 However, if Vasari's date is correct, then the pope must have been Eugene IV and not Nicholas, who was elected Pope only on 6 March 1447.Moreover, the archbishop in 1446–1459 was the Dominican Antoninus of Florence (Antonio Pierozzi), canonized by Pope Adrian VI in 1523.In 1447 Fra Angelico was in Orvieto with his pupil, Benozzo Gozzoli, executing works for the Cathedral.
