Sheikh Adi ibn Musafir is the historical founder-saint at the heart of Yezidism. Born in the 1070s at Bait Far near Baalbek in the Beqaa valley, of a family reputed to descend from the Umayyads, he studied Sufism in Baghdad before withdrawing in the early twelfth century to the remote valley of Lalish north of Mosul. There he established the ʿAdawiyya order and gathered the community of followers whose fusion of his teaching with older local religious traditions produced the Yezidi faith. He died at Lalish about 1162, and his domed tomb remains the central Yezidi shrine and the focus of pilgrimage. In Yezidi sacred poetry the historical ascetic is wholly transfigured into a divine being: he is the second of the three hypostases of the one God, alongside Tawûsî Melek and Sultan Ezid, and is repeatedly identified as an earthly manifestation of the Peacock Angel himself.
