The Defeat of the Beast of the Apocalypse

A knight wearing a coif and hauberk of chainmail, with a crown atop his head, sits upon a white horse, driving a long lance into the throat of a monstrous creature. The creature has multiple canine-like heads and a large, gaping, reptilian-toothed jaw; blood streaks from its wounds. The background features a red, grid-like pattern, and the scene is framed within a rectangular border.

This illumination is derived from the Book of Revelation (Apocalypse), specifically depicting the eschatological combat between the forces of Christ and the Beast. It belongs to the tradition of medieval 'Apocalypse' manuscripts, which were widely produced in the 13th century to illustrate the prophetic visions of John of Patmos.
