This catalogue contains descriptions of Persian medical manuscripts in the collection at UCLA; Persian texts in predominantly Arabic MSS are also listed, without descriptions. “Numerically, UCLA’s collection of Persian medical manuscripts ranks among the first in Western countries. In this catalogue, 135 Persian and two Arabic titles are discussed [ . . . ] Nearly the whole period during which the Persian language has been used for writing on medical subjects is covered by the collection [ . . . ] The earliest author represented is the oculist ‘Zarrindast’ of the late fifth/eleventh century, approximately 100 years after the first appearance of medical writing in Neo-Persian.” [from the Preface]
