With this fascinating book, G. Ronald Murphy takes his readers on an extraordinary journey (of interpretation) to Scandinavia and the United Kingdom to visit the Jelling Stone in Jutland, stave churches in Norway, the round churches with their central pillar on the island of Bornholm, the burial crosses in Yorkshire, and the Ruthwell cross in southwest Scotland. What all of these artifacts have in common is that they are indebted to the interweaving of cross and tree in the North: “Their creation is an expression of northeners’ realization of the rescuing function of Christ's cross in terms of the story of the evergreen Yggdrasil” (4). In part II, the author turns to other cultural monuments, that is The Dream of the Rood, the Ruthwell Cross, and the runes carved on the cross. It is argued that the sequence of the fuãark is likely a mnemonic based on the Yggdrasill myth, influenced by Christianity. To substantiate his argument, Murphy examines and interprets the iconography of c-type bracteates from the fifth to eighth century CE, which are evidently related to the myth of Woden, the runes, and the tree. Part III treats tree-related rituals in pre-Christian and Christian times: the Yule wreath and the Christmas tree. Tree of Salvation: Yggdrasil and the Cross in the North is a highly original, insightful, and sophisticated study. The book will be much cited.
