At this time Shamis-shum-ukim joined in the great revolt to which we have referred in a foregoing paragraph of this chapter. There are two accounts in the archeological records as to the end of Shamis-shum-ukim. Although a twin brother of Assur-bani-pal, he was some hours the younger, and thus was nominally subject to him under Assyrian law. One account says that he was taken prisoner and that Assur-bani-pal had him burned at the stake. The other account says that Shamis-shum-ukim, seeing he was about to be defeated, locked himself in a small section of the palace, which he set afire and burned himself rather than surrender. There was at this time a revolt in the Egyptian section of the empire which resulted in some long conflicts, which are also given in these records. It was also at this period that Assur-bani-pal left the record above cited, of the pacification of Babylon and the submission of Josiah. The British Museum has a very large collection of letters from the library of Assur-bani-pal at Nineveh, many of which are of high significance in the study of these historical episodes. These letters cover a broad scope as they include the reports, requisitions, and communications of dignitaries. Some of these came from the crown prince, others from local governors and still more from various military captains. They deal in specific detail with military operations, uprisings, rebellions, and their suppression. They tell of the dispatch of troops to the provinces, with lists of expenses and expenditures. Such intimate details of Assyrian science as the reports of astronomers for regulating the calendar of the year are found there, and illuminating comments upon the political trend of the days. There are many references to these episodes, as would naturally be expected. One of the great monuments to be found in the Babylonian Room of the British Museum, and numbered 90,864, is a stone stele with a rounded top, that is a treasure indeed. The upright full-length figure of Assur-bani-pal is shown in his capacity of high priest. This stele contains a lengthy chronicle recording the names, honors, and genealogy of the monarch and tells of his godly conduct and fidelity to his religion. There is a note of sadness and an index to the character of this great Assyrian in the line where Assur-bani-pal declares that he himself had appointed his twin brother Shamis-shum-ukim “to the sovereignty over Babylon so that the strong may not oppress the weak.”
