ritual clowning in primitive religions
See esp. L. Makarius, "Ritual Clowns and Symbolic Behavior," Diogenes No. 69 (Spring 1970). Also V. R. Bricker, Ritual Humor in Highland Chiapas (Austin & London: Univ. of Texas Press, 1973), which deals with archaic Meso-American clowning incorporated into Christian festivals, but stops short at the social-censure aspect of ritual humor.
