Votaries initiated in the orgies of Dionysus ran about in goat-skins, mangling hounds in Bacchic frenzy

Accordingly during the whole period of his [Valens'] reign the altar fire was lit, libations and sacrifices were offered to idols, public feasts were celebrated in the forum, and votaries initiated in the orgies of Dionysus ran about in goat-skins, mangling hounds in Bacchic frenzy, and generally behaving in such a way as to show the iniquity of their master. When the right faithful Theodosius found all these evils he pulled them up by the roots, and consigned them to oblivion.
