Annibale Carraci also designed the frescos on the short barrel-vault of the chancel, which were executed by Innocenzio Taccone, the first and one of the ablest of Carracci's assistants. They depict the Coronation of the Virgin (central medaillon) and the visions of Sts Peter and Paul, Domine quo vadis and Saint Paul Transported to the Third Heaven (side panels), both set in rich gilded stucco frames. The frame of the central medaillon in held by four stucco putti.
