Pope Fabian
During the restoration in 1953, the team led by Professor Franco Milani found some frescoes dating to the fifteenth century. On the left wall there are depictions of Pope Fabian and Saint Sebastian, while on the right side there are depictions of Saint Ambrose, Marcellina and Satyr. These frescoes were damaged by moisture and covered with layers of lime. The damage was also observed to undermine the pilaster. After restoration the frescoes were partly preserved. Classic iconographic representations of Saint Ambrose are of an old man, but in this church's frescoes both the bishop and Saint Sebastian are represented as young people. The frescoes have a gothic style that also characterizes the altarpiece. The author was probably influenced by artistic trends of northern Europe as well as by Giotto.
