On the revival of Moslem orthodoxy he fell upon evil days, was persecuted as a free-thinker, and the saying is attributed to him--"Sit anima mea cum philosophic." Arabian medicine had certain very definite characteristics: the basis was Greek, derived from translations of the works of Hippocrates and Galen.

No contributions were made to anatomy, as dissections were prohibited, nor to physiology, and the pathology was practically that of Galen.

Certain new and important diseases were described; a number of new and active remedies were introduced, chiefly from the vegetable kingdom.

The Arabian hospitals were well organized and were deservedly famous.

No such hospital exists today in Cairo as that which was built by al-Mansur Gilafun in 1283.
