Imposing gilded copper, embossed, engraved, and enamelled pax-board with rock crystal cabochons and gemstones. Italy. Circa 1400. Measurements: 18,4 x 11,3 cm.   A marvellous piece of liturgical metalwork. With an architectural structure, in the centre, the figure of Saint Gregory as the Pope giving a blessing is affixed there, flanked by two slender turned columns and under a Gothic archway with pinnacles. The background is adorned with a delicate white enamelled copper plate with highlights in gold and blue. The entire pax is embellished with multiple rock crystal cabochons and green and red gemstones. It has some flaws. This lot has been imported, therefore its exportation permit from the Spanish Ministry of Culture is guaranteed.
