This almond-shaped enamel plaque depicts the half-length figure of an angel inscribed in a medallion. A nearly identical plaque in the cathedral treasury of St. Martin at Orense in Galicia (Northern Spain) suggests that this plaque once formed part of a large altar frontal commissioned by Bishop Alfonso of Orense (reigned 1174–1213). Fifty-three enameled plaques of this important ensemble are still preserved at the Cathedral of Orense. Others, including this one, were possibly removed during the Napoleonic era.
