"The Madonna of the Palafrenieri"
Undoubtedly, it is an atypical depiction of the Virgin for its time and probably has been shocking to some contemporary viewers. The Virgin, with the help of her son, whom she holds, tramples a snake, a symbol of evil or original sin. Saint Anne, whose painting is meant to be honored, is an old, wrinkled grandmother who witnesses this event. Shaky halos crown the rack; the snake bounces off the halo. Mary and Jesus barefoot; Jesus is a completely naked, uncircumcised child. Everything else is a shadow, and the figures become monumental in the light.
Suppose this picture was intended in honor of the grandmother of Christ. In that case, it is unclear how the ungrateful image of her wrinkled appearance in this painting would be perceived as respectful or iconic. According to Bellory, further shock should have come from the revealing bodice of the Virgin Mary. Finally, it can be assumed that the parallel diagonals of the phallus and the feet of Jesus suggest that both are fighting with the snake, and one is metaphorically equal.
