In Norse mythology, according to the Gylfaginning, Annar (Old Norse Annarr 'second, another') is the father of Jörð (Mother Earth) by Nótt (the Night). The form Ónar (Old Norse Ónarr 'gaping') is found as a variant. Annar/Ónar is also the name of a dwarf in the catalogue of dwarfs in the Völuspá that is repeated in the Gylfaginning.
