Part of a triptych with the Last Judgment

Christ is depicted as a judge at the Last Judgement. Flanked by the Virgin Mary and John the Baptist, he is showing his wounds. In the background, two angels hold the instruments of the Passion. In the trefoil at his feet, the dead are rising again. The edges at the top and sides, and the rough kerf at the lower edge show that there must have been another painting below this one.
