a distance of about ten miles from the land. He was unable to make head against the combined forces of wind and current, and when, on December 20th, he again approached the land he found himself at the Ilhéo da Cruz, 27 miles to the westward of the group of islets from which he had started on the 15th (see p. 15). Henceforth, for a number of days, the wind proved propitious, and by December 25th our voyagers, clinging all the while to the coast, had proceeded 240 miles beyond the furthest point reached by Dias (as estimated by the pilots); and three days afterwards they cast anchor and took a quantity of fish. This locality we identify with Durnford Point—the Ponta da Pescaria of the old charts—300 miles beyond the Rio de Infante (which was Dias’s furthest), and 370 miles beyond the Ilhéo da Cruz. The daily run since December 20th had thus averaged 46 miles.
