LAMBERTI, Niccolò di Piero

Tomb of Pope Alexander V

1424
Terracotta
San Francesco, Bologna

Alexander V (Peter of Candia or Peter Phillarges, c. 1339-1410) was a pope elected by the Council of Pisa during the Western Schism (1378–1417). He reigned briefly from June 26, 1409 to his death in 1410, in opposition to the Roman pope Gregory XII and the Avignon pope Benedict XIII. In the 20th century, the Catholic Church reinterpreted the Western Schism by recognizing the Roman popes as legitimate. Gregory XII's reign was extended to 1415, and Alexander V is now regarded as an antipope.

His terracotta grave in the left nave of the church San Francesco in Bologna was built in two installments, in 1424 and then in 1483. The upper part was made by Niccolò di Piero Lamberti, the tomb was completed in 1483 by Sperandio Savelli (c. 1425-c. 1504).
