Pietro most likely began studying painting in local workshops in Perugia such as those of Bartolomeo Caporali or Fiorenzo di Lorenzo. The date of the first Florentine sojourn is unknown; some make it as early as 1466/1470, others push the date to 1479. According to Vasari, he was apprenticed to the workshop of Andrea del Verrocchio alongside Leonardo da Vinci, Domenico Ghirlandaio, Lorenzo di Credi, Filippino Lippi and others. Piero della Francesca is thought to have taught him perspective form. In 1472, he must have completed his apprenticeship since he was enrolled as a master in the Confraternity of St Luke. Pietro, although very talented, was not extremely enthusiastic about his work.
