Idun was the beautiful goddess who in Asgard was keeper of the apples which the gods ate to preserve eternal youth. She is most generally regarded as the wife of Brage. Heimdal, the son of nine mothers, was guardian against the giants of the bridge of the gods, Bifröst. With a trumpet he summoned all the gods together at Ragnarok when he and Loke slew each other. He was the god of light. Loke though beautiful in form was like Lucifer in character and was hence called the god of destruction. By the giantess Angerboda he had three offspring, the Midgard serpent, the Fenris-wolf, and Hela, the latter becoming goddess of Hel.
