Istio
From BiblePortal Wikipedia
Istio [1]
in Teutonic mythology, was one of the three sons of Mannus, and the father of one of the three races of the Germans. Ithun, in Norse mythology, is held imprisoned under the ash-tree Ygdrasil. Probably this Ithun is identical with Iduna, who guards the rejuvenating apples of the gods.
