The Bonnacon’s range extends from Scythia in the east to Bulgaria, Macedonia, and Germany in the West. It would be a fine prize for hunters were it not for its remarkable flatulent defenses.

A bonnacon looks like a bull, but is squatter, with reddish fur shading to black, a short tail, and the shaggy mane of a horse. Its horns curl inwardly towards the head, making them of no use in self-defense.

When attacked, the bonnacon voids the contents of its intestines over an area of 3 acres (Aristotle gives a more conservative estimate of 4 fathoms). The noxious, acrid dung ignites and burns anything it touches, leaving a trail of flame in its wake.

The European bison (Bison bonasus) is generally believed to be the basis of the bonnacon.
