This version of the Old Testament is a translation of the Septuagint by Sir Lancelot Charles Lee Brenton, originally published by Samuel Bagster & Sons, London, in 1844, in English only. From the 1851 edition the Apocrypha were included, and by about 1870, there was an edition with parallel Greek text, another one appearing in 1884. In the 20th century it was reprinted by Zondervan among others.
Codex Vaticanus is used as the primary source. Brenton's has been the most widely used translation until the publication of New English Translation of the Septuagint in 2007.
