Page from the Beatus Manuscript in the Escorial Museum, Spain.


These manuscripts are richly-illustrated versions of a famous commentary on the Revelation of St John the Divine
penned by a monk called Beatus in the Northern Spanish monastery of Liébana in the 9th century.

On this page an Angel of the Apocalypse is emprisoning in everlasting stocks the conquered Satan ,
a sexless figure whose feet and hands nevertheless are curiously similar to those of sheela-na-gigs.
