Alabaster carving and trade took on industrial proportions in England between the mid-14th and the early 16th centuries. Altarpieces with scenes from the Life of Christ and the Virgin were particularly popular. A relief with the Seat of Mercy, where the Christ on the cross is positioned between his Father's knees, often made up the central, slightly larger panel of these altarpieces. The Swansea Altarpiece in the Victoria and Albert Museum (inv. nos. A.89:1 to 8, 10 to 15-1919) is a rare survival of a complete altarpiece in its original frame; compare the central panel to the present lot. Even closer comparison can be found in a relief of the Holy Trinity, sold at Sotheby's New York, 26 January 2012, lot 256. The present lot is distinguished by the amount of surviving gilding and polychromy.
