The chronology of the fourth-beast symbol is determinable by the career of the little horn. The fourth-beast system was to continue, at least, a time, times, and a half, from the time the little horn made its appearance, after the end of which, it was to be destroyed by divine judgment, and the dominion transferred to the saints. Hence, if we can identify the little horn in history, and fix the date of its appearance, we shall be enabled to arrive at a correct conclusion as to the arrival of the time of the fourth-beast destroying judgment to take effect in the coming of the Ancient of Days, in the person of Jesus, to put an end to the arrogant blasphemies which prevail for time, times, and a half time. To do this, we must give a little attention to the appearance of the ten horns, of the fourth beast, as the ten horns precede the advent of the little horn power. This takes us back to what is called "the fall of the Roman empire," when "the fourth kingdom" passed from its imperial to its divided and multiregal phase.
