Thie columns support two little red marble Doric pillars holding up a segmental pediment. In between the pillars are two angels holding a black globe with golden rays, and on the globe in gold are the initials IMAS for the names Iesus and Maria. Two more angels flank this composition, and two putti sit on the pediment. The angels holding the globe are by Pietro Paolo Naldini, for whom angels were a speciality, and the others are by Francesco Cavellini.
