Documenti inediti su Luca Pacioli, Piero della Francesca e Leonardo da Vinci, con alcuni autografi

The work brings together numerous previously unpublished documents on Luca Pacioli, Leonardo da Vinci, Piero della Francesca and their families. The documents are first explained and commented on in detail, and then transcribed in the respective Appendices. The first, and more substantial, part contains information on Pacioli, the periods he spent in the town of his birth, Sanse-polcro, and his relations with Piero and Leonardo; the second, along with documents concerning Leonardo directly, chiefly provides unpublished information on his relatives, updating one of our earlier publications on the Da Vinci family. The documents include three autographs by Luca Pacioli and one by Piero della Francesca.
