Agostino Ciampelli (29 August 1565 – 22 April 1630) was an Italian painter of the Baroque period. He trained with Santi di Tito in Florence, and painted in Rome under Clement VIII, including a Crucifixion for Santa Prassede and a Saint Giovanni Gualberto in its sacristy; Angels on the walls above the choirstalls in the apse of Santa Maria in Trastevere; frescoes of the Stoning of Saint Vitale in San Vitale and further frescoes in the little church of Santa Bibiena; and The Visitation in Sant Stefano di Pescia. At the Basilica of San Giovanni in Laterano, Ciampelli frescoed the walls of the canons' sacristy, the "Sala Clementina".
Agostino Ciampelli was born in Florence, Italy, and grew up with his mother and father. There is little known about his early childhood, such as if Agostino had any siblings or the influences of his environment and how he first got interested with becoming an artist.
Agostino trained in the studio of Santi di Tito who was one of the leading artists of the Counter Reformation in Florence. Under Santi di Titio’s schooling Agostino learned the principles of a conservative and a devotional manner in the treatment of religious subjects. Agostino was said to be a true artistic heir to Santi di Tito and Agostino’s work was very influenced by his mentor.
Agostino was admitted into the Accademia del Disegno in Florence in 1585. Some of his earliest known works include paintings for a temporary triumphal arch at the entry of Christina of Lorraince into Florence in 1589. These paintings were constructed by Santi and his pupils.
