The author reports the full text of a previously unpublished manuscript
by Michele Caffi – kept at the Archivio della Società Storica Lombarda in
Milan – which allows to clarify the tormented events of the now dismembered marble complex of the tomb of St. Evasius in the Cathedral of Casale Monferrato. The manuscript accounts for some excerpts from a now missing convention signed in Milan on January 5th 1548, in which Bambaia and Cristoforo Lombardi – appointed to the building of the tomb in 1525, together with Gian Giacomo Della Porta – entrust
stonemason Giovanni Antonio Della Torre from Como with the realization of some parts of the monument, as well as the assemblage of the works in Casale, which probably never started. The contract also constitutes the very last known document of the activity of Bambaia, who would die six months later.
