Genizah fragments T-S Ar.44.4 and T-S NS 31.6

[Paul Ferguson]

'On close examination Gabriele Ferrario discovered it was in fact a collection of alchemical recipes. What makes it special, compared to many other alchemical recipes in the Genizah, is that there are not only technical instructions but they reference in quite a lot of detail books of Arabic alchemical literature – works from the Jabirian corpus.'
