This article traces a logical and political thread leading from the theory of revolt in Furio Jesi's 1969 Spartakus to his later work on festivity and the “mythological machine model.” It opens by arguing that the humanist model that frames Jesi's early efforts to disarm the allure of insurgent violence, sacrificial mythology, and Manichaean politics generates insoluble aporias that spur the development of a radically different approach to the study of myth and human nature. Next, it shows how Jesi's studies (...) on festivity from the 1970s redound upon and transform the theory of revolt in Spartakus, bringing this theory more in line with current epochal conditions. In doing so, they presage and lay the groundwork for the theory of destituent power developed in recent decades by Giorgio Agamben. (shrink)
