Frames and supports in 15th and 16th-century Southern Netherlandish painting

catalogue 326 Profile of the lower rail The X-radiograph reveals the presence of various metal elements, some definitely original, some possibly so, others that have been added by restorers. The three or four nails in each of the three sides (which remain in their original state) appear also to be original. One can suppose that they served, from the outset, to nail onto the side the canvas that covers the support on the Coronation side. The ironwork element on the left side of the frame may be original. It could be the blade of a hinge, indicating that the two-sided panel is a wing closing a piece of furniture or an altarpiece. Several non-original nails serve to fix the wooden inserts, to attach the lower rail, and to provide other reinforcement.
