Gioioso de Chiavelli

Gioioso de Chiavelli (c. 1295–1374/78) was a cleric of the Ghibelline noble Chiavelli family of Fabriano. In 1356 he was made bishop of Camerino, transferred to the see of Penne and Atri in 1360, and returned to Camerino in 1374.

As capitular prior of Fabriano Cathedral in the later fourteenth century he directed its major enlargement, when the apse and tribune were built. He died between 1374 and 1378, when his successor was appointed.
