"By virtue of its substance, very similar to that of charcoal, the pastel was for Redon, at this period, certainly an intermediate state between drawing and painting. Above all, he was to find in it, without deviating from a technique that was familiar to him, the encouragement to overcome the distrust that color still seemed to arouse in him. Nevertheless, he did not immediately utilize it for the mysterious, personal themes that made the originality of his drawings so engaging." Bibliography and index of illustrations.
