KHIONE (or Chione) was one of the nymphs and the consort of Boreas, god of the chill north-wind. She was probably also the goddess of snow (khiôn), as her name suggests.

Khione is connected with Oreithyia ("Mountain Gale") and another Khione ("Snow"), who are elsewhere described as the wife and daughter of the god.

Aelian, On Animals 11. 1 (trans. Scholfield) (Greek natural history C2nd A.D.) :
"The race of the Hyperboreoi and the honours there paid to Apollon are sung of by poets . . . This god has as [Hyperborean] priests the sons of Boreas (North Wind) and Khione (Snow), three in number, brothers by birth, and six cubits in height."
