In the year 1835, the same year in which Strauss' _Leben Jesu_ saw the light, Wilhelm Vatke published his _Religion des Alten Testaments_. Vatke was born in 1806, began to teach in Berlin in 1830, was professor extraordinarius there in 1837 and died in 1882, not yet holding a full professorship. His book was obscurely written and scholastic. Public attention was largely occupied by the conflict which Strauss' work had caused. Reuss in Strassburg was working on the same lines, but published the main body of his results much later. The truth for which these scholars and others like them argued, worked its way slowly by force of its own merit. Perhaps it was due to this fact that the development of Old Testament critical views was subject to a fluctuation less marked than that which characterised the case of the New Testament. It is not necessary to describe the earlier stages of the discussion in Vatke's own terms. To his honour be it said that the views which he thus early enunciated were in no small degree identical with those which were in masterful fashion substantiated in Holland by Kuenen about 1870, in Germany by Wellhausen after 1878, and made known to English readers by Robertson Smith In 1881. Budde has shown in his _Kanon des Alten Testaments_, 1900, that the Old Testament which lies before us finished and complete, assumed its present form only as the result of the growth of several centuries. At the beginning of this process of the canonisation stands that strange event, the sudden appearance of a holy book of the law under King Josiah, in 621 B.C. The end of the process, through the decisions of the scribes, falls after the destruction of Jerusalem, possibly even in the second century. Lagarde seems to have proved that the rabbis of the second century succeeded in destroying all copies of the Scripture which differed from the standard then set up. This state of things has enormously increased a difficulty which was already great enough, that of the detection and separation of the various elements of which many of the books in this ancient literature are made up. Certain books of the New Testament also present the problem of the discrimination of elements of different ages, which have been wrought together into the documents as we now have them, in a way that almost defies our skill to disengage. The synoptic Gospels are, of course, the great example. The book of the Acts presents a problem of the same kind. But the Pentateuch, or rather Hexateuch, the historical books in less degree, the writings even of some of the prophets, the codes which formulate the law and ritual, are composites which have been whole centuries in the making and remaking. There was no such thing as right of authorship in ancient Israel, little of it in the ancient world at all. What was once written was popular or priestly property. Histories were newly narrated, laws enlarged and rearranged, prophecies attributed to conspicuous persons. All this took
