To the right of the entrance is the funerary epitaph of Vannozza dei Cattanei, moved here from her tomb in Santa Maria del Popolo in obscure circumstances. She was the mistress of Cardinal Rodrigo Borgia before his election as Pope Alexander VI (r. 1492-1503). She was the mother of Cesare, Lucrezia, Giofrea and Giovanni Borgia, and their names were recorded with pride in the inscription on the tomb. Because of this, it is thought that enemies of the Borgias later looted the tablet, brought it here and used it as paving for the portico.
