writers were usually also exponents of logic and commentators on Aristotle as well as Galen.
The Khalif al-Mansur was the patron who did most to attract the Nestorian physicians to the city of Baghdad which he had founded, and he was also a prince who did much to encourage those who set themselves to prepare Arabic translations of Greek, Syriac, and Persian works. Still more important was the patronage given by the Khalif al-Ma'mun who in A.H. 217 (= A.D. 832) founded a school at Baghdad, suggested no doubt by the Nestorians and Zoroastrian schools already existing, and this he called the Bayt al-Hikma or "House of Wisdom," and this he placed under the guidance of Yahya b. Masawaih (d. A.H. 243 = A.D. 857), who was an author both in Syriac and Arabic, and learned also in the use of Greek. His medical treatise on "Fevers" was long in repute and was afterwards translated into Latin and into Hebrew.
The most important work of the academy however was done by Yahya's pupils and successors, especially Abu Zayd Hunayn b. Ishaq al-Ibadi (d. 263 A.H. = A.D. 876), the Nestorian physician to whom we have already referred as translating into Syriac the chief medical authorities as well as parts of Aristotle's Organon. After studying at Baghdad under Yahya he visited Alexandria and returned, not only with the training given at what was then the first medical school, but with a good knowledge of Greek which he employed in making translations in Syriac and Arabic.
