Which horse pulls the chariot of Night (Nótt)?

The horse that pulls the chariot of Night, Nótt, is Hrímfaxi.

Hrímfaxi appears in the Norse mythological pairing with Skinfaxi. Hrímfaxi serves Nótt, the personification of night, while Skinfaxi serves Dagr, the personification of day. Their names reflect the contrast between darkness and light: Hrímfaxi means “frost mane,” while Skinfaxi means “shining mane.”

As Hrímfaxi travels through the sky with Nótt, froth falling from the horse’s bit is said to become the dew that settles on the earth. This image explains a natural phenomenon through the movement of a divine chariot, a pattern common in mythic descriptions of the sun, moon, day, and night.

The main mix-up is with Árvakr and Alsviðr, the pair associated with the chariot of the sun. Skinfaxi is another frequent confusion because he is also a cosmic horse, but his driver is Dagr rather than Nótt.
