Skinfaxi and Hrímfaxi

In Norse mythology, Skinfaxi (Old Norse: ) and Hrímfaxi are the horses of  Dagr (day) and Nótt (night). The names Skinfaxi and Hrímfaxi mean "shining mane" and "frost mane", respectively. Skinfaxi pulls Dagr's chariot across the sky every day and his mane lights up the sky and earth below. Similarly, "froth" is believed to fall from Hrímfaxi's bit to the earth and become dew.
