Detail of the the fresco cycle
by DEODATO DI ORLANDI, Fresco
In the lower part of the large fresco cycle are portraits of Popes, from St Peter to John XVIII (1303); the intermediate portion has thirty panels with Stories of St Peter’s Life (as well of those of St Paul, Constantine and St Sylvester), similar to those in the Old St Peter’s Basilica and to Cimabue’s work at San Francesco in Assisi.
