17 Or if the things which we say are not so declare, say yourselves— those effeminate and delicate men whom we see among you in the sacred rites of this deity— what business, what care, what concern have they there; and why do they like mourners wound their arms and breasts, and act as those dolefully circumstanced? What mean the wreaths, what the violets, what the swathings, the coverings of soft wools? Why, finally, is the very pine, but a little before swaying to and fro among the shrubs, an utterly inert log, set up in the temple of the Mother of the gods next, like some propitious and very venerable deity? For either this is the cause which we have found in your writings and treatises, and in that case it is clear that you do not celebrate divine rites, but give a representation of sad events; or if there is any other reason which the darkness of the mystery has withheld from us, even it also must be involved in the infamy of some shameful deed. For who would believe that there is any honour in that which the worthless Galli begin, effeminate debauchees complete?
