A painstaking compiler of catalogues and indexes, the biblical scholar and bibliographer Thomas Hartwell Horne (1780-1862) first published his most famous work in 1818, having begun his research for it many years earlier in 1801. Reissued here in five parts is the expanded four-volume tenth edition of 1856, which includes revisions by the scholars Samuel Davidson (c.1806-98) and Samuel Prideaux Tregelles (1813-75). This monumental and influential work of nineteenth-century biblical scholarship remains a valuable resource for modern researchers, reflecting the methods and perspectives of its era. Volume 4, rewritten by Tregelles for this edition, addresses textual criticism of the New Testament. Drawing strongly on his previous scholarship, Tregelles covers the history of the text, distinguished readings and important manuscripts, and he provides an introduction to each book of the New Testament.
