The geographical location is supported by textual references to the island of Diomedes (now Isole Tremiti), in Puglia, the binding from an earlier southern Italian manuscript, and the watermark similar to one used in Naples later, but some tables in the text give astronomical information for the 45th latitude, which passes through northern Italy. Dates in the text are 1501 (f. 16v, 19v) and 1502 (f. 6r)., Lawrence J. Schoenberg & Barbara Brizdle Manuscript Initiative., Latin.
