O.OTP0048.I Bibliography: Maertens 1939, 97, no. 36. Panels: the central panel, consisting of three boards, is held against the rebate with old forged nails. Each wing consists of two boards, slotted into the groove of the frame. Frames: central frame: rebated; side frames: grooved. Wings: slotted joints, strengthened with a single peg, cut square on the outside and mitred on the inside. The two curved parts of the central frame are assembled to the shorter stiles with longitudinal mortise and tenon joints, reinforced in each case with a peg. The construction was not intended for hanging, and the curved rails have split at different places, and been repaired at the back with iron fittings. The black and gold polychromy is redone, but seems to be a repetition of the underlying layer of the same disposition.
