Sometimes I have an overactive imagination when i read the Poetic Edda. Reading this verse, it sounds like Odin (calling himself Harbarth in this poem) visited England! (or the Isle that would later become England) "And dwelt in the Isle that is Algron called". The word Algron means the 'All Green' in a similar way to how our England is called 'our green and pleasant land' and similar to Albion. The pre Roman Celtic / British peoples did have legends of Giants roaming the land and that we descended from giants.........
I wonder if this is how Joseph Smith felt when he said that jesus was in Missouri lol. (Though obviously this is based on real Gods)
Harbarth spake: 16. "Five full winters | with Fjolvar was I, And dwelt in the isle | that is Algrön called; There could we fight, | and fell the slain, Much could we seek, | and maids could master."
(PS this was just the humorous ponderings of my mind. Don't take it too seriously)
