All this was actually represented in Paris, 1791, on the stage of a theatre, where, according to the author of the _Gynaeology_ III., 423, a man completely naked had connection with a woman as naked as himself, both representing savages, accompanied by the plaudits of both sexes. There is however nothing new under the sun. With the Romans it had long been customary, after the public games were finished, to bring prostitutes into the arena, and set them to work, so that the spectators might have an opportunity to perform what they had been looking at with greedy eyes; a herald proclaimed what was to come. Tertullian, _De Spectaculis_, ch. 17: “Prostitutes, the victims of public incontinence, are brought upon the stage, shamefaced with respect to the women only; to the men they were known; they are exposed to the laughter of all, high and low; their dwellings, their prices, even their recommendations were proclaimed by the crier.” Isidorus, _Origines_, XVIII., 42: “The theatre is like a brothel; when the games are over, public women are prostituted there.” The rape of the Sabines described in Livy (II., 18) would seem to have been a not dissimilar form of amusement: “In this year young Sabines in Rome having, in the midst of the games, abducted some prostitutes, the tumult ensuing thereupon degenerated into a riot, in fact nearly into a battle.” Footnote 131: Observe the subtlety of the expression adopted by the poet: “offers her buttocks to an ass to get on them.” Juvenal knows that a woman has no chance to have an ass’s mentula in her except by turning her back to the beast. Footnote 132: Plato, _Symposium_ (Works, Zweibrücken edition, vol. X., p. 205) imagines another origin; in the passage where he relates the celebrated fable, according to which Jupiter had cut the men in halves, he says: “As to those women who are halves of women, they are not much harassed by desires after men; but are much more given to amuse themselves with women; the hetairistriae descend from their category.” Footnote 133: Another use of these leathern engines has been noted in ch. II. Footnote 134:
