While the new plebeian nobility made social, political and religious inroads on traditionally patrician preserves, their electorate maintained their distinctive political traditions and religious cults. During the Punic crisis, popular cult to Dionysus emerged from southern Italy; Dionysus was equated with Father Liber, the inventor of plebeian augury and personification of plebeian freedoms, and with Roman Bacchus. Official consternation at these enthusiastic, unofficial Bacchanalia cults was expressed as moral outrage at their supposed subversion, and was followed by ferocious suppression. Much later, a statue of Marsyas, the silen of Dionysus flayed by Apollo, became a focus of brief symbolic resistance to Augustus' censorship. Augustus himself claimed the patronage of Venus and Apollo; but his settlement appealed to all classes. Where loyalty was implicit, no divine hierarchy need be politically enforced; Liber's festival continued.
