Four of these—João de Sá, Alvaro Velho, João Palha and João de Setubal—are stated to have been among the thirteen who attended Vasco da Gama to Calecut (p. 51), and of these, João de Sá was clerk in the _S. Raphael_, the author’s ship. He certainly might have been the author. Prof. Kopke thinks not, first, because of the author’s supposed humble position; secondly, because João de Sá, if we may credit an anecdote recorded by Castanheda (I, p. 57),[19] had his doubts about the people of India being Christians, whilst the author unhesitatingly affirms them to be so. The only other person mentioned by Castanheda as having been connected with the expedition is Alvaro Velho, a soldier, who, according to Prof. Kopke, may “fairly be looked upon as the author of this Journal.” He admits, however, that this conclusion is acceptable only on the assumption that Castanheda knew the author: a purely gratuitous assumption, in our opinion. Castanheda only mentions six out of the thirteen who were present at Vasco da Gama’s audience of the Zamorin. Correa mentions two others—João de Setubal and João Palha. Five remain thus to be accounted for; and, although these may have included servants and trumpeters, not likely to have troubled about keeping a journal, our author may have been among them. It will thus be seen that this process of elimination has led to no result, and that we cannot even tell whether the author’s name occurs in any single account of this expedition. Comparing his “Journal” with the contents of Sernigi’s first letter, it almost seems as if he had been the person from whom the Florentine derived the bulk of his information. In that case his name may perhaps turn up some day in the Italian archives. If our choice were limited to Alvaro Velho and João de Sá, we should feel inclined to decide in favour of the latter. Correa mentions three other persons as having been with Vasco da Gama: namely, João Figueiro, whose diary he claims to have used, and who cannot therefore have been the author of a “Journal” the contents of which are so widely different; André Gonçalves and João d’Amoxeira. Camões adds a fourth name, that of Leonardo Ribeyra. This exhausts the muster-roll, as far as the names are known to us. _The Portuguese Editions of the “Roteiro”._[20]
