Dellingr

In Norse mythology, Dellingr (Old Norse "the shining one" or "day-bringer") is an Áss god who is the father of Dagr, the personification of day. Dellingr is primarily known from the Völsunga saga and Gylfaginning, a section of the Prose Edda written by Snorri Sturluson.

According to Gylfaginning, Dellingr is married to Nótt (Night). Their union produces Dagr, whose beauty and radiance inherited from his father are said to illuminate the earth. This family provides an explanation for the succession of night and day in Norse cosmology.

The exact role and characteristics of Dellingr beyond his parentage are not extensively detailed in surviving Norse texts. He appears to exist primarily to provide a father figure for Dagr and an origin for the concept of day itself. The etymology of his name further reinforces his association with light and the dawn. He is not a central figure in surviving narratives, but his existence is integral to the Norse understanding of the diurnal cycle.
