Aelian’s On the Nature of Animals
A toad can kill just by belching, and the lust of the octopus is blamed for its short lifespan. To produce a mule, the horse owner must give the mare a bad haircut to shame her into having sex with a donkey. The hedgehog is considered a spiteful animal because it urinates on itself when caught, unlike the lynx, who hides its urine until it forms a gem stone.
Such are a few of the many nuggets of animal lore recorded in Aelian’s On the Nature of Animals, a translation of De Natura Animalium by the third century Roman writer Claudius Aelianus, better know as Aelian.
