Abstract
Following the edition of the works of Ps. Justin by B. Pouderon, this article presents some critical notes concerning de monarchia and the Cohortatio ad Graecos. Notwithstanding the significant relationship with Clement of Alexandria, the de monarchia in fact comes from the Judeo-Hellenic background of Alexandria. The work was composed in the context of the anti-polytheistic controversy, and lacks the detail which would indicate a Christian origin. Concerning the Cohortatio it is suggested that due to its linguistic characteristics the probable author is Marcellus of Ancyra, despite the fact that neither the doctrine nor the exegesis support this assumption.
