Did I believe her theory about Loki and Ragnarok? Of course not! Oh, I had no objection to calling Armageddon by the name ‘Ragnarok’. Jesus or Joshua or Jesu; Mary or Miriam or Maryam or Maria, Jehovah or Yahweh — any verbal symbol will do as long as speaker and listener agree on meaning. But Loki? Ask me to believe that a mythical demigod of an ignorant, barbarian race has wrought changes in the whole universe? Now, really!
