The triumphal arch of the chancel is crowned with the painted stucco coat of arms of Cardinal Antonio Maria Sauli. The new main altar of the basilica and the redecoration of the arch at the behest of the Genoese cardinal was finished in 1627. The symbol of his family, a displayed eagle is set on an Italian escutcheon decorated with a cherub head and a cross. The coat of arms is supported by two angels portrayed as naked ephebes in an impeccably Classical fashion.
