Livy, Ab Urbe Condita 39.8
“Then Hispala divulged the origin of the rituals. First, in the beginning, the shrine was the province of women and no man was permitted to enter. They kept three days set apart in a year when people could be admitted into Bacchic rites during the day. Married women were typically made the priests in turn.
Paculla Annia, priestess from Campania, changed everything at an alleged indication from the gods. For she also initiated men, her own sons, Minius and Herrenius Cerrinius, into the rites and turned it into a nighttime ritual instead of a day one, substituting five days of rituals in a single month for three in a whole year.
Since the time when the rituals were mixed in this way with men and women together and the rituals happening at night, no kind of crime or vice has been omitted from them. There were more rapes of men committed against other men than women. And those who were less eager for assault or rather sluggish to commit crimes, were offered up in the place of sacrificial animals.
To consider nothing a sin, this was the greatest achievement of religion among them. Men who seemed like they were out of their mind would provide prophecies by madly shaking their bodies. Married women in a Bacchant’s dress and with hair untied would run to the Tiber with burning torches in their hands and when they immersed them in the water they would come out still burning because of the treatment of sulfur and calcium upon them.”
Tum Hispala originem sacrorum expromit. primo sacrarium id feminarum fuisse, nec quemquam eo virum admitti solitum; tres in anno dies statos habuisse, quibus interdiu Bacchis initiarentur; sacerdotes in vicem matronas creari solitas. Pacullam Anniam Campanam sacerdotem omnia, tamquam deum monitu, immutasse: nam et viros eam primam filios suos initiasse, Minium et Herennium Cerrinios; et nocturnum sacrum ex diurno, et pro tribus in anno diebus quinos singulis mensibus dies initiorum fecisse. ex quo in promiscuo sacra sint et permixti viri feminis, et noctis licentia accesserit, nihil ibi facinoris nihil flagitii praetermissum. plura virorum inter sese quam feminarum stupra esse. si qui minus patientes dedecoris sint et pigriores ad facinus, pro victimis immolari. nihil nefas ducere, hanc summam inter eos religionem esse. viros, velut mente capta, cum iactatione fanatica corporis vaticinari; matronas Baccharum habitu crinibus passis cum ardentibus facibus decurrere ad Tiberim, demissasque in aquam faces, quia vivum sulpur cum calce insit, integra flamma efferre.
