of these paintings frequently recall the works of Henri Rousseau, an artist Léger greatly admired and whom he had met in 1909. They also share traits with the work of Le Corbusier and Amédée Ozenfant who together had founded Purism, a style intended as a rational, mathematically based corrective to the impulsiveness of cubism. Combining the classical with the modern, Léger's Nude on a Red Background (1927) depicts a monumental, expressionless woman, machinelike in form and color. His still life compositions from this period are dominated by stable, interlocking rectangular formations in vertical and horizontal orientation.
