In the 8th century, in a monastery in the mountains of northern Spain, 700 years after the Book of Revelation was written, a monk named Beatus set down to illustrate a collection of writings he had compiled about this most vivid and apocalyptic of the New Testament books. Throughout the next few centuries his depictions of multi-headed beasts, decapitated sinners, and trumpet blowing angels, would be copied over and over again in various versions of the manuscript. Below is a selection of images from one such manuscript known as the Beatus de Facundus (or Beatus de León), dating to 1047 and painted by a man called Facundus for Ferdinand I and Queen Sancha. It is composed of 312 leaves and 98 miniatures.
