George Howard considered that the change to the "nomina sacra" and instead of YHWH in Christian copies of the Septuagint took place "at least by the beginning of the second century": it began "towards the end of the first century", and "somewhere around the beginning of the second century [...] must have crowded out the Tetragram in both Testaments". Already by the late second century "nomina sacra" were used not only in New Testament manuscripts but also in inscriptions in Lycaonia (modern central Turkey). David Trobisch proposes that the replacement of "YHWH" to "nomina sacra" was a conscious editorial decision at the time of compiling both New and Old Testaments, in the second century.
