The Four Seasons is composed of thousands of inlaid chips of glass and stone from France, Belgium, Italy, and Israel, as well as native Chicago brick in over 250 colors that cover a large-scale rectangular structure. It blends scenes of the changing seasons with the Chicago cityscape and features some of the familiar images of Chagall's paintings, including birds, fish, flowers, and pairs of lovers. Across the surface of the mosaic, the artist included four variations on the theme of the sun—with a swirling rainbow, as a petal disc, as a brilliant sunflower, and as a colorful wheel—that mark the span of a year, while figures engage in seasonal activities.
