“ The Bacchanalia are rigidly prohibited: if any one, Roman, Latin or ally, considers himself under a religious obligation bacanal habere, he can only do so by obtaining permission from the praetor urbanus, confirmed by a vote of the senate in which not less than 100 have taken part. No priest, president, or common purse is allowed, nor any kind of common vow. Not more than two men or three women (five in all) should celebrate the rites, except by special permission. ”
