The present relief must once have formed part of a large altarpiece, presumably on one of the wings of a triptych, flanking the central image. It appears to represent two female martyrs, although one of the attributes, possibly a pillar, remains unclear.
Stylistically, the relief is typical of South German wood sculpture of the late 15th and early 16th century, and more specifically of the region of Franconia. The pointed chins and the down-turned outer corners of the eyes betray the influence of Tilman Riemenschneider (1460-1531), who dominated the world of sculpture in Franconia in the early years of the 16th century. One can compare the facial types here to works securely attributed to Riemenschneider such as his Virgin and Child on the Crescent Moon (New York, op. cit., no. 22, pp. 250-252.)
