With the exception of Ezekiel, Haggai, Zechariah, and Joel, all the prophecies which come from the centuries following the fall of Jerusalem in 586 B.C. are anonymous. The worship of the authority of the past had begun, and there is evidence that the belief was gaining currency that the days of the prophets were past. Hence the natural tendency to resort to anonymous authorship or else to append a later message to an earlier prophecy. Chapters ix.-xiv. of the book of Zechariah illustrate this custom,--chapters which apparently come from the last Old Testament period, the Greek or Maccabean. The habit of presenting prophetic truth in the highly figurative, symbolic form, of the apocalypse also became prominent in later Judaism. This has already been noted in the study of the growth of the New Testament, and is illustrated by the book of Revelation. It was especially adapted to periods of religious persecution, for it enabled the prophet to convey his message of encouragement and consolation in language impressive and clear to his people, yet unintelligible to their foreign masters. [Sidenote: _The historical background of the book of Daniel_] To the mind of one who has carefully studied the book of Daniel in the light of the great crisis that came to the Jews as a result of the relentless persecutions of Antiochus Epiphanes, between the years 169 and 165 B.C., there remains little doubt that it is in this period the wonderful apocalypse finds its true setting and interpretation. The familiar examples of the heroic fidelity of Daniel and his friends to the demands of their religion and ritual were supremely well adapted to arouse a similar resistance toward the demands of a tyrant who was attempting to stamp out the Jewish, religion and transform the chosen people into a race of apostates. The visions found in the book trace rapidly, in succession, the history of the Babylonian, Median, Persian, and, last of all, the Greek kingdoms. The culmination is a minute description of the character and reign, of the tyrant Antiochus Epiphanes (xi. 21-45). He is clearly the little horn of chapter viii. But suddenly, in the midst of the account of the persecutions, the descriptions become vague and general. Nor is there any reference to the success of the Maccabean uprising; instead, the prediction is made that Jehovah himself will soon come to establish his Messiah's kingdom.
