William Blake was an English poet, painter, and printmaker. Largely unrecognised during his lifetime, Blake is now considered a seminal figure in the history of the poetry and visual arts 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". His visual artistry led 21st-century critic Jonathan Jones to proclaim him "far and away the greatest artist Britain has ever produced". In 2002, Blake was placed at number 38 in the BBC's poll of the 100 Greatest Britons. Although he lived in London his entire life, he produced a diverse and symbolically rich œuvre, 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 is held in high regard by later critics 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".
