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.
