Rouault occupied a singular position in twentieth-century European painting, a working religious artist in a secular age, an Expressionist in a country that had little use for Expressionism, and a French modernist whose deepest imaginative sources were medieval rather than avant-garde.
Rouault's early apprenticeship in stained glass was not a brief technical detour but a five-year immersion in one of the oldest crafts of European religious art. His work on the restoration of medieval glass gave him direct, daily exposure to the disciplines of leaded color, heavy linear structure, and the spiritual subjects of the Gothic period, and the resulting visual vocabulary of strong black contour around saturated, jewel-toned color became the basis of his mature painting style.
His subsequent training in Moreau's studio placed him within an unusual teaching environment. Moreau was a Symbolist of independent means and idiosyncratic vision who encouraged each of his students to find a personal direction rather than follow a school style, and the class he produced, with its three most distinguished members each developing a wholly different idiom, is one of the most consequential single classes in the history of modern French painting. The curatorial position Rouault took up at the museum dedicated to Moreau's work after the master's death gave him a permanent professional base and the income to pursue a deeply uncommercial mature style.
That style developed through a sustained engagement with the moral and physical underside of Belle Époque Paris. His paintings of judges, lawyers, prostitutes, and circus performers from the early 1900s onward read as a religious painter's commentary on the institutions of secular society, executed in a heavy, almost archaic visual language that owed nothing to Cubism or Fauvism, the dominant tendencies of his contemporaries. He was a devout Catholic for whom painting and faith were inseparable, and he stated more than once that his ambition was to paint a Christ so moving that those who saw the image would be converted.
His relationship with Ambroise Vollard, formalized in a contract of 1917, gave him the support to undertake major long-term projects. The most important of these was the Miserere et Guerre graphic series, whose subjects range from the betrayal and crucifixion of Christ to the carnage of the First World War, a sustained meditation on suffering, sin, and redemption that has been compared in scope and depth to the great print cycles of Goya and Dürer. He also produced ceramics, tapestries, and theatrical designs, including costumes and sets for Diaghilev's Ballets Russes.
The death of Vollard in a 1939 automobile accident initiated a bitter and prolonged legal dispute with the dealer's heirs over hundreds of unfinished paintings stored in Vollard's premises. Rouault eventually recovered most of the work, and in 1948, in a famous gesture of artistic conscience, publicly burned more than three hundred canvases he believed he could not complete to his own standards. He continued to work into his eighties and died in Paris in 1958, the recipient of a state funeral, one of the rare moments in modern French history when an artist was honored by the Republic in that manner.
