He appeareth at the first show in the form of an ugly Viper, then at the command of the Magician he putteth on a Human shape with Great Teeth, and two Horns, carrying a bright and sharp Sword in his hand. He telleth all things Past, and to Come, and reconcileth Friends and Foes. He ruleth over 60 Legions of Spirits, and this is his Seal, etc.
