“For my own part I like the usual custom and the ordinary method best: the man should lie upon the woman, who is on her back, breast to breast, stomach to stomach, pubis to pubis, piercing her tender cleft with his rigid spear. Indeed what can be imagined sweeter than for the woman to lie extended on her back, bearing the welcome weight of her lovers’ body, and exciting him to the tender transports of a restless but delicious voluptuousness? What more pleasant than to feast on her lovers’ face, his kisses, his sighs, and the fire of his wanton eyes? What better than to press the loved one in her arms and so awake new fires of desire, to participate in amorous sensations unblunted by any taint of age or infirmity? What more favorable to the delight and enjoyment of both than such lascivious movements given and received? What more opportune at the instant of dying a voluptuous death than to recover again under the revivifying vigour of burning kisses? He who plies Venus on the reverse side, satisfies but one of his senses, he who does the same face to face satisfied them all.” (Dialogue VI.) Ovid, the Master of Loves’ Mysteries, invites pretty women to take this posture by preference: “See you reckon up each of your charms, and take your posture according to your beauty. One and the same mode does not become every woman. You are especially attractive of face; then lie on your back.” (_Art of Love_, III., 771-773.) This posture is by no means limited to one mode. The woman lying on her back, the rider may clasp her between his legs, or she may receive him between hers. Yet another position may be adopted, according as the woman lie back with legs stretched wide apart or with the knees raised. It is this position,—lying on her back with legs wide apart, that Caviceo asks Olympia to assume for making Love: “I do not wish you”, he says, “to work your buttocks, or to respond with corresponding movements to my efforts. Neither do I wish you to lift your legs up, whether both at once, or one after the other, when I have mounted you. What I do wish you to do is this: First stretch your thighs as far apart, open them as wide as a woman well can. Offer your vulva to the member which is going to pierce it, and without altering this position, let _me_ complete the work.... Count my thrusts one by one, and see you make no mistake in the total” (Aloysia Sigaea, Dialogue V.). Would you see a representation of this? Take the tale _Félicia ou mes fredaines_, part II., ch. xxv, and look at the plate facing the text. The other position, in which the woman is lying with her knees raised, is the one which Callias makes Tullia take:
