Antonio Pigafetta also wrote a book, in which a detailed account of the voyage was given. It is quite unclear when it was first published and what language had been used in the first edition. The remaining sources of his voyage were extensively studied by Italian archivist Andrea da Mosto, who wrote a critical study of Pigafetta's book in 1898 ("Il primo viaggio intorno al globo di Antonio Pigafetta e le sue regole sull'arte del navigare") and whose conclusions were later confirmed by J. Dénucé.
