A portion of the Codex Sinaiticus, from one of the leaves that at the time was at the University of Leipzig, containing Esther 2:3-8. (The majority of the manuscript is now at the British Library, London: the other parts are in Leipzig, the National Library at St. Petersburg, Russia, and St Catherine's Monastery at Sinai in Egypt.) It is generally believed to have been written in the mid-fourth century.
