Pellegrini, God the Father among the Cherubin
Capella Michiel, Ognissanti Church, Venice, Italy
The identification of the Father is obvious. The women below can be tentatively identified as Saints Perpetua and Felicity, for several reasons. First, they are paired, like Perpetua and Felicity (but no other women) in the Roman Catholic Litany of the Saints. Second, only one of them is writing and that one has a P on her shoulder. A major section of "The Passion of Saints Perpetua and Felicitas" is written by Perpetua in the first person; no section is attributed to Felicity. Finally, the background appears to be a stylized arena like the one in Carthage where the two women were offered to wild beasts and then put to the sword.
The identification would be more certain if there were an F on the other woman's shoulder, or if there were beasts or swords in evidence — and one wishes there were an explanation for the spike-shaped implement in the hand of the putto between them.
