 Remarkable iconographic peculiarity is the fact that the Virgin of Mercy is depicted on a throne, with the Child in his arms and that the two registers depict dead figures and, below, alive, but with a skull at the center to indicate the transience of life.On the left of this scene is still visible the image of St. Peter bishop, owner of the building, sitting on a bench and with the attribute of the keys.It is a cycle of considerable stylistic level and of great interest, also iconographic, with overabundance of elegant cartouches, sometimes furnished with a colored initial.
