P. Lond.Lit.207 (BL P.Inv.Nr.230, TM 62310 / LDAB 3473) is a Greek fragment of a Septuagint manuscript written on papyrus in codex form.
[2] According to Don C. Barker, this papyrus proposes evidence about the origin of nomina sacra: Why is θεός, which is always treated in Christian texts as a nomen sacrum, written uncontracted in P.Lond.Lit.
Judging by the various ways the Tetragrammaton was written in the text of the Greek Old Testament, it appears that scribes struggled with the problem of how to present it.
Some left a space in which the Hebrew word was to be written later; others used paleo-Hebrew writing, whilst others wrote the Greek letters Ι.Α (sic) or ΠΙΠΙ and it seems that in some cases κύριος was used instead of the Tetragrammaton.
(…) Did a scribe or scribes use this contracted form for personal names to signal to the reader that κύριος, when so contracted, is being used for the personal name of the Hebrew deity and so distinguish it from its usual non-personal use as master or lord?
