Lee Johnson's catalogue raisonne of Delacroix's paintings, published in three instalments of two volumes each from 1981 to 1989, has become the point of reference for all subsequent Delacroix scholarship; its authority is absolute, and it is unlikely ever to be superseded. Its unparalleledcontribution has been universally recognised, and in France it is considered the definitive work on the subject. The Fourth Supplement takes into account the numerous findings which have emerged since the Third Supplement was published in 1993. It contains not only relevant information from therecently discovered archive from the descendants of Delacroix's heir and valuable new documentary material, but also many new paintings, of which a significant number are illustrated. As the world authority on Delacroix, Lee Johnson is regularly consulted by dealers and collectors alike: thissupplement makes an invaluable addition to an already invaluable catalogue.A reprint of the Third Supplement, currently only available as part of the reprinted two-volume set of Volumes III and IV, is also included.
