Toz Graecus was cited by more than one medieval writer and the work which we have just been describing was not the only one that then circulated under his name, although it seems to be cited by Daniel Morley in the twelfth century.[690] Albertus Magnus in his list of evil books on images in the _Speculum astronomiae_ included a work on the images of Venus,[691] another on the four mirrors of Venus, and a third on stations for the cult of Venus. This last is also alluded to by William of Auvergne, bishop of Paris, in his _De universo_, and ascribed by him to “Thot grecus.”[692] There also was once among the manuscripts of Amplonius at Erfurt a “book of Toz Grecus containing fifty chapters on the stations of the planets.”[693] Cecco d’Ascoli, the early fourteenth century astrologer, mentions together “Evax king of the Arabs and Zot grecus and Germa of Babylon.” Which reminds one of Albert’s allusion in his theological _Summa_[694] to “the teachings of that branch of necromancy” which treats of “images and rings and mirrors of Venus and seals of demons,” and is expounded in the works of Achot of Greece--who is probably our Toz Graecus, Grema of Babylon, and Hermes the Egyptian. And again in his work on minerals[695] Albert lists together as authorities on the engraving of gems with images the names of Magor Graecus, Germa of Babylon, and Hermes the Egyptian. [Sidenote: Toz the same as Thoth or Hermes Trismegistus.] Moreover, not only is the work of Toz closely associated both in the extant manuscripts and by Albertus Magnus with that of Hermes, but William of Auvergne’s spelling “Thot” shows what has perhaps already occurred to the reader, that this Toc or Toz Graecus is no other than the Greek equivalent of the Egyptian god Thoth; in other words, Hermes Trismegistus himself. I have not yet mentioned one other treatise found in a seventeenth century manuscript, and which, while very likely a later invention, shows at least that Toz remained a name to conjure with down into modern times.[696] The work is called _A commentary by Toz Graecus, philosopher of great name, upon the books of Solomon to Rehoboam concerning secrets of secrets_. A long preface tells how Solomon summed up all his vast knowledge in this book for the benefit of his son Rehoboam, and Rehoboam buried it in his tomb in an ivory casket, and Toz after its discovery wept at his inability to comprehend it, until it was revealed to him through an angel of God on condition that he explain it only to the worthy.
