Idunn (“The Rejuvenating One”) is a goddess who belongs to the Aesir tribe. Idunn is the owner and dispenser of a fruit that imparts immortality J her presence was indispensable in Asgard. Today, her fruit of immortality is considered to be an apple, but this wasn’t necessarily the case in heathen times. The Old Norse word for ‘apple’ was “epli”, which used to denote any fruit or nut, and “apples” in the modern English sense didn’t arrive in Scandinavia until late in the Middle Ages. Her energy is invoked for rejuvenation, youth and regeneration.
