Sextus Empiricus, Adversus Mathematicos 6.8
Thus Pythagoras, when he once observed how youths who had been filled with Bacchic frenzy by alcoholic drink differed not at all from madmen, exhorted the flute-player, who was joining them in the carousal, to play his aulos for them in the spondaic melos. When he thus did what was ordered, they suddenly changed and became as temperate as if they had been sober even at the beginning.
