Alchemical manuscripts in the British Library

Sloane 1-1000

Here is a listing of alchemical manuscripts extracted from the 19th century handwritten catalogue of the Sloane collection, and the 18th century printed catalogues of the other collections, Harley etc. These descriptions are inadequate and in some places erroneous, but in the absence of a modern printed catalogue this listing will allow researchers to find items of interest to them. The list is incomplete in some places, and I will endeavour to update this when time permits.

MS. Sloane 363.
Vellum. Quarto. 60 folios. 15th Century.
A treatise upon alchymy, which appears to be entitled, 'The consideration of quynte essence of all thinges that mowe be changid from oon kynde to an other'; it consists of three books, the first of which is named, 'The boke of the lykenesse and simulacion of philosophie'; the second, 'The boke of generall remedies yn curyng and heelyng', and the third, which is very imperfect at the end, 'of the werkes of alkymye'.
In the second book, at f.50b, is contained the treatise of the seven herbs found be Alexander Africus in the tomb of the Kiranidae.
In the prologue to the third book the translator tells us 'this labor and this translacion at the instance and prayer of a poure creature, and to the helping of man, I, Mahuedis, beyng at greete unease in prisone, have thees foreseide bokes hidre to itake a hande, and so I shal fynyshe hit, to God be the laude and preisyng.' It appears probable from the allusion to St. Francis at f.33b that the compiler was a Franciscan Friar. The prologue to the second book ends with 'Amen qd. Rogier Bacon', and a modern hand has written, 'St. Dunstan and part of R. Bacon', at the commencement of the treatise, but upon what ground it is ascribed to these authorities does not appear.
