Daniel is a book of apocalypse, a book of revelation, with a common theme that is in many apocalyptic books such as Isaiah, Zechariah and the Revelation of John. These books are filled with evil and war, dreams and visions, figures and symbols and with the message that God's judgment is imminent and that one must repent and turn from their evil ways. The most intriguing parts of Daniel are the prophecies that are spoken and the interpretations of dreams that all seem to have a common thread. These prophecies are interpreted by many as prophecies of both Daniels near term and in his lifetime and prophecies telling of things that will come even in our future in the "end times." Others simply take the writings as stories attributed to Daniel, but written as prophecies by others in apocalyptic form and analogies of historical events to the true writer.
