 Themistius. Themistius’ paraphrasis of the  Physics[115]  was known in the circle of Abu Bishr Matta (Endress 1977, 35) and some notes which trace back to it are reproduced in the Leiden manuscript mentioned above, which contains the text of the Physics as it was studied in the Baghdad  school.[116]  In this milieu his paraphrasis of the De Caelo, lost in Greek, was also translated (by Abu Bishr Matta) and revised (by Yahya ibn  ʿAdi).[117]  Abu Bishr Matta translated from Syriac into Arabic three other works: the paraphrasis of the Posterior Analytics, that of Book Lambda of the Metaphysics, and a writing connected with the  Topics.[118]
