Khosrau I
Under Khosrau I, the Academy of Gundishapur, which had been founded in the 5th century, became "the greatest intellectual center of the time", drawing students and teachers from every quarter of the known world. Nestorian Christians were received there, and brought Syriac translations of Greek works in medicine and philosophy. The medical lore of India, Persia, Syria and Greece mingled there to produce a flourishing school of therapy.
