 When Cosimo was exiled from Florence, Donatello went to Rome, remaining until 1433.The two works that testify to his presence in this city, the "Tomb of Giovanni Crivelli" at Santa Maria "in Aracoeli", and the "Ciborium" at St. Peter's Basilica, bear a strong stamp of classical influence.Donatello's return to Florence almost coincided with Cosimo's.
