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 4 (1869) of Tregelles’ landmark seven-volume edition begins with a description of the many manuscripts consulted. This volume contains Romans to 2 Thessalonians (ending at chapter 3 verse 3, with the remaining pages appearing in Volume 5). As well as the Greek text, each page has Jerome’s Latin Vulgate text in the right margin, indications of manuscripts used and Biblical cross-references in the left margin, and a full textual apparatus at the foot.
