In stanza 24 of Vafþrúðnismá, the god Odin (disguised as "Gagnráðr") asks the jötunn Vafþrúðnir from where the day comes, and the night and its tides.
In stanza 25, Vafþrúðnir responds: In Hávamál, the dwarf Þjóðrœrir is stated as having recited an unnamed spell "before Delling's doors": In the poem Fjölsvinnsmál, Svipdagr asks "What one of the gods has made so great the hall I behold within?"
"[6] In chapter 10 of the Prose Edda book Gylfaginning, the enthroned figure of High states that Dellingr is a god and the third husband of Nótt.
[7] However, scholar Haukur Thorgeirsson points out that the four manuscripts of Gylfaginning vary in their descriptions of the family relations between Nótt, Jörð, Dagr, and Dellingr.
Haukur details that "the oldest manuscript, U, offers a version where Jǫrð is married to Dellingr and the mother of Dagr while the other manuscripts, R, W and T, cast Nótt in the role of Dellingr's wife and Dagr's mother", and argues that "the version in U came about accidentally when the writer of U or its antecedent shortened a text similar to that in RWT.
