catalogue 306 9. Anonymous, Triptych of St Christopher. Closed: St Anne with the Virgin and Child ; St John the Baptist. Open: wings: St Jerome and St Anthony , c. 1500 Inv. no. 0024 Provenance: acquired before 1902. Bibliography: De Coo 1978, 96; Mund et al. 2003, 378-401. Jozef Vynckier, report on dendrochronology, 10 January 1997 (KIK-IRPA, restoration file no. 1996.05963); Catherine Eyckelberg-Van Heuvel, restoration report, 2000 (KIK-IRPA, restoration file no. 2000.07063). Panels: central panel: two radially-cut vertical boards, ± 0.4 cm thick on the left and right edges and thicker towards the centre butt-join, which is covered with a non original strip of canvas. Bevels at the top and bottom. Reverse carefully planed and covered with a thin layer of black paint. The central panel was inserted in the grooved frame before painting. The unpainted edge is 1 to 1.2 cm wide. Dendrochronological examination shows the two boards to have come from a tree from the Baltic region. The tree could have been felled at the earliest around 1474. Frames: the frame of the central panel is modern, as are the hinges. Remains of the nails of the original hinges are visible on the X-radiograph of the wings. On the upper edges of the wings: remains of swivel hooks. At the bottom, the original closing hooks have been recycled on the new frame. Wings: integral frames; planed flat on the outsides. On the inside: mouldings on three sides and an inclined sill at the bottom. The black and gold polychromy is an overpainting.
