The medieval Solomonic grimoires are, in fact, a sub-set of a larger literary genre - the folkloric ' receipt-book.' ( The word ' receipt', used in this sense, is an archaic form of the word 'recipe.') A receipt-book was a hand-written journal of family and local folklore, passed down from generation to generation. As with The Key of Solomon, de-Laurence published a pirated American edition. In 1903 Crowley and Mathers had a falling out, and Crowley published Mathers's work in 1904. For whatever reason, the Lemegeton was not published and existed only in a manuscript version, which Mathers lent to Aleister Crowley. It seems to date from the sixteenth century. Theurgia-Goetia is part of Lesser Key of Solomon, (1916) and lists a large number of spirit entities and gives instructions for summoning them. Theurgia-Goetia: Theurgy literally means High Magic, the tradition which deals with the methods of working with good spirits, especially the conjuration of 32 Ariel Spirits and their servants, who govern the points of the compass.
