I wonder if he just had a broken heart. He saw his world changing and knew it was gonna be time to find some other means of employment. I think it's interesting that some of the greatest prime figures in mythology somehow die of a broken heart. What could be more tragic and romantic. Also it's a death that cannot be treated by medicine but only cured by one's own soul. This allows that it was a very personl matter going beyond the realm of mortal fixing. I believe that if he lived and died and did so in the course of events as told in the tale here. he has done so because of the repeated telling and building of the lore needed to inrich the listeners. That is good enough for a romantic non-scholar such as myself. I am thankful for either his life or non-so.
