This article revisits the evidence for the inclusion of Clementine writings in Syriac Biblical manuscripts—1 and 2 Clement, the two epistles De virginitate, and the Eight Books of Clement—introduces a series of new witnesses, identifies a likely cause for this inclusion (medieval rather than early Christian), and contends that, despite current assumptions in the field to the contrary, this is a case where the later, pseudepigraphic works influence and determine the reception of the older, “genuine” writing, rather than the other way around.
