Nag Hammadi Codex XIII (designated by siglum NHC XIII) is a papyrus codex with a collection of early Christian Gnostic texts in Coptic (Sahidic dialect).
The manuscript is generally dated to the 4th century, though there is some debate regarding the original composition of the texts.
The nomina sacra are contracted in an unusual way (ΠΝΑ, ΧΣ, ΧΡΣ, ΙΗΣ), the words at the end of line are abbreviated.
[8] The so-called "Codex XIII" is in fact not a codex, but rather the text of Trimorphic Protennoia, written on "... eight leaves removed from a thirteenth book in late antiquity and tucked inside the front cover of the sixth.
"[9][10] Only a few lines from the beginning of Origin of the World are discernible on the bottom of the eighth leaf.
