Prior to the discovery and publication of the codex, Carl Schmidt identified a similar biographical composition (although in Coptic) among the Medinet Madi find of Coptic Manichaean texts. Unfortunately that text was never published, and it was lost during the Second World War. See Schmidt and H. Jacob Polotsky, Ein Mani-Fund in Ägypten: Originalschriften des Mani und seiner Schüler (Berlin: Akademie der Wissenschaften, 1933), pp. 26–29.
