to Rome, and was made his partner, receiving a third of the profits. He may have done some of the Zipporah subject. The Sistine frescoes were the major high Renaissance commission in Rome. The altar wall was also painted with the Assumption, the Nativity, and Moses in the Bulrushes. These works were later destroyed to make a space for Michelangelo's Last Judgement. Between 1486 and 1499, Perugino worked mostly in Florence, making one journey to Rome and several to Perugia, where he may have maintained a second studio. He had an established studio in Florence, and received a great number of commissions. His Pietà (1483–1493) in the Uffizi is an uncharacteristically stark work that avoids Perugino's sometimes too easy sentimental piety. According to Vasari, Perugino was to return to Florence in September 1493 to marry Chiara, daughter of architect Luca Fancelli. The same year, Perugino made Florence his permanent home once again, though he continued to accept some work elsewhere. Later career In 1499, the guild of the cambio (money-changers or bankers) of Perugia asked him to decorate their audience-hall, the Sala delle Udienze del Collegio del Cambio. The humanist Francesco Maturanzio acted as his consultant. This extensive scheme, which may have been finished by 1500, comprised the painting of the vault, showing the seven planets and the signs of the zodiac (Perugino being responsible for the designs and his pupils most probably for the execution), and the representation on the walls of two sacred subjects: the Nativity and Transfiguration; in addition, the Eternal Father, the cardinal virtues of Justice, Prudence, Temperance, Fortitude, Cato as the emblem of wisdom, and numerous life-sized figures of classic worthies, prophets, and sibyls figured in the program. On the mid-pilaster of the hall Perugino placed his own portrait in bust-form. It is probable that Raphael, who in boyhood, toward 1496, had been placed by his uncles under the tuition of Perugino, bore a hand in the work of the vaulting. Perugino was made one of the priors of Perugia in 1501. On one occasion Michelangelo told Perugino to his face that he was a bungler in art (goffo nell arte): Vannucci brought an action for defamation of character, unsuccessfully. Put on his mettle by this mortifying transaction, he produced the masterpiece of the Madonna and Saints for the Certosa of Pavia, now disassembled and scattered among museums: the only portion in the Certosa is
