In the last years, two scholars (Panayiotis Tzamalikos and Ronald H. Heine) have proposed a new dating for Origen’s Against Celsus and Commentary on Matthew. Since these works are among the last ones of this author, their hypotheses also imply that Origen’s death occurred much later than commonly believed. This paper discusses Tzamalikos’ and Heine’s arguments. A thorough examination will show that they are not strong enough to justify significant changes in Origen’s biography: the traditional dating of Against Celsus and Commentary on Matthew (248-249) remains the most likely./
