In so far as I have examined the alchemical manuscripts of the later middle ages,[658] which I have not done very extensively owing to the fact that most of them consist of anonymous and spurious compositions which are probably of a later date than the period with which we are directly concerned,[659] I have hardly found as many treatises ascribed to Hermes Trismegistus as might be expected. Perhaps as many works are ascribed to Aristotle, Geber, and other famous names as to Hermes or Mercury. Thus out of some forty items in an alchemical miscellany of the fourteenth or fifteenth century[660] two are attributed to Hermes and Mercury, two to Aristotle, one to Plato, three to Geber, two to Albertus Magnus, and others to his contemporaries like Roger Bacon, Brother Elias, Bonaventura, and Arnald of Villanova. Of the two titles connected with Hermes one is simply a _Book of Hermes_; the other, _A Treatise of Mercury to his disciple Mirnesindus_. Other specimens of works ascribed to Hermes in medieval Latin manuscripts are: _The Secrets of Hermes the philosopher, inventor of metals, according to the nature of transmutation_[661] or in another manuscript, “inventor of transformation,”[662] a treatise on the fountain of youth by Trismegistus;[663] and a work on alcohol ascribed to “father Hermes.”[664] The Early English Text Society has reprinted an English translation of the Latin treatise on the fifth essence “that Hermes, the prophet and king of Egypt, after the flood of Noah, father of philosophers, had by revelation of an angel of God to him sent,” which was first published “about 1460-1476 by Fred J. Furnival.”[665] “The book of Hermogenes” is also to be accredited to Hermes Trismegistus.[666] [Sidenote: Medieval citations of Hermes]
