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. Volume 2 (1861) of Tregelles' landmark seven-volume edition begins with a description of the many manuscripts consulted. Tregelles refers to the anticipated publication of the Codex Sinaiticus described by Tischendorf, and to the work of Hort and Westcott. This volume contains the Greek text of the Gospels of Luke and John together with Jerome's Latin Vulgate text, indications of manuscripts used, Biblical cross-references, and a full critical apparatus.
