Santa Maria degli Angeli e dei Martiri
Antonio del Duca or Lo Duca (Cefalù 1491 – Rome 1564) was the Sicilian friar whose persistent campaign for an official veneration of the "Seven Angelic Princes" was partly answered in the dedication of Santa Maria degli Angeli e dei Martiri, constructed to the orders of Pope Pius IV within the ruins of the Baths of Diocletian.
