Illustrated Beatus manuscripts bring to life an extraordinary vision of the end of the world, as recorded by Saint John in the Apocalypse (Book of Revelation) and filtered through the lens of Beatus of Liébana, an eighth-century Asturian monk. These manuscripts are unique to medieval Spain and a testament to the pervasive artistry and intellectual milieu of monastic culture there. The leaf shown here comes from a manuscript disassembled in the 1870s.This table was created in an attempt to calculate the numerical "code" of the Antichrist, who was a particularly troubling figure to Christians of the Middle Ages. Saint John asserted in Apocalypse 13.18 that the "number of the beast…is 666," the number specifically linked to the devil at the time the Apocalypse was written. Here, the eight names given to the Antichrist are lettered in red in vertical columns; each letter is assigned a number. The total given is 666, written four times diagonally in the center of the table.
