Tomb slab of Pope Martin V
by MICHELOZZO DI BARTOLOMEO, Bronze
Pope Martin V (1369-1431), born Oddone Colonna, was the head of the Catholic Church and ruler of the Papal States from 1417 to his death. His election effectively ended the Western Schism (1378–1417). He was buried in the Basilica di San Giovanni in Laterano where he held also the office of the dean.
Michelozzo’s authorship of the tomb is not universally accepted.
