The prophetic books of the 18th-century English poet and artist William Blake are a series of lengthy, interrelated poetic works drawing upon Blake's own personal mythology. They have been described by 20th-century critic Northrop Frye as forming "what is in proportion to its merits the least read body of poetry in the English language". While Blake worked as a commercial illustrator, these books were ones that he produced, with his own engravings, as an extended and largely private project.
William Blake (28 November 1757 – 12 August 1827) was an English poet, painter, and printmaker. Largely unrecognised during his life, Blake has become a seminal figure in the history of the poetry and visual art of the Romantic Age. What he called his "prophetic works" were said by 20th-century critic Northrop Frye to form "what is in proportion to its merits the least read body of poetry in the English language". While he lived in London his entire life, except for three years spent in Felpham, he produced a diverse and symbolically rich collection of works, which embraced the imagination as "the body of God", or "human existence itself".
Although Blake was considered mad by contemporaries for his idiosyncratic views, he came to be highly regarded by later critics and readers for his expressiveness and creativity, and for the philosophical and mystical undercurrents within his work. His paintings and poetry have been characterised as part of the Romantic movement and as "Pre-Romantic". A theist who preferred his own Marcionite style of theology, he was hostile to the Church of England (indeed, to almost all forms of organised religion), and was influenced by the ideals and ambitions of the French and American Revolutions. Although later he rejected many of these political beliefs, he maintained an amicable relationship with the political activist Thomas Paine; he was also influenced by thinkers such as Emanuel Swedenborg. Despite these known influences, the singularity of Blake's work makes him difficult to classify. The 19th-century scholar William Michael Rossetti characterised him as a "glorious luminary", and "a man not forestalled by predecessors, nor to be classed with contemporaries, nor to be replaced by known or readily surmisable successors".
America a Prophecy is a 1793 prophetic book by the English poet and illustrator William Blake. It is engraved on eighteen plates, and survives in fourteen known copies. It is the first of Blake's Continental prophecies.
Jerusalem: The Emanation of the Giant Albion (1804–1820, with additions made even later) is a prophetic book by English poet William Blake. Jerusalem is the last, longest and greatest in scope of Blake's works. Etched in handwriting, accompanied by small sketches, marginal figures and huge full-plate illustrations, it has been described as "visionary theatre". The poet himself believed it was his masterpiece and it has been said that "of all Blake's illuminated epics, this is by far the most public and accessible". Nonetheless, only six copies were printed in Blake's lifetime and the book, like all of Blake's prophetic works, was all but ignored by his contemporaries.
The lyric to the famous hymn Jerusalem (text also by Blake, with music by Sir Hubert Parry) is not connected to this poem. It is in fact taken from the preface to another of Blake's "prophetic books", Milton.
