Missed that you are perusing a "poetic edda"; A new book, just out, is of the greatest interest, "Song of the Viking". Details the socio-political impact of Icelandic sagas by Snorri Sturlsen from which Tolkien borrowed almost exclusively and completely to create his immortal trilogy. King, later St. OLaf, kept three EDDA poets at hand to record his 'heroic' passing, sword in hand. Unfortunately the shieldwall was thin that day, and Olaf and the poets died together----combat reporting, then as now, is a hazardous profession, no doubt they wassail in Valhalla!
