Nótt means Night. She was the goddess of the night. Nótt married three times. Her third husband was Delling. Delling was one of the Aesir and he was often considered the personified dawn.
Nótt and Delling had a son. His name was Dagr (Day). He was extremely handsome. Dagr was as light as his mother was dark. Odin put Nótt and Dagr in the sky. They each received a horse and chariot. They travelled continuously around the world. Nótt rode first and was followed by her son Dagr. Nótt was driving ahead with her horse Hrimfaxi. And behind her was Dagr driving his horse Skinfaxi.
