The scholars who have studied hitherto the Greek magical papyri, such as Parthey, Wessely, Dieterich, and others, have either concentrated their attention upon the Greek forms contained in these documents, or have tried to find a connecting link between these books, notably between the weird notions contained therein and Greek and Egyptian parallels. Greek mysteries have been adduced in order to explain some of the curious notions prevailing in these papyri. Egypt had to serve for explaining the origin of some of the mystical names or angels mentioned therein. From time to time allusion has been made to so-called Cabalistic parallels, without any clear proof being furnished as to the dependence of one upon the other. But one branch of literature has been entirely neglected, which ought to have attracted attention in the first place, namely, the apocryphal and pseudo-epigraphic literature, which is the only truly contemporary literature. Similarity in tendency, claim of great antiquity, and open or covert allusions to heavenly mysteries show close affinities of no mean order. The authors in one case would be the very persons to avail themselves of the information furnished by the other. The world in which the writers of the apocryphal literature move has not been very much different from that in which the writers and speculators in this mystical lore, preserved, in the papyri, have lived. And one would have thought that the material offered by the apocryphal literature would have been the first to be utilized for the elucidation of some of the problems connected with these magical papyri.
