The Three Hares is a circular motif found at sacred sites from China to England. It consists of three hares chasing each other in a circle. Used as early as the 6th century in Chinese cave temples, the symbol appears to have spread along trade routes. It appears in architecture and on headstones and in Jewish, Islamic, Buddhist, and Christian art. It is a perceptual puzzle in that, although each rabbit has two ears, the total number of ears pictured is only three. How is this illusion achieved? Discuss
