In one Hindu erotic manual, a kind of Rake’s Progress entitled The Harlot’s Guide, certain ingredients are enumerated as contributing to the potency of philtres. Included in the items are fish soup, ghee, and indigenous herbs. * * * * * In former times, in France, a dish of the testes of a kid or a bull or a fox or a hare would be set before a man who intended to embark on amatory ventures. * * * * * Love stimulants may be both material and psychic. They may have physiological impacts that result in amatory capacity, or they may heighten and arouse the emotional awareness and sensitivity, with similar results. Among the medieval investigators, philosophers, and alchemists and occultists, Albertus Magnus held a dominant position. He had a perception of scientific method, yet he also dealt in unwarranted and legendary fantasies. He wrote on physiology and astronomy. He investigated plant and animal life. He equated the characteristics and properties of certain stones, certain metals, certain creatures, with corresponding human traits and faculties. He felt that such stones, or the extraction of certain animal organs, would be conducive to the realization of the virtues of these minerals or viscera in relation to the human being. The lion’s bravery resides in the lion’s heart. Hence the eating of the heart, by a kind of sympathetic transference, will render the human consumer equally courageous. So the procedure extends throughout the entire amatory field. Certain animals and birds, as the pigeon and the ass and the goat and the bull, are known for their lubricity. The testes, therefore, and the genitalia of such animals will correspondingly endow the man who consumes them with equally intense capacity. Certain formulas, particular invocations and ritualistic procedures, diagrams and symbols and periapts will all contribute to the efficacy of the rite. Thus, to stimulate desire in either sex, the genitalia of the animals of the opposite sex are consumed. In the nests of eagles are found stones called echites. Worn on the left arm, these stones promote erotic sensations. To ensure erotic continuance, the marrow of a wolf’s left foot is advised. This is mixed with chypre and ambergris and the resultant unguent is rubbed on the object of affection. Like a culinary direction, but usually with less promptness or ease, one is enjoined to take the liver of a sparrow, a swallow’s womb, a hare’s kidney, a pigeon’s heart. Dry and crush into a powder. Add equal weight of one’s own blood. Dry and mix in soup as an infallible potion. For reinvigorating purposes, an ointment composed of ash of star-lizard, civet oil, St. John’s wort oil is prepared. This is smeared on the toe of the left foot and the loins. The fat of a young buck, together with civet and ambergris, is equally efficacious.
