On the one hand:
Pope Benedict XVI
The Book of Daniel, in the form in which we have it, is generally dated on good grounds to the years between 167 and 163 B.C., that is, the period of the harshest persecution of Israel's faith by the Hellenistic King Antiochus IV Epiphanes. In this extreme tribulation, in which the faith of the people of God, its historical hope, seems once and for all to have been reduced ad absurdum, the seer gains a new vision of the totality of history.

On the other hand:
Porphyry wrote his twelfth book against the prophecy of Daniel, denying that it was composed by the person to whom it is ascribed in its title, but rather by some individual living in Judaea at the time of the Antiochus who was surnamed Epiphanes. He further alleged that “Daniel” did not foretell the future so much as he related the past, and lastly that whatever he spoke of up till the time of Antiochus contained authentic history, whereas anything he may have conjectured beyond that point was false, inasmuch as he would not have foreknown the future. Eusebius, Bishop of Caesarea, made a most able reply to these allegations in three volumes, that is, the eighteenth, nineteenth, and twentieth. Appollinarius did likewise, in a single large book, namely his twenty-sixth. Prior to these authors Methodius made a partial reply.
For the benefit of us who are Christians, I wish to stress in my preface this fact, that none of the prophets has so clearly spoken concerning Christ as the prophet Daniel. For not only did he assert that He would come, a prediction common to the other prophets as well, but also he set forth the very time at which He would come. Moreover he went through the various kings in order, stated the actual number of years involved, and announced beforehand the clearest signs of events to come. And because Porphyry saw that all these things had been fulfilled and could not deny that they had taken place, he overcame this evidence of historical accuracy by taking refuge in this evasion, contending that whatever is foretold concerning Antichrist at the end of the world was actually fulfilled in the reign of Antiochus Epiphanes, because of certain similarities to things which took place at his time. But this very attack testifies to Daniel’s accuracy. For so striking was the reliability of what the prophet foretold, that he could not appear to unbelievers as a predicter of the future, but rather a narrator of things already past.
