Stars is a wood engraving print created by the Dutch artist M. C. Escher in 1948, depicting two chameleons in a polyhedral cage floating through space. Although the compound of three octahedra used for the central cage in Stars had been studied before in mathematics, it was most likely invented independently for this image by Escher without reference to those studies. Escher used similar compound polyhedral forms in several other works, including Crystal (1947), Study for Stars (1948), Double Planetoid (1949), and Waterfall (1961).
