Rune Kennings are associated with ancient Icelandic poetry but can also be found in such tales as the famous Anglo-Saxon poem of Beowulf. But they certainly are most prevalent with Runic text of Iceland.
I have studied them for years now and still continue to explore deeper into them even to the point of creating my own.
Two books which you can find a great list of Rune Kennings are Sorcerer’s Screed: The Icelandic Book of Magic Spells and Icelandic Magic: Practical Secrets of the Northern Grimoires.
