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.

Goose testes and the stomach of a hare, well seasoned with spices, are amatory aids.

Also: a salad made of satyrion, rocket, and celery, soaked in oil and rose vinegar.

As, in rarer cases, an anaphrodisiac, on the other hand, the powdered genitals of a mild bull are recommended, in a soup containing veal, purslain, and lettuce.

The medieval grimoires, those manuals dedicated to sorcery, also treated of philtres and amatory brews.

Take two new knives. On a Friday morning—the day that is consecrated to Aphrodite—go to a spot where you can find earthworms. Take two, join the two knives together, then cut the two heads and the two tails of the worms. Keep the bodies. On returning home, smear them with sperm: dry, and pulverize them.
