كتاب جالينوس في ايام البحران

This book presents the first edition, translation, and study of Hunayn ibn Ishaq's Arabic translation of the Galenic treatise De diebus decretoriis (kitab ayyam al-buhran 'Concerning the Critical Days'). It makes available this key text on prognosis in medicine, and at the same time throws new light on the activities of perhaps the most important translator in 9th-century Baghdad.
