In Norse mythology, Dagr (Old Norse “day"[1]) is day personified. This personification appears in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In both sources, Dagr is stated to be the son of the god Dellingr and is associated with the bright-maned horse Skinfaxi, who “draw[s] day to mankind".
This is the female version of the character.
