It was Carl LACHMANN (1793-1851) who first broke with the Textus Receptus altogether. He was a master in the domain of textual criticism. He distinguished himself first in the department of classical and Teutonic philology, but came afterwards to render equal service to the textual criticism of the New Testament. His object was to restore the text to the form in which it had been read in the ancient Church about the year 380, going on the ground of the oldest known Greek and Latin manuscripts, _i.e._ the oldest Eastern and Western authorities.[14] He did not claim to go further back than that date with any certainty. But it was still open to question whether that were not possible, and whether the grounds on which Lachmann’s work was based might not be still further extended and confirmed. [Sidenote: Tischendorf.] 11. The task which Lachmann set before him was prosecuted with the most brilliant success in and from Germany by Gottlob (Aenotheus) Friedrich Constantin von TISCHENDORF (b. 18th January 1815, d. 7th December 1874). In the course of several tours, first in Europe and afterwards in the East, from the year 1841 onwards, he discovered and collated a number of the most important and ancient manuscripts of the Bible. Among these the most notable was the Codex Sinaiticus, found by him on Mount Sinai in 1859, and now in St. Petersburg, the oldest known manuscript of the present day which contains the entire Greek New Testament. On the basis of the material collected by himself and others, Tischendorf prepared eight different editions between 1841 and 1872.[15] His seventh edition, consisting of 3500 copies, appeared in 1859, previous to the discovery of the Sinaiticus. The text of this edition differed from that of 1849 in 1296 instances, of which no fewer than 595 were reversions to the Textus Receptus. The text of the last edition, the octava critica maior, which was issued complete in eleven parts between 1864 and 1872, differed from that of the seventh in 3572 places. The third volume of the editio octava maior, containing the Prolegomena, was completed in three parts, extending to 1428 pages, by Caspar René Gregory between 1884 and 1894, a work which affords the most complete survey of what has been done on the Greek New Testament up to the present time.
