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

catalogue 338 The polychromy is highly coloured. On the outside: rail: greenery on the flat part; the inclined sill is painted red, with a text under the figure of Christ and in the draperies of Robrecht de Clercq’s garment. For the stiles and the curved parts, the blue cavetto moulding with round and diamond-shaped little flowers is edged on the panel side with a red fillet and, on the frame side, with various fillets (brown, red, ochre-yellow). Otherwise, the flat areas are grey in imitation grey stone, with trompe-l’œil joins. Robrecht de Clercq is painted on the imitation red porphyry background and seems to have been added onto the original background after 1515. Original polychromy on the inside of the diptych, black and gold text on the lower rail of the panel with the Virgin: SALVE REGINA MISERICORDI[A]E ; little black line where the panel and the frame meet in the wing of the Virgin only.
