The conclusion is obvious; and it is equally obvious that, when we suppose the name of Daniel to have been assumed, and the assumption to have been supported by an antique colouring, we do not for a moment charge the unknown author--who may very well have been Onias IV.--with any dishonesty. Indeed, it appears to us that there are many traces in the Book--φωνᾶντα συνετοῖσιν--which exonerate the writer from any suspicion of _intentional_ deception. They may have been meant to remove any tendency to error in understanding the artistic guise which was adopted for the better and more forcible inculcation of the lessons to be conveyed. That the stories of Daniel offered peculiar opportunities for this treatment is shown by the apocryphal additions to the Book; and that the practice was well understood even before the closing of the Canon is sufficiently shown by the Book of Ecclesiastes. The writer of that strange and fascinating book, with its alternating moods of cynicism and resignation, merely adopted the name of Solomon, and adopted it with no dishonourable purpose; for he could not have dreamed that utterances which in page after page betray to criticism their late origin would really be identified with the words of the son of David a thousand years before Christ. This may now be regarded as an indisputable, and is indeed a no longer disputed, result of all literary and philological inquiry. It is to Porphyry, a Neoplatonist of the third century (born at Tyre, A.D. 233; died in Rome, A.D. 303), that we owe our ability to write a continuous historical commentary on the symbols of Daniel. That writer devoted the twelfth book of his Λόγοι κατὰ Χριστιανῶν to a proof that Daniel was not written till _after_ the epoch which it so minutely described.[174] In order to do this he collected with great learning and industry a history of the obscure Antiochian epoch from authors most of whom have perished. Of these authors Jerome--the most valuable part of whose commentary is derived from Porphyry--gives a formidable list, mentioning among others Callinicus, Diodorus, Polybius, Posidonius, Claudius, Theo, and Andronicus. It is a strange fact that the exposition of a canonical book should have been mainly rendered possible by an avowed opponent of Christianity. It was the object of Porphyry to prove that the apocalyptic portion of the Book was not a prophecy at all.[175] It used to be a constant taunt against those who adopt his critical conclusions that their weapons are borrowed from the armoury of an infidel. The objection hardly seems worth answering. "_Fas est et ab hoste doceri._" If the enemies of our religion have sometimes helped us the better to understand our sacred books, or to judge more correctly respecting them, we should be grateful that their assaults have been overruled to our instruction. The reproach is wholly beside the question. We may apply to it the manly words of Grotius:
