At the end of his book, Pigafetta stated that he had given a copy to Charles V. Pigafetta's close friend, Francesco Chiericati, also stated that he had received a copy and it is thought that the regent of France may have received a copy of the latter. It has been argued that the copy Pigafetta had provided may have been merely a short version or a draft. It was in response to a request, in January 1523, of the Marquis of Mantua that Pigafetta wrote his detailed account of the voyage.
