- “The Seed of Yggdrasill – Deciphering the Hidden Messages in Old Norse Myths” was first published by Whyte Tracks Inc. in 2013-2019. It is a work about the use of metaphors in the mythical Edda poetry and how to decipher them in order to understand the meanings that the poets were trying to convey. In this work, Kvilhaug takes the consistent use of meaningful heiti (nicknames) and kenningar (metaphors) in Old Norse poetry seriously and considers the mythical poems in the light of three major influences she believes can be detected in these poems; 1) the Medieval tradition of Integumenta (an understanding of pagan myths as basically allegorical, parables about the human condition in a greater cosmos) and 2) the myths of Classical Mystery religions (in which each Classical myth is considered a parable about the human soul´s path towards union with the divine) and 3) the ancient connection between the Norse traditions and the Indo-European ancestors of the Vedic (Indian) and Avestan (Iranian) traditions of a philosophical and metaphysical approach to the universe and the meaning of life expressed through the allegories of myth.
