Annarr

In Norse mythology, according to the Gylfaginning, Annarr (Old Norse "second, another") or Ónarr (Old Norse "gaping") is the second husband of Nótt (the Night) and the father of Jörð (Mother Earth).

Annarr/Ónarr is also the name of a dwarf in the catalogue of dwarfs in the Völuspá that is repeated in the Gylfaginning.

Attestations
In the pseudo-historical genealogy of Odin's ancestors in the introduction to Snorri Sturluson's Prose Edda, a certain Athra is said to be he "whom we call Annarr". What this refers to is unknown.

In the Gylfaginning Snorri writes of Nótt: "She was given to the man named Naglfari; their son was Aud. Afterward she was wedded to him that was called Annarr; Jörð ['Earth'] was their daughter." Snorri might have been using a source in which annarr 'second, another' was intended to mean Odin, for he himself had just previously written of Odin: "The earth was his daughter and his wife...".

But in the Skáldskaparmál Snorri uses the form Ónar instead, giving "daughter of Ónarr" as one of the kennings for Jörð. Snorri also cites from Hallfreðr vandræðaskáld: "In council it was determined" "That the King's friend, wise in counsel, Should wed the Land, sole daughter" "Of Ónar, greenly wooded. His grandson is the god Thor."
