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

CHAPTER VII 142 In other words, the slotted joint is the main form of joint used in the 16th century. But it is not a new invention. In its simple form, mitred on both sides, we already find it in the Braque Triptych of Rogier van der Weyden (Paris, Louvre). 4. Half-lap joints (fig. 19: 28-29 ) We found 2 cases of this joint: Bruges, GM , no. 17 (Adriaen Isenbrant, Triptych of the Virgin and Child with St John and St Jerome ); Bruges, SJH , no. 21 (Pieter Claeissens the Younger, Carrying of the Cross ). This relatively weak joint is rare. We have not taken into account here those cases where it is used for the lower parts of frames, such as Frans Francken II (attributed to), Crucifixion (Leuven, MM , no. 13 and Leuven, MM , no. 14) . In the case of the wings of the triptych by Adriaen Isenbrant, the joints are not pegged. Nor are they in the frame of the Pieter Claeissens work, where the hanging fittings fulfil this role.
