A review from amazon.com:
Serious students of Blake would do well to start here. Lucid, informed and methodical, Bloom's "Blake's Apocalypse" leaves no page unturned amid his exhaustive investigation into the influences, ideas and hopes that comprise Blake's vast and complicated "poetic argument." Though Bloom's erudition can sometimes undermine his clarity, the book glows with the confident understanding and purpose he built his name on. Delving into Blake's main influences -- Milton, the Bible and the ancient Greeks -- Bloom focuses much of his time on Blake's epics while making the good point that these greater works are often neglected in favor of the more managable and straightforward "Songs of Innocence and Experience." "Blake's Apocalypse" is an endless resource comparable to those other masterpieces of Blake scholarship: Frye's "Fearful Symmetry" and Erdman's "Prophet Against Empire."
