 In 1573 he moved to Rome to work under Vasari in the Cappella Paolina (with Federico Zuccari) and Sala Regia of the Vatican, where he adopted many of the stylistic traits of Raphael's school and produced perhaps his most famous painting, "The Triumph of Faith over Infidelity".After Vasari's death in 1574, Gregory XIII appointed Sabatini superintendent of works in the Vatican, a post he retained until his own premature death.Sabbatini died in Rome in 1577.
