 Ibn al-Imam (IB-coll-fakhry: 177–178) produced the first list of Avempace’s writings, which was followed by Ibn Abi Usaybi‛a in his bio-bibliography (mentioned above, 1886, 2001). A scholarly account was first made by the late Jamal ad-Din al-‛Alawi (1983) who not only described manuscripts and printings, but also tried to determine which works ascribed to Avempace are authentic, as well as to establish the chronology of his writings and, on this basis, to draw a developmental account of his thought.
