Chagall's early life left him with a "powerful visual memory and a pictorial intelligence", writes Goodman. After living in France and experiencing the atmosphere of artistic freedom, his "vision soared and he created a new reality, one that drew on both his inner and outer worlds." But it was the images and memories of his early years in Russia that would sustain his art for more than seventy years. According to Cogniat, there are certain elements in his art that have remained permanent and seen throughout his career. One of those was his choice of subjects and the way they were portrayed. "The most obviously constant element is his gift for happiness and his instinctive compassion, which even in the most serious subjects prevents him from dramatization...." Musicians have been a constant during all stages of his work. After he first got married, "lovers have sought each other, embraced, caressed, floated through the air, met in wreaths of flowers, stretched, and swooped like the melodious passage of their vivid day-dreams. Acrobats contort themselves with the grace of exotic flowers on the end of their stems; flowers and foliage abound everywhere." Wullschlager explains the sources for these images. For him, clowns and acrobats always resembled figures in religious paintings.... The evolution of the circus works... reflects a gradual clouding of his worldview, and the circus performers now gave way to the prophet or sage in his work—a figure into whom Chagall poured his anxiety as Europe darkened, and he could no longer rely on the lumiére-liberté of France for inspiration.
