Gemory is described in demonological works such as the Munich Manual of Demonic Magic[note 1][1][2][3] the Liber Officiorum Spirituum[note 2][4][5] the Pseudomonarchia Daemonum,[note 3][6] the Lesser Key of Solomon,[note 4][7] the Dictionnaire Infernal,[note 3][8] as appearing in the form of a beautiful woman (though as with all Goetic demons referred to using the masculine pronouns "he" and "his") wearing a duchess's crown and riding a camel, ascribed with the power of revealing hidden treasures and answering questions about the past, present, and future.[8][1][7][4][5][6] The Munich Manual, Pseudomonarchia, Lesser Key, and Dictionnaire further give Gemory the power of procuring love from women[8][1][7][6] (although the Liber Officiorum Spirituum describes her as "a companion of the love of women, and especially of maidens"),[4][5] while the Pseudomonarchia and the Lesser Key note that the duchess's crown is (somehow) worn on Gemory's waist.[7][6]Stephen Skinner and David Rankine, in their edition of The Goetia of Dr Rudd, suggest that this was a mistranslation of the Latin cingitur which should have been translated "encircling her head".[9]
Gemory is mentioned in a manuscript labelled Fasciculus Rerum Geomanticarum.[note 1][10]
According to Rudd, Gremory is opposed by the Shemhamphorasch angel Poiel.[9]
