Hyrieus was the king and founder of Hyria, in Boeotia. In view of his unique method of fathering
Orion (by urinating on a bull hide) it is tempting to derive his name from hyo, 'to wet', 'water', 'rain' (compare the Hyades), but this overlooks the V. However, this letter may have appeared by association with the name of Orion (or with ouron, Wine').
