 In this area, Avicenna’s work reflects in complex ways the influence not only of al-Fārābī but also of the Greek commentary tradition, especially Themistius and Philoponus, whose exegetical work on the Posterior Analytics, now lost in Arabic, was available to Avicenna. This becomes especially evident through implicit or explicit references to the commentators (mufassirūn) and their commentaries (tafāsīr, šurūḥ) disseminated in his own Kitāb al-Burhān (Eichner 2010, Strobino 2012, forthcoming).
