In the Islamic world, the writing of biographical reference works has a very long tradition. In the field of philosophy and other rational sciences such as medicine, one could, for example, mention IsḥÄq b. Ḥunaynâs (d. 298/910) TaʾrÄ«kh al-aá¹ibbÄʾ wal-ḥukamÄʾ or Ibn AbÄ« Uá¹£aybiÊ¿aâs (d. ca 668/1270) Ê¿UyÅ«n al-anbÄʾ fÄ« taʾrÄ«kh al-aá¹ibbÄʾ. The present two-volume biographical dictionary of philosophers and physicians of all times thus continues a centuries-old tradition. Its author, Quá¹b al-DÄ«n IshkawarÄ« LÄhijÄ« (d. ca. 1088-95/1677-78), was a student of the great Safavi thinker and founder of the School of Isfahan in philosophy, MÄ«r DÄmÄd (d. 1041/1631). This is also obvious from his spiritually-orientated, inclusive understanding of the various actors and episodes in the history of philosophy. Written in classical Arabic, at times sprinkled with his native Persian, it distinguishes itself from earlier dictionaries in that it also contains many of the authorâs own philosophical opinions. 2 vols; volume 2.
