Italian sculptor (active 1447–1464 in Rome)
Reliquary Tabernacle of the Head of St Andrew c. 1463
Grotte Vaticane, Rome
Pius II commissioned Paolo Romano and Isaia da Pisa to make a tabernacle for St Andrew's head. The reliquary tabernacle was destroyed when the new St Peter's was built, leaving only remnants of its original sculpture. This relief is from the upper faces of the tabernacle.
