Origene bizantino. I Commenti a Matteo e Giovanni da Mistrá a Venezia.

This paper tries to shed light on some moments of the byzantine tradition of Origen. Particular attention is paid to the transmission of the Commentary on Matthew: the codex Marc. Gr. 43 is shown to have been copied in Mystras for the emperor John VI Cantacuzenus, who took inspiration from the Commentary for his theological treaties, as proved by a reading note here transcribed. The following owner of the manuscript was Bessarion, who plaved a fundamental role in the circulation of Origen's writings and expressed great admiration for the heretic theologian of Alexandria. From a strictly philological point of view, Marc. Gr. 43 is demonstrated to be not a simple copy of Monac. Gr. 191 but to be the result of a probable contamination and to contain conjectures by the scribe himself. It is finally argued that the división between books X and XI of the Commentary on Matthew originated in the Marc. Gr. 43 and can't consequently be considered original. [ABSTRACT FROM AUTHOR]
