Like all true fresco decoration, the two large paintings of "Jacob wrestling with the Angel" and "Heliodorus driven from the Temple" do not attempt to give the illusion of plastic life, or of an opening cut through the wall, but duly accentuate the flatness of the surface. The scale of colour adopted for this admirable decoration aims, without the least sense of monotony or dulness, at the exquisiteness of the greens and greys of a fine panel of faded Flemish tapestry, and has nothing in common with the rich, glowing palette which Delacroix had inherited from Rubens and the Venetian colourists. The tapestry-like effect is particularly noticeable in the treatment of the trees which are so important a feature in the composition of "Jacob wrestling with the Angel," the figures being comparatively small in scale, though by no means subordinate to the landscape. Nothing could be more impressive than the contrast of the terrific muscular exertion of Jacob and the easy grace with which it is made ineffective by his invincible supernatural opponent. The group is one of the noblest creations of modern art--worthy of the brush of a Pollaiuolo or a Signorelli. In the "Heliodorus" the accidents of Nature's architecture are replaced by the equally imposing but deliberate and formal lines of the architecture created by human builders. The general disposition of the design is not unlike that of the earlier "Justice of Trajan"; but there is this significant difference between the earlier work and the St. Sulpice fresco, that the very first glance reveals the essentially human element in the first, and the irresistible force of the supernatural in the second. The tempestuous, sweeping onrush of the two flying angels contrasted with the calm consciousness of all-conquering strength expressed not only in the mounted heavenly messenger but in the very action of his noble horse--the horses in Delacroix's paintings invariably reflect the mood of the drama or tragedy that forms the subject of the picture--are a pictorial conception of unsurpassed grandeur. The only unsatisfactory part of the St. Sulpice decoration is the ceiling, where St. Michael is depicted overthrowing the Demon. Probably the execution of this oval composition was almost entirely the work of assistants, as Delacroix's failing health, aggravated by lead poisoning caused by the extensive use of white of lead paint in his large decorations, would not have allowed him to work under such fatiguing conditions as are unavoidable in painting a ceiling _in situ_. ===================================================================== PLATE VIII.--FAUST AND MEPHISTOPHELES (In the Wallace Collection)
