Moreover, the clay tablets on which the past history of Canaan could be read were preserved in the libraries and archive-chambers of the Canaanitish cities down to the time when the latter were destroyed. If any doubt had existed on the subject after the revelations of the Tel el-Amarna tablets, it has been set at rest by the discovery of a similar tablet on the site of Lachish. In some cases the cities were not destroyed, so far as we know, until the period when it is allowed that the Israelites had ceased to be illiterate. Gezer, for example, which plays a leading part in the Tel el-Amarna correspondence, does not seem to have fallen into the hands of an enemy until it was captured by the Egyptian Pharaoh and handed over to his son-in-law Solomon. As long as a knowledge of the cuneiform script continued, the early records of Canaan were thus accessible to the historian, many of them being contemporaneous with the events to which they referred. A single archæological discovery has thus destroyed the base of operations from which a one-sided criticism of Old Testament history had started. The really strong point in favour of it was the assumption that the Mosaic age was illiterate. Just as Wolf founded his criticism and analysis of the Homeric Hymns on the belief that the use of writing for literary purposes was of late date in Greece, so the belief that the Israelites of the time of Moses could not read or write was the ultimate foundation on which the modern theory of the composition of the Hexateuch has been based. Whether avowed or not, it was the true starting-point of critical scepticism, the one solid foundation on which it seemed to rest. The destruction of the foundation endangers the structure which has been built upon it. In fact, it wholly alters the position of the modern critical theory. The _onus probandi_ no longer lies on the shoulders of the defenders of traditional views. Instead of being called upon to prove that Moses could have written a book, it is they who have to call on the disciples of the modern theory to show reason why he should not have done so. And it is always difficult to prove a negative.
