On the right wall are the statues of three of the younger generation of the Frangipani family: Muzio (1588), the son of Mario, and his two sons, Roberto (1622) and Lelio (1604). These statues are attributed to the Bolognese sculptor Alessandro Algardi and are dated to between 1630 and 1640. On either side of the altar is a marble relief with the Frangipani coat of arms.
