Cardinals Federico and Paolo Emilio Cesi, who were brothers, are buried here and have matching memorials in the side walls by Guglielmo della Porta. Paolo died first, in 1537, and his monument is to the left. It is inserted into a shallow arched niche, and has a pair of Corinthian columns in pavonazzetto marble supporting a triangular pediment. The frieze of the entablature, the pediment tympanum and the background revetting are all in a white-veined black marble. On top of the pediment a pair of putti hold the cardinal's heraldry, and a winged putto's head with swags is below the entablature.
