Wadi El Natrun
In 1912, F. C. Burkitt discovered an older manuscript of the Odes of Solomon in the British Museum (BM Add. 14538). The "Codex Nitriensis" came from the Monastery of the Syrian in Wadi El Natrun, sixty miles west of Cairo. It presents Ode 17:7b to the end of Ode 42, followed by the Psalms of Solomon in one continuous numbering. Nitriensis is written in far denser script than the Harris manuscript, which often makes it illegible. However, Nitriensis is earlier than Harris by about five centuries (although Mingana dated it to the 13th century).
