This study challenges the conventional image of the tenth-century Sufi mystic Al-Husayn Ibn Man?ur al-?allag (d. 929) as an anti-philosophical mystic. Unlike the predominantly theological or text-historical studies which constitute much of the scholarly literature on ?allag, this study is completely philosophical in nature, placing ?allag within the tradition of Graeco-Arabic philosophy and emphasizing, in a positive light, his continuity with the pagan Neoplatonism of Plotinus and Proclus.
