 Nótt's third marriage was to the god Dellingr and this resulted in their son Dagr, the personified day (although some manuscript variations list Jörð as Dellingr's wife and Dagr's mother instead).As a proper noun, the word "nótt" appears throughout Old Norse literature.In stanza 24 of the poem "Vafþrúðnismál", the god Odin (disguised as "Gagnráðr") asks the jötunn Vafþrúðnir from where the day comes, and the night and its tides.
