"The creature was to have stood no more than 12 inches (300 mm) tall, and did the work usually associated with a golem. However, after a short time, the homunculus turned on its creator and ran away. The recipe consisted of a bag of bones, semen, skin fragments and hair from any animal, of which the chimeric homunculus would be a hybrid. This was to be laid in the ground surrounded by horse manure for forty days, at which point the embryo would form." (wikipédia)
