A lizard drowned in a man's urine has the effect of an antaphrodisiac upon the person whose urine it is; for this animal is to be reckoned among the philtres, the magicians say. The same property is attributed to the excrements of snails, and to pigeons' dung, taken with oil and wine. The right lobe of a vulture's lungs, attached to the body in the skin of a crane, acts powerfully as a stimulant upon males: an effect equally produced by taking the yolks of five pigeons' eggs, in honey, mixed with one denarius of hog's lard; sparrows, or eggs of sparrows, with the food; or by wearing the right testicle of a cock, attached to the body in a ram's skin. The ashes of a burnt ibis, it is said, employed as a friction with goose-grease and oil of iris, will prevent abortion when a female has once, conceived; while the testes of a game-cock, on the other hand, rubbed with goose-grease and attached to the body in a ram's skin, have all the effect of an antaphrodisiac: the same, too, with the testes of any kind of dunghill cock, placed, together with the blood of a cock, beneath the bed. Hairs taken from the tail of a she-mule while being covered by the stallion, will make a woman conceive, against her will even, if knotted together at the moment of the sexual congress.[1] If a man makes water upon a dog's urine, he will become disinclined to copulation, they say.

A singular thing, too, is what is told about the ashes of a spotted lizard—if indeed it is true—to the effect that, wrapped in linen and held in the left hand, they act as an aphrodisiac, while, on the contrary, if they are transferred to the right, they will take effect as an antaphrodisiac. A bat's blood, too, they say, received on a flock of wool and placed beneath a woman's head, will promote sexual desire; the same being the case also with a goose's tongue, taken with the food or drink.
