An Animal Within an Animal

“In the middle of the flanks of women lies the womb, a female viscus, closely resembling an animal; for it is moved of itself hither and thither in the flanks, also upwards in a direct line to below the cartilage of the thorax… and in a word, it is altogether erratic… on the whole, the womb is like an animal within an animal.” – Aretaeus, physician, 2nd century AD
