Barbatos

One of the seventy-two demons listed in the Goetia.  He also appears in the Pseudomonarchia Daemonum of Johannes Wieus and the Discoverie of Witchcraft by Reginald Scot.  In these texts, he is identified as both a count and an earl.  In Dr. Rudd's Treatise on Angel Magic, his rank is listed as duke.  In most of these texts, he is said to rule over thirty legions of lesser spirits.  The Goetia of Dr. Rudd gives this number as three hundred.  When he manifests, Barbatos is reputed to appear with a grand retinue that includes troops and companies of infernal spirits, along with four kings.  He can teach all manner of inhuman languages, from the bharking of dogs to the songs of birds and the lowing of cattle.  He can also detect treasure that has been hidden with enchantments.  He was originally of the angelic Order of Virtues.  He appears when the sun is in Sagittarius and he can be constrained by the angel Cahetel.  He is also named in the Welsh grimoire known as the Book of Incantations.  In this text, he is again a duke who governs thirty legions.   See also Book of Incantations, Goetia, Rudd, Scot Wierus.
