The right nave features the epistle-side organ by Pietro Nachini (1751) in the wind-instrument gallery where 20th century canvasses represent the Conseceration of Bishop Hermagoras by Saint Peter, taken from the 16th century works by Giovanni Antonio de Sacchis, known as il Pordenone. These original works were lost in the 18th century after the restoration of the 16th century organ and then reproduced on canvas in line with the canvasses on the parapet representing Hermagoras in front of the tribunal at Sebaste, Hermagoras in prison pays a visit to Alexandria, The Flagellation, the Sebaste Tribunal Sentences the Saints, he Burial of Hermagoras and Fortunatus and the Baptism of the Aquiliea Virigns. The original paintings the Burial of Hermagoras and Fortunatus and the Baptism of the Aquiliea are conserved in the upper rooms of the Museum.

Alongside the monument to bishop Zaccaria Bricito by Luigi Minisini (1854).
