In 1757 the Lercari family restored it as a mortuary chapel for themselves. Apparently the 5th century apse conch mosaic had already fallen off. The conch now has diapered coffering in three sectors, separated by a pair of wide ribs with rosettes. A pair of columns in a bright red mottled stone flank the altarpiece. The round-headed altarpiece in a yellow marble Baroque frame depicts Christ crowning the two martyrs.
