Roma Ex Ethnica Sacra Sanctorvm Petri, Et Pavli Apostolica Praedicatione Profcso Sangvine
A 1668 Roman church history by Fioravante Martinelli, printed in Rome for a learned Catholic readership, documenting the city's sacred sites and martyrs linked to Saints Peter and Paul. The picture is an engraved roundel pairing a bearded cardinal's bust in profile with a Latin inscription above a small church facade dated MDXXXII, a clean model for framing portrait medallions above architectural elevations.
