Codex Chisianus 45 (also Codex Chigianus 45; Vatican Library, Chigi R. VII 45; numbered 88 in Rahlfs Septuagint manuscripts, 87 in Field's Hexapla) is a 10th-century biblical manuscript, first edited in 1772. The content of the so-called Syro-Hexaplar Codex (dated 616/7), which contains a Syriac translation of Origen's recension, has been adduced to corroborate the authenticity of the Greek text of Codex Chisianus. The Septuagint text of the Book of Daniel had disappeared almost entirely from Greek tradition at the end of the 4th century, being superseded by the revised text of Theodotion.
