This is the mighty Aslan slumbering. I've always loved C. S. Lewis stories of Aslan, the "Great Lion." Aslan is a mysterious talking lion, King of the Beasts, beloved guide to the human children who visit the Land of Narnia. Despite his gentle, wise and loving nature, Aslan is "not a tame lion." He is powerful and can be dangerous to those who plot evil against the ones He loves.
