 Aristotle. Abu Bishr Matta translated into Arabic the Syriac version of the Posterior Analytics made by Ishaq ibn  Hunayn[94]  and the Syriac translation of the  Poetics.[95]  Even though he did not know Greek, the ancient sources mention also a translation by him into Syriac (hence, from Greek) of the Sophistici  Elenchi.[96]  The sources mention also a partial translation of the De Caelo by  him,[97]  as well as a translation of the De Generatione et  corruptione.[98]  Abu Bishr Matta also translated the De Sensu et  sensato[99]  and Book Lambda of the Metaphysics, together with Alexander of Aphrodisias’  commentary.[100]  To his pupil Yahya ibn ʿAdi—who was also a Christian theologian and the author of philosophical  treatises[101]—is  attributed the Arabic version of the Syriac translation of the Topics made in the previous century by Ishaq ibn  Hunayn.[102]  Yahya ibn ʿAdi is credited also with the Arabic translation of the Sophistici Elenchi from the Syriac version of Theophilus of  Edessa,[103]  as well as with that of the  Poetics.[104]  One of the Christian pupils of Yahya ibn ʿAdi, Abu ʿAli ibn al-Samh, was the “editor” of the ancient translation of the Rhetoric: it is this text which has come down to  us.[105]  Abu ʿAli ibn Zurʿa, another Christian of this milieu, might have translated an Alexandrian compendium of the Nicomachean Ethics known as Ikhtisar al-Iskandaraniyyin (Summa Alexandrinorum) (Dunlop 1982; Zonta 2003, 197). The 10th century Baghdad Aristotelian Abu l-Faraj ibn  al-Tayyib[106]  translated the pseudo-Aristotelian De Virtutibus et vitiis and Divisiones (ed. Kellermann-Rost 1965; see also Ferrari 2006, 30), and might be also the translator of the pseudo-Aristotelian Economics (Zonta 2003, 549).
