Both outside and inside the Orvieto Cathedral, artistic decoration attests to the deep reverence the citizens of Orvieto had for the Virgin Mary and confirms that her cult thrived in Orvieto. While most cathedral projects saved the facade decoration for last, at Orvieto, art honoring the Virgin appeared there first, publicly proclaiming reverence to her. By 1330, Lorenzo Maitani crowned the central portal with a life-size marble sculpture of the Virgin and Child seated under a bronze canopy and flanked by angels; a backdrop of Marian mosaics was underway. Interior decoration began in the Cappella Maggiore with the resplendent monumental stained-glass window by Giovanni di Bonino, completed in 1334; Ugolino di Prete Ilario reiterated the Orvietan reverence for the Virgin in a comprehensive narrative fresco program, completed in 1384.
