Leaves from Laurent d’Orléans, La Somme le roi
Underdrawing, showing as thick grey lines through lighter pigments, plays an important role in the modelling of folds. It is best seen in the light pink cloaks of the female personification of Chastity and of Potiphar’s wife in MS 368, where the effect is further enhanced by the faded organic pink pigment. The infrared images of both fragments further reveal the underdrawing present in all the draperies. A pentimento in the form of a quadrilobe decorative pattern, which was drawn but never painted, is apparent in the central area of Noah’s ark in MS 192.
