Arabische Alchemisten II : Ǧaʿfar Alṣādiq

[Paul Ferguson]

"The last one-third of the book is in medieval Arabic. The middle one-third of the book is a translation of the medieval Arabic into modern German. The first one-third is intro and commentary in German. The medieval century in which the medieval Arabic was written is uncertain."
