Author of the Book of Daniel

Daniel was the author of this book according to Jewish tradition, and this was confirmed by Jesus himself, but there has been considerable criticism about the book of Daniel because of the accuracy of the prophecies. Many claim that these had to been written after the fact, and that Daniel could not possibly have known so much detail about the future. The first major critic of the genuineness of the book of Daniel was Porphyry of Tyre, a Greek philosopher of the third century AD who claimed that the book of Daniel had been written by a person living in the second century BC during the reign of Antiochus Epiphanes. His main reason for rejecting the book of Daniel was centered around the person of Antiochus Epiphanes, whom Daniel claimed was a prototype of the Antichrist. Daniel's prophecies written a few hundred years prior but were very very accurate in their detail. Many other critics have tried to discredit the book of Daniel, but the Bible and history have confirmed that Daniel was the author of this book, and therefore was written at the time of the Persian Empire (sixth century BC).
