I recently edited together with Einar Thomassen a parchment folio owned by the Norwegian collector Martin Schøyen. The Schøyen leaf (MS 1991) was immediately followed in the codex by another dismembered fragment which ended up in the Bibliothèque Nationale in Paris. They seem to belong to an unknown apocryphal writing, although the echoes it contains of fifth century Christological debates should warn against regarding it as an early document.
