Adso of Montier-en-Der

Prophesied a King of the Franks, who will become the last and greatest Emperor, restoring the Roman Christian Empire. After his reign, he will journey to Jerusalem, lay down his crown on the Mount of Olives, and die there. This act will conclude the dignity of the Roman Empire. Afterwards, the period of Antichrist and the final tribulation will begin. His account shaped later medieval expectations of the "Great Monarch" and end-times.

Describes Antichrists origin, Jewish descent, and rise from obscurity. He asserts false miracles, reigns from Jerusalem, persecutes Christians for three and a half years, and marks his followers. Ultimately, he will be defeated by Christ at His Second Coming, ushering the last judgment. This work details classic medieval beliefs about Antichrists reign and characteristics.
