"The leaven of the ancients : Suhrawardī and the heritage of the Greeks" by John Walbridge (2000)

"The twelfth-century Persian philosopher Suhrawardi was the key figure in the transition of Islamic philosophy from the neo-Aristotelianism of Avicenna to the mystically oriented Islamic philosophy of later centuries. Suhrawardi's "Illuminationist" philosophy was a vigorous reassertion of Neoplatonism at a time when Sufism was becoming a major presence in Islamic thought and society."--BOOK JACKET.
