X. In chap. iv. we have another monotheistic decree of the King of Babylon, announcing to "all people, nations, and languages" what "the high God hath wrought towards me." It gives us a vision which recalls Ezek. xxxi. 3-18, and may possibly have been suggested by that fine chapter.[115] The language varies between the third and the first person. In iv. 13 Nebuchadrezzar speaks of "a watcher and a holy one." This is the first appearance in Jewish literature of the word _'ir_, "watcher," which is so common in the Book of Enoch.[116] In ver. 26 the expression "after thou shalt have known that _the heavens_ do rule" is one which has no analogue in the Old Testament, though exceedingly common in the superstitious periphrases of the later Jewish literature. As to the story of the strange lycanthropy with which Nebuchadrezzar was afflicted, though it receives nothing but the faintest shadow of support from any historic record, it may be based on some fact preserved by tradition. It is probably meant to reflect on the mad ways of Antiochus. The general phrase of Berossus, which tells us that Nebuchadrezzar "fell into a sickness and died,"[117] has been pressed into an historical verification of this narrative! But the phrase might have been equally well used in the most ordinary case,[118] which shows what fancies have been adduced to prove that we are here dealing with history. The fragment of Abydenus in his _Assyriaca_, preserved by Eusebius,[119] shows that there was _some_ story about Nebuchadrezzar having uttered remarkable words upon his palace-roof. The announcement of a coming irrevocable calamity to the kingdom from a Persian mule, "the son of a Median woman," and the wish that "_the alien conqueror_" might be driven "through the desert where wild beasts seek their food, and birds fly hither and thither," has, however, very little to do with the story of Nebuchadrezzar's madness. Abydenus says that, "when he had thus prophesied, he suddenly vanished"; and he adds nothing about any restoration to health or to his kingdom. All that can be said is that there was current among the Babylonian Jews some popular legend of which the writer of the Book of Daniel availed himself for the purpose of his edifying _Midrash_.
