[658] Berthelot is a poor guide in any such matter since his pretentious volumes on medieval alchemy are based on the study of a comparatively small number of MSS at Paris. He made little or no use of the Sloane collection in the British Museum which is very rich in alchemical MSS, a subject in which Sir Hans Sloane was apparently much interested, or of the Ashmolean collection at Oxford, although Elias Ashmole edited the _Theatrum Chemicum Britannicum_, 1652, “containing several poetical pieces of our famous English philosophers who have written the hermetic mysteries in their own ancient language,”--a work in which Ashmole himself is called _Mercuriophilus Anglicus_. [659] The two earliest MSS used by Berthelot for medieval Latin alchemy were BN 6514 and 7156 of the late 13th or early 14th century. In an earlier chapter we have mentioned Berlin 956 of the 12th century, fol. 21, “Hic incipit alchamia,” and probably a fairly long list could be made of alchemical MSS of the 13th century, like Digby 162 mentioned in a previous note to this chapter. However, as a rule the numerous alchemical collections in the Sloane MSS--a majority of the MSS numbered from about 3600 to about 3900 are in whole or part concerned with alchemy, as well as a number of earlier numbers--are not earlier than the 14th and 15th centuries, and many are subsequent to the invention of printing.
