Samuel Prideaux Tregelles (1813-1875) was a Cornish-born Biblical scholar who travelled to major libraries all over Europe 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. Tregelles begins Volume 1 (1857) of his seven-volume edition with an explanation of his editorial principles and a description of the many manuscripts consulted, whether whole codices or separate leaves. This volume contains the Gospels of Matthew and Mark. 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.
