The Book is the earliest specimen of its kind known to us. It inaugurated a new and important branch of Jewish literature, which influenced many subsequent writers. An apocalypse, so far as its literary form is concerned, "claims throughout to be a supernatural revelation given to mankind by the mouth of those men in whose names the various writings appear." An apocalypse--such, for instance, as the Books of Enoch, the Assumption of Moses, Baruch, 1, 2 Esdras, and the Sibylline Oracles--is characterised by its enigmatic form, which shrouds its meaning in parables and symbols. It indicates persons without naming them, and shadows forth historic events under animal forms, or as operations of Nature. Even the explanations which follow, as in this Book, are still mysterious and indirect.
II. In the next place an apocalypse is literary, not oral. Schürer, who classes Daniel among the oldest and most original of _pseudepigraphic prophecies_, etc., rightly says that "the old prophets in their teachings and exhortations addressed themselves directly to the people first and foremost through their oral utterances; and then, but only as subordinate to these, by written discourses as well. But now, when men felt themselves at any time compelled by their religious enthusiasm to influence their contemporaries, instead of directly addressing them in person like the prophets of old, they did so by a writing purporting to be the work of some one or other of the great names of the past, in the hope that in this way the effect would be all the surer and all the more powerful."[156] The Daniel of this Book represents himself, not as a prophet, but as a humble student of the prophets. He no longer claims, as Isaiah did, to speak in the Name of God Himself with a "Thus saith Jehovah."
III. Thirdly, it is impossible not to notice that Daniel differs from all other prophecies by its all-but-total indifference to the circumstances and surroundings in the midst of which the prediction is supposed to have originated. The Daniel of Babylon and Susa is represented as the writer; yet his whole interest is concentrated, not in the events which immediately interest the Jews of Babylon in the days of Cyrus, or of Jerusalem under Zerubbabel, but deals with a number of predictions which revolve almost exclusively about the reign of a very inferior king four centuries afterwards. And with this king the predictions abruptly stop short, and are followed by the very general promise of an immediate Messianic age.
