Italian painter, sculptor and architect. He was active in Rome during the papacy of Pope Gregory XIII (1572-1585). In the Roman church of Sant'Atanasio dei Greci, which was founded by Gregory, there are two altarpieces by Traballesi, an Annunciation, and a Christ among the Doctors, while in the Greek Pontifical College of Saint Athanasius, next to the church, are more of his paintings, with Apostles, Fathers of the Church, and a Crucifixion, which were once parts of the iconostasis of the church itself. In the Town Hall of Tivoli, anciently called Tibur in Latium, are two frescoes painted by Traballesi in 1574, showing scenes of The Mythic Foundation of Tibur. He died in 1588 in Mantua, where he was working as an architect for the duke Vincenzo Gonzaga. His brother Bartolomeo Traballesi was an assistant of Vasari. //
