Known for his prophetic and imaginative works of poetry, painting, and printmaking, William Blake was also a prolific reader and annotator of other writers' works. This is the first work of criticism to consider Blake's annotations in their entirety, and it covers such topics as art, poetry, theology, madness and philosophy, as well as the authors Lavater, Swedenborg, Bacon, Spurzheim, Berkeley, and Wordsworth, among others.
