Bacchanalia

The Bacchanalia were Roman festivals of Bacchus, based on various ecstatic elements of the Greek Dionysia. They seem to have been popular, and well-organised, throughout the central and southern Italian peninsula. They were almost certainly associated with Rome's native cult of Liber, and probably arrived in Rome itself around 200 BC but like all mystery religions of the ancient world, very little is known of their rites.

Livy, writing some 200 years after the event, offers a scandalised, extremely colourful account of the Bacchanalia. Modern scholarship takes a skeptical approach to his allegations of frenzied rites, sexually violent initiations of both sexes, all ages and all social classes, and the cult as a murderous instrument of conspiracy against the state. Livy claims that seven thousand cult leaders and followers were arrested, and that most were executed.

Senatorial legislation to reform the Bacchanalia in 186 BC attempted to control their size, organisation, and priesthoods, under threat of the death penalty. This may have been motivated less by the kind of lurid and dramatic rumours that Livy describes than by the senate's determination to assert its civil and religious authority over Rome and her allies, after the prolonged social, political and military crisis of the Second Punic War. The reformed Bacchanalia rites may have been merged with the Liberalia festival. Bacchus, Liber and Dionysus became virtually interchangeable from the late Republican era onward, and their mystery cults persisted well into the Roman Imperial era.
