Samuel Prideaux Tregelles (1813–1875) was a Cornish-born Biblical scholar who travelled to major libraries all over Europe in order to study ancient manuscripts. Biblical textual criticism was a burgeoning new field in the mid-nineteenth century, with leading scholars including Lachmann and Tischendorf in Germany and Tregelles' contemporaries Scrivener, Westcott and Hort in England all working towards the ideal of a more authoritative Greek New Testament text than had previously been available. This volume contains the short Volumes 5 (1870) and 6 (1872) of Tregelles' edition (the Epistles continued, and Revelation), which the author had originally intended to publish together, along with the posthumous Volume 7 (1879) containing Prolegomena (compiled by F. J. A. Hort and A. W. Streane from earlier publications by Tregelles), and additional collations of parts of Codex Sinaiticus and Codex Vaticanus. The Greek text is accompanied by Jerome's Latin Vulgate and a full textual apparatus.
