After his father Hieronimo’s death in 1570, Marino Grimani, who was to become doge in April 1595, fell responsible for the completion of the magnificent family palace built on the Canale Grande after a project by Michele Sanmicheli. In 1578 Marino ordered a series of paintings by some of the major painters in Venice to adorn his apartment on the first floor of the palace. The payments for these works are still in the family archive, now preserved in the Archivio di Stato of Venice, and were published by this author some twenty years ago. Palma il Giovane figures among the artists involved, and this was his first documented commission, a frieze composed of family portraits and allegories in one of the principal rooms. New research has uncovered the major part of these portraits, which prove very useful in understanding the painter’s style in the first years of his career. They also bear witness to the political and cultural ambitions of the patron who ordered them.
