The Eighth Spirit is Barbatos. He is a Great Duke, and appeareth when the Sun is in Sagittary, with four noble Kings and their companies of great troops. He giveth understanding of the singing of Birds, and of the Voices of other creatures, such as the barking of Dogs. He breaketh the Hidden Treasures open that have been laid by the Enchantments of Magicians. This is an excellent wealth djinn for artists and musicians.
