Virgin Mary and Christ interceding for the town of Piacenza

On a cloud supported by angels, the Resurrected Christ and Virgin Mary look at the Father with an interceding gesture for the below town of Piacenza, dotted with churches and bell tower (Palazzo Farnese also stands out). The division of the space in two dimensions, human and divine, united by a band dedicated to the mediating Saints replaced here by Mary and Jesus, is a constant in Baroque altarpieces.
