ER Eddison influenced James Blish's After Such Knowledge Trilogy. See here. He also wrote:
"The Icelandic sagas...have another quality which they share only with a few of the great literary masterpieces of the world: the quality of vivid, unstaled and undauntable life."
-quoted in Poul Anderson, Hrolf Kraki's Saga (New York, 1973), p. i.
I have argued that "Anderson celebrates life." See here.
From Eddison's statement that the sagas share the quality of vivid life only with a few great literary masterpieces and from my argument that Anderson celebrates life, it follows that Anderson's works are among those few great literary masterpieces! Of course, I do not need to deduce a conclusion from premises written by Eddison and myself. I experience the greatness of Anderson's literary achievements by rereading and appreciating his works - and it is appropriate that those works include the retelling of Hrolf Kraki's Saga.
