Forthcoming in JTS (and now available as an advance publication on the journal’s website) is Lincoln H. Blumell “P.Mich. Inv. 4461KR: the earliest fragment of the Didascalia CCCXVIII patrum“.
Abstract: This article presents an edition of a previously unpublished literary papyrus in the University of Michigan collection that preserves a section from a text typically known by the designation Didascalia CCCXVIII Patrum Nicaenorum (CPG 2298). The papyrus, which appears to date to the fifth century ad, is important because it is only known ancient Greek witness to this treatise and attests a previously unknown textual variant.
