Textual overlaps exist between the material common to certain Messianic-apocalyptic material in the Mingana and Grebaut manuscripts, and material published by Ismail Poonawala. The manuscripts having the "Book of the Rolls" structure generally contain a recension of the well-known "Treasure Grotto" text. The plenary manuscripts also generally contain an "Acts of Clement" work that roughly corresponds to the narrative or "epitome" story of Clement of Rome, known to specialists in pseudo-Clementine literature. Finally, some of the plenary manuscripts also contain "apostolic church order" literature; a collation of that has also been presented at a conference of the "Association pour l'Etudes des Apocryphes Chretiennes".
