Name by which the Italian painter Pietro Buonaccorsi ( Florence 1501 - Rome 1547) is known. Already a pupil of Ridolfo Ghirlandaio, he then assisted a painter called “il Vaga”, and took this nickname from him. Having gone to Rome , he mostly looked at Michelangelo and Raffaello, drawing from this last one the taste for rhythmic cadences, sometimes interpreted by him in a somewhat affected manner. He worked in Rome: frescoes in the Logge Vaticane and in the Royal Hall of the Vatican (iter 9); in Castel Sant'Angelo ( iter 9 ); in the church of S. Marcello al Corso ( iter 7 ) and in Genoa (frescoes in Palazzo Doria). His best-known painting is the Nativity ( Richmond ). His tomb is in the Pantheon ( iter 6 ).
