The opulent strength of this chalice is achieved through a balance of the richly colored and exquisitely drawn enamels with the finely worked silver-gilt leaf forms and moldings. On the base are the Crucifixion, the Virgin, and Sts. John the Evangelist, Louis of Toulouse, John the Baptist, and Anthony of Padua (?). Seraphim decorate the spandrels and collar above. On the knop are Sts. Michael, Francis, Mary Magdalene (?), Catherine of Alexandria (?), and Elizabeth of Hungary (?). The inscription refers to the donor, Brother Peter of the Penitentiary, and the town of Sassoferrato in Umbria (Marche) and warns that the chalice should not be sold or destroyed. Brother Peter was appointed to the Sacred Order of the Penitentiary by Pope Benedict XII in December 1341. The cup is a replacement, perhaps of the 15th century.
