Mortise and tenon joint, with advanced tenon shoulder and mixed cut on front face, and cut square at back. Fig. 138. 1. Slotted joints mitred on both faces, with stub tenon. 2. Slotted joints, mitred at front, cut square at back. 3. Mitred slotted joint with half-dovetail. Mortise and tenon joints with a mixed cut on both faces are fairly simple joints (fig. 136). They are not very frequent, we have found only five examples, ranging from 1436 to the late 15th century. This joint is used in the frame of the Portrait of Gilles Joye (1472). The mortise and tenon joint with the tenon shoulder advanced and a mixed cut on one side only and cut square at the back, is an improved and stronger version of the previous joint (fig. 137). It is frequently used in the second half of the 15th century, in particular for works by Rogier van der Weyden and his followers. It remained in use in Bruges until the mid 16th-century. This joint is found in the Gdansk Last Judgement and the Cologne Nativity .
