The Demon Gaap is a Fallen Angel and 33rd of the 72 Spirits of Solomon. Once a member of the angelic order of powers, Gaap is a president and mighty prince in Hell, ruling 66 Legions of Demons. He appears when the Sun is in the southern signs, as a human with huge bat’s wings and preceded by four powerful kings. Gaap teaches liberal sciences and philosophy; excites love and hatred; makes men insensible; gives true answers about the past, present, and future; and takes familiars away from magicians.
Upon command, he will move people quickly from place to place. Gaap gives instruction in the consecration of things that belong to the divination of his master, Amaymon.
From “Demonologia” ( August 2003 )
This Demon is also sometimes known as Tap. The text of the Lemegeton reads:
“he is a President; and a mighty Prince; he appeareth when the Sun is in some of theSouthern Signs in a humane shape; Going before him 4 Great and Mighty Kings knowing Philosophy; and all the Liberal Sciences; he can cause love or hatred, and make men insensible; he cann teach you how to Consecrate those things that belong to the Dominion of Amaymon his King, and cann deliver familiars out of the Custidy of other Magicians; and men most speddly an Kingdom to Another at the will and pleasure of the Exorcist; he ruleth 66 Legions of Spirits; he was of the Order of Potentates;” (Sloane 2731).
Reginald Scot has some curious lore to record in connection with this Demon. He states that Gaap is equal in might to Bileth, and writes of the latter spirit:
“there were certaine necromancers that offered sacrifices and burnt offerings unto him; and to call him up, they exercised an art, saieng that Salomon the wise made it. Which is false: for it was rather Cham, the sonne of Noah, who after the floud began first to invocate wicked spirits. He invocated Bileth, and made an art in his name, and a booke which is knowne to manie mathematicians. There were burnt offerings and sacrifices made, and gifts given, and much wickednes wrought by the exorcists, whomingled there with all the holie names of God, the which in that art are everie where expressed. Marie there is an epistle of those names written by Saloman, as also write Helias, Hierosolymitanus and Helisaeus. It is to be noted, that if anie exorcist have the art of Bileth, and cannot make him stand before him, nor see him, I may not bewaie you and declare the meanes to containe him, bicause it is abhomination, and for that I have learned nothing from Salomon of his dignitie and office.”
What the abominations used to command Bileth may be, Scot does not divulge. They may have involved the spilling of human blood. Bileth is evidently the same as the Demon Beleth, also known as Bileth or Bilet. Scot's text is confusing, and it is difficult to know with certainty at any given point whether he is writing about Gaap or Bileth,but I believe Bileth to be intended in the section quoted above. Gaap and Bileth are two of the four chief Demons that rule over the 72 commanded by Solomon into the vessel of brass. The other two rulers are Belial and Asmoday.
Collin de Plancy has caused Gaap to be illustrated as a winged giant with horns and a tail, who carries a man through the air on his shoulders.
From “The Goetia: The Lesser Key of Solomon the King” (1904) Written by S.L. MacGregor Mathers
GAAP. – The Thirty-third Spirit is Gaap.
He is a Great President and a Mighty Prince. He appeareth when the Sun is in some of the Southern Signs, in a Human Shape, going before Four Greatand Mighty Kings, as if lie were a Guide to conduct them along on their way. His Office is to make men Insensible or Ignorant; as also in Philosophy tomake them Knowing, and in all the Liberal Sciences. He can cause Love or Hatred, also he can teach thee to consecrate those things that belong tothe Dominion of AMAYMON his King. He can deliver Familiars out of the Custody of other Magicians, and answereth truly and perfectly of things Past, Present, and to Come. He can carry and re-carry men very speedily from one Kingdom to another, at the Will and Pleasure of the Exorcist.
He ruleth over 66 Legions of Spirits, and he was of the Order of Potentates. His Seal is this to be made and to be worn as aforesaid, etc.
From the “Pseudomonarchia Daemonum” ( 1583 )written by Johann Weyer (Johann Wier)
Gaap, alias Tap, a great president and a prince, he appeareth in a meridionall signe, and when he taketh humane shape [Clm 849 reads: He appears in the form of a doctor when he takes on a human form. He is the most excellent doctor of women, and he makes them burn with love for men.] he is the guide of the foure principall kings, as mightie as Bileth. There were certeine necromancers that offered sacrifices and burnt offerings unto him; and to call him up, they exercised an art, saieng that Salomon the wise made it. Which is false: for it was rather Cham, the sonne of Noah, who after the floud began first to invocate wicked spirits. He invocated Bileth, and made an art in his name, and a booke which is knowne to manie mathematicians. There were burnt offerings and sacrifices made, and gifts given, and much wickednes wrought by the exorcists, who mingled therewithall the holie names of God, the which in that art are everie where expressed. Marie [Certainly] there is an epistle of those names written by Salomon, as also write Helias Hierosolymitanus and Helisæus. It is to be noted, that if anie exorcist have the art of Bileth, and cannot make him stand before him, nor see him, I may not bewraie how and declare the meanes to conteine him, bicause it is abhomination, and for that I have learned nothing from Salomon of his dignitie and office. But yet I will not hide this; to wit, that he maketh a man woonderfull in philosophie and all the liberall sciences: he maketh love, hatred, insensibilitie, invisibilitie, consecration, and consecration of those things that are belonging unto the domination of Amaymon, and delivereth familiars out of the possession of other conjurors, answering truly and perfectly of things present, past, and to come, and transferreth men most speedilie into other nations, he ruleth sixtie six legions, and was of the order of potestats.
Original Text: Gaap, alias Tap, Præses magnus and Princeps: in signo Meridiei apparet: sed quum humanam assumit faciem [Clm 849, fol 66r: Apparet in signo medici cum suscipit figuram humanam; [est] doctor opti[m]us mulierum, et facit ardere in amorem virorum], ductor est præcipuorum quatuor regum, tam potens ut Byleth. Extiterunt autem quidam necromantici, qui huic libamina and holocausta obtulere, and ut eundem evocarent, artem exercuere, dicentes sapientissimum Salomonem eam composuisse, quod falsum est: imo fuit Cham filius Noë, qui primus post diluvium cœpit malignos invocare spiritus, invocavit autem Byleth, and composuit artem in suo nomine, and librum, qui multis mathematicis est cognitus. Fiebant autem holocausta, libamina, munera, and multa nefaria, quæ operabantur exorcistæ admistis sanctissimis Dei nominibus, quæ in eadem arte sparsim exprimuntur. Epistola vero de iis nominibus est conscripta à Salomone, uti and scribunt Helias Hierosolymitanus and Heliseus. Notandum, si aliquis exorcista habuerit artem Beleth, nec ipsum coram se sistere possit aut videre, nisi per artem: Quomodo autem eundem continere oporteat, non est explicandum, quum sit nefandum, and nihil à Salomone de ejus dignitate and officio didicerim, hoc tamen non silebo, ipsum reddere hominem admirabilem in philosophia and artibus omnibus liberalibus. Facit ad amorem, odium, invisibilitatem and consecrationem eorum quæ sunt de dominatione Amaymonis: Et de potestate alterius exorcistæ tradit familiares, and vera perfecte responsa de præsentibus, præteritis and futuris. Velocissimo transcursu in varias regiones traducit hominem. Sexagintasex præest legionibus, and fuit de Potestatum ordine.
From the “Dictionnaire Infernal” (edition of 1863 ) Written by Jacques Auguste Simon Collin de Plancy
Tap/Gaap is a high president and prince of hell, commanding 4 of the principal kings and 60 legions, and as powerful as Byleth. He also has an empire over thoseDemonsAmaymon commands. He appears in human form at noon, and is said to intensify the passions of love and hatred, and can transport men to different countries. Earlier necromancers invoked Tap by spells composed by King Solomon, but that is not true, as it was Noah’s son, Cham, who first began evoking evil spirits. The necromancers also offered him libations and holocausts. Tap was made to serve Byleth by composing a book of mathematics. If the exorcist knows of the art of Byleth, Gaap will not cooperate. Another book attributed to the prophets Eli and Elijah states that Gaap can be conjured by virtue of the saints’ names of God listed in the Key of Solomon.
Original Text : Tap ou Gaap, grand président et grand princeaux enfers. Il se montre à midi lorsqu'il prendla forme humaine. Il commande à quatre desprincipaux rois de l'empire infernal. Il est aussipuissant que Byleth. Il y eut autrefois des nécromanciensqui lui offrirent des libations et desholocaustes ; ils l'évoquaient au moyen d'artificesmagiques qu'ils disaient composés par le tressageroi Salomon ; ce qui est faux, car ce fut Cham, fils de Noé; qui le premier commença àévoquer les esprits malins. Il se fit servir parByleth el composa un art en son nom, et unlivre qui est apprécié de beaucoup de mathématiciens.
On cite un autre livre attribué aux prophètesÉlie et Elisée, par lequel on conjure Gaap en vertu des saints noms de Dieu renfermés dansles Clavicules de Salomon.Si quelque exorciste connaît l'art de Byleth,Gaap ou Tap ne pourra supporter la présencedudit exorciste. Gaap ou Tap excite à l'amour, àla haine. Il a l'empire sur les démons soumis àla puissance d'Amaymon. Il transporte trèspromplementles hommes dans les différentescontrées qu'ils veulent parcourir; Il commandeà soixante légions.
