Hardly any other mythical creature has enjoyed the ubiquity of the clown: “There are few other myths such as this one about which it can be affirmed without any doubt that they involve the most ancient modes of human expression,” wrote Paul Radin in his famous essay on the figure of the clown among primitive American Indians. “There are few myths which have retained their original characters with so few changes.” The character of the Fool, the Jester, the Joker appears in a clearly identifiable fashion in the most primitive as well as the most highly cultivated groups: among the Greeks as well as the Chinese; in Japanese civilization as well as the Semite world. The medieval juggler is the embodiment of this figure of many aspects who perdures in the theater, especially puppet theater, and in the guise of the circus clown.
