De vita beati Laurentii Justiniani Patriarchae Venetiarum, ad Monachos Carthusienses

First edition of this life of Lorenzo Giustinian by his nephew Bernardo Giustinian. Lorenzo was the first patriarch of Venice and a Roman Catholic saint. It is a quintessential Venetian text and probably published as part of a campaign to have Lorenzo canonised (which didn’t occur in fact until 1690). From a bibliophile point of view, it is interesting as it is one of the very few copies printed on vellum – you can also see manuscript corrections from the time which would have been made either by the printer’s corrector, or possibly the author, as they only appear in the vellum copies.
