The Manuscripts of the Commentary to the Apocalypse (Beatus of Liébana).

The manuscripts known as Beatus are a series of codices and fragments that contain the copy of the Commentary to Apocalypse, attributed to the monk Beatus of Liébana, who lived in the North the Iberian Peninsula in the second half of the 8th century. They’re considered the most beautiful and original manuscripts produced by medieval western civilization and have inspired some of the most famous contemporary literary and artistic works. They provide material proof of the transition from the Ancient World to the Medieval times in the fields of art, literacy and thought in the Mediterranean world and Western Europe.
