This circular room was decorated between 1532 and 1533 by the painter Marcello Fogolino from Vicenza, creating here his probable masterpiece. The centre of the vault is taken up by Bernardo Cles’s imposing cardinal coat of arms. The magnificent stucco decoration is set with four ovals depicting the episodes of Julius Caesar’s life: Ptolemy presenting the head of Pompey, the Triumvirate, Caesar and the Senate and a wonderfully suggestive nocturnal Triumph. Fourteen Roman emperors on horseback in evocative landscapes are depicted in the lunettes. In the small ovals between the lunettes are charmingly made male and female figures, while in the gables are satyrs and fanciful animals.
