In the Norse mythology "the god of thunder; the thunder was his wrath, the gathering of the black clouds is the drawing down of Thor's angry brows; the fire-bolt bursting out of heaven is the all-rending hammer flung from the hand of Thor; he urges his loud chariot over the mountain tops—that is the peal; wrathful he 'blows in his beard'—that is the rustling of the storm-blast before the thunder begin"; he is the strongest of the gods, the helper of both gods and men, and the mortal foe of the chaotic powers.
