Papyrus Oxyrhynchus 157
Papyrus Oxyrhynchus 157 (P. Oxy. 157 or P. Oxy. I 157) is a letter, written in Greek and discovered in Oxyrhynchus. The manuscript was written on papyrus in the form of a sheet. The document was written in the 6th century. Currently it is housed in the Egyptian Museum (10042) in Cairo.
The document is a letter concerning a dispute between Papnouthius, a monk, and a scribe, about a measure of some sort. The word in question is diapismatos (διαπίσματος). The only other known use is in P. Oxy. 133, line 14. Grenfell and Hunt state that "in the absence of other parallels the meaning is doubtful." The measurements of the fragment are 132 by 306 mm.
