Iðunn and Bragi
'One of the gods is called Bragi. Though renowned for his wisdom, he is mostly known for his eloquence and his way with words. He is the most knowledgable about poetry, and because of him poetry is named brag*. From his name comes the usage whereby a person, more skilled with words than others, is called a bragr* or the foremost of men or women.
‘His wife is Iðunn. In her private wooden box she keeps the apples which the gods bite into when they begin to grow old… They all become young again, and so it will be right up to Ragnarök.’
