Whether or not the Theology was by Aristotle, it was destined to become the key source for Neoplatonic ideas in Arabic. We see its influence over a period of many centuries, starting immediately with other versions of Greek texts produced in the ninth century. As mentioned above (§3) it was a chief influence on the Book of Causes, the Kindi circle adaptation of Proclus’ Elements of Theology. It also seems to have influenced the roughly contemporaneous version of Aristotle’s De Anima, and the treatment of the soul’s immateriality by the ninth-century Christian author Qusṭā Ibn Lūqā (Giommoni 2019).
