Gaap

A demon named in both the Pseudomonarchia Daemonum Johannes Wierus and Scot's Discoverie of Witchcraft.   Gaap is also one of the traditional seventy-two demons of the Goetia.  He is described as both a president and a prince, although there is evidence in the Goetia of Dr. Rudd that suggests his real title should be king.  He has a total of sixty-six legions under his command.  In Heaven, he reputedly belonged to the angelic Order of Powers, sometimes also called the Order of Potestates.  He is said to appear in a sign in the meridian, but the exact sign is left unspecified in the Pseudomonarchia.  In the Goetia, he is said to appear when the sun is in certain southern signs (it doesn't say which signs).   When he assumes human form, he appears as a doctor, and he is said to be an excellent "doctor" of women, causing them to burn with love for men.  Gaap is also credited with being as mighty a demon as the infernal king Bileth, and he acts as a guide to the four principal kings.  In addition to his ability to make women lust after men, he is credited with a number of powers.  He is said to steal familiar spirits from other conjurors.  He teaches philosophy and the liberal sciences, and he answers on matters concerning the past, present, and future.  He can also inspire love and hatred among people, and has the power to consecrate things under the dominion of the infernal king Amaimon, although the precise utility of this power is unclear.  Alternate versions of his name include Tap and Goap.  In the Goetia of Dr. Rudd, Gaap is said to belong to Amaimon, thus allying him with the court of the east.  He can be constrained by the angel Jehujah.  In the Binsfeld hierarchy of demonsconnected to the Seven Deadly Sins, Gaap is equateed with Satan.  He is also named in the Welsh Book of Incantations, where it affirms that he appears when the sun is in one of the southern signs.  He holds the rank of prince and governs sixty-six legions.  Later in the same manuscript, his rank is given as president.  He teaches philosophy and science, transports people from place to place, and can cause love or hatred.  See also AMAIMON, BILETH, BOOK OF INVANTATIONS, GOETIA, RUDD, SATAN, SCOT, WIERUS.
