Re-reading Uhtred’s stories, and I’m wondering if there’s a source where I could find “the song of Aegir, god of the sea, and of Ran” (The Burning Land) or of Ravn’s chant at Ragnar’s sacrifice to Odin (The Last Kingdom).

You have got me happily immersed in Nordic and Anglo Saxon culture to a quite remarkable degree.
