Abstract
In this study, we want to show, through the analysis of a Christian author of the 10th. century, how commentaries on the works of Aristotle were continuously made, from the Greek commentators until Averroes. Taking as an example some texts of the Metaphysics, we can see that, even without direct contact with the original Greek version, several translations, both from the Greek and the Syriac, were compared by the author. In those cases, it was not only a translation, but also a work of commentary on the text of Aristotle. KEY WORDS – Aristotle. Metaphysics. Islamic philosophy. Translations into Arabic. Commentaries
