Illustrations of The Book of Job by William Blake. Illustrations of the Book of Job Invented and Engraved by William Blake. William Blake's Illustrations of the Book of Job primarily refers to a series of twenty-two engraved prints (published 1826) by Blake illustrating the biblical Book of Job. It also refers to two earlier sets of watercolours by Blake on the same subject (1806 and 1821). The engraved Illustrations are considered to be Blake's greatest masterpieces in the medium of engraving, and were also a rare commercial and critical success for Blake. The Book of Job was an important influence upon Blake's writings and art; Blake apparently identified with Job, as he spent his lifetime unrecognized and impoverished. Harold Bloom has interpreted Blake's most famous lyric, The Tyger, as a revision of God's rhetorical questions in the Book of Job concerning Behemoth and Leviathan. Blake also depicted the story of Job throughout his career as an artist. The song of Enion in Night the Second of The Four Zoas also demonstrates that Blake identified with Job.
