Nanna, in Norse mythology, a goddess and the wife of the beautiful god Balder. She was the mother of Forseti, the god of justice. Her name means "mother of the brave." Little is known of Nanna except in her connection with Balder. The 'Prose (or Younger) Edda' mentions that she was the daughter of Nep, who was probably a giant. After Balder was killed through the trickery of the fire god Loki, all the gods and many other beings gathered for a great funeral rite. Nanna was so stricken with grief that she collapsed during the funeral and died of anguish. She was immediately carried out to Balder's pyre on the funeral ship and laid next to her husband, and both bodies were burned together as the ship was cast out to sea. All the gods were so grief-stricken by the loss of Balder that the god Hermod traveled to the underworld to try to negotiate with the goddess Hel for Balder's return to the heavenly realm of Asgard. While in Hel, he visited with the ghosts of Balder and Nanna there. Nanna--still a thoughtful, gracious lady even in Hel--gave Hermod a linen robe for Frigg, the wife of the principal god, Odin, along with other gifts to bring back to the living.
