This book offers an annotated English translation of one of the earliest dispensatories ever written in the Arabic language, viz. the small version of the Aqrabadin composed by the Nestorian physician Sabur ibn Sahl (d. 869 CE). The translation is based on the edition of the Arabic text as published in volume 16 of the IPTS series, which in turn is based on the oldest handwritten witness of Arabic pharmacy known so far. The translation is framed by a detailed introductory study of the subject, and by various glossaries which make this important source text accessible from both the Arabic and the English side. The book thus marks the first serious attempt at fully translating an early Arabic dispensatory into a modern Western language.
