Dario Fo, Italy's foremost practitioner of AgitProp theatre, is one of the world's most versatile theatrical talents: actor, director, playwright, scene and costume designer, dancer, mime, mimic, and political clown. Because of his extensive use of mimicry, masks, and puppets, Fo's theatre is mistakenly characterized as stemming primarily from commedia dell'arte.But commedia satirized social stereotypes, whereas Fo's political satire (broad comedy and highly presentational), originated in the period between the tenth and twelfth centuries, the post-feudal age when the Italian peninsula experienced a burst of political freedom; jesters roamed the land with a repertoire of gags and skits celebrating the end of feudalism, and ridiculing the remaining feudal overlords and the Church. Performing in streets and market places, presenting comic routines consisting of simple language, mime arid mimicry, the feudal jester delighted the common people while awakening them to the tyranny of the nobility.
