Storia del Duomo di Orvieto
Storia del Duomo di Orvieto is a 1791 history of the cathedral at Orvieto, Italy, written by Guglielmo Della Valle and published in Rome by the Lazzarini press for readers of church architecture. Its pictures are engraved armorial bookplates and emblems, with a coat of arms flanked by putti or lions, a papal tiara and crossed keys, and a Borghese-style seal with laurel borders, showing how heraldic ornament can frame a title or emblem.
