The personality of Ambrogio Bon, perhaps Johann Carl Loth’s closest collaborator, raised the interest of various scholars in recent years, who tried to focus his profile in relation to that of his more famous master, but the scarcity of documents and works has so far confined him in the role of a minor artist, not yet well defined. The present contribution reveals the date of his death, hitherto unknown, and adds a new work to his catalogue, an interesting altarpiece depicting "San Filippo Neri kneeling in front of the Virgin and Child", kept in the Venetian church of San Giuseppe di Castello, which can be put alongside the few certain works of the painter.
