The putto disappeared during the Middle Ages and was revived during the Quattrocento. The revival of the figure of the putto is generally attributed to Donatello, in Florence in the 1420s, although there are some earlier manifestations (for example the tomb of Ilaria del Carretto, sculpted by Jacopo della Quercia in Lucca). Since then, Donatello has been called the originator of the putto because of the contribution to art he made in restoring the classical form of putto. He gave putto a distinct character by infusing the form with Christian meanings and using it in new contexts such as musician angels. Putti also began to feature in works showing figures from classical mythology, which became popular in the same period.
