Book excerpt: The Apocalypse of John is perhaps the most alluring and dangerous text in any scripture. This study looks at English responses to it in political pamphlets and scholarly exegesis, in poetry and preaching and visual art. Those who set out to find enduring meaning in the book failed. Yet in the post-Christian re-writings of Revelation by Shelley and Blake, John's own dynamic of unveiling comes to life, subverting the structures of power and reading built on the visions of Patmos.
