General Attributes

The hydros is a water snake that causes those bitten to swell up, the cure for which is the dung of an ox.


Isidore of Seville [7th century CE] (Etymologies, Book 12, 4:22): The hydros is a water snake; its bite makes the victim swell up. The disease caused by the bite of this snake is sometimes called boa because it can be cured with ox (bos) dung.
