The Virgin Mary and John the Evangelist are shown on either side of the crucified Christ. On the wings, the donor and donatrix have unidentified coats of arms, partly rubbed out, with the letters 'W B' associated with the donor. In the background of the wings: left, the Way to Calvary, right the Resurrection.
The Archangel Gabriel was originally on the reverse of the left wing, and the Virgin Annunciate on the reverse of the right wing.
