 Rübezahl is the fantastic Lord of Weather of the mountains and is similar to the Wild Hunt.Unexpectedly or playfully, he sends lightning and thunder, fog, rain and snow from the mountain above, even while the sun is shining.He may take the appearance of a monk in a gray frock (like Wotan in his mantel of clouds); he holds a stringed instrument in his hand (the storm harp), and walks so heavily that the earth trembles around him.
