It only needs a perusal of such a collection of letters, reports, and narratives as is to be found in _Alguns documentos do Archivo nacional_ (Lisbon, 1892) to convince us that there were men holding high positions in those days whose literary abilities fell short of those which can be claimed on behalf of our author. Moreover, it is not likely that access to the information required to enable him to write a _Roteiro da Viagem_ would have been given to a “common sailor or soldier”, even if such a person had been bold enough to ask for it. We shall now follow Prof. Kopke in his “process of elimination”:— 1. The author, in the course of his narrative, mentions a number of persons by name, and these we must eliminate forthwith. They are: Vasco and Paulo da Gama, Nicolau Coelho (p. 22), Pero d’Alenquer (p. 5), João de Coimbra (p. 30), Martin Affonso (pp. 12, 17), Sancho Mexia (p. 6), and Fernão Veloso (p. 7). 2. We know further that the author served on board the _S. Raphael_.[17] This disposes of Gonçalo Alvares and Diogo Dias[18] of the _S. Gabriel_; and of Gonçalo Nunes, Pero Escolar, and Alvaro de Braga, of the _Berrio_. 3. The author mentions certain things as having been done by persons whose names he does not give. The name of one of these is supplied by Castanheda and Barros. We thus learn from Barros that Fernão Martins “was the sailor mentioned by the author (p. 23) as being able to speak the language of the Moors; and from Castanheda (I, p. 51) that he was one of the two men sent with a message to the King of Calecut (p. 50). The convict who was sent to Calecut on May 21st (p. 48) was João Nunez, according to Correa. The author states (p. 64, line 18, and p. 65, last line) that the captain-major sent three men along the beach in search of the ships’ boats. According to Castanheda (I, pp. 71 and 72), one of these men was Gonçalo Pires. We may therefore strike out all these names from the list of possible authors. 4. Three members of the expedition are reported to have died during the voyage, namely, Pedro de Covilhão, the priest; Pedro de Faria de Figueredo, and his brother Francisco, all of them mentioned by Faria y Sousa alone. 5. Lastly, there are four convicts whose names are given by Correa, none of whom is likely to have been the author of the MS. The presence of some of these convicts is, moreover, very doubtful. We have thus accounted for all the members of the expedition whose names are known, with the exception of eight.
