"America a Prophecy" is a 1793 prophetic book by 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. America was one of the few works that Blake describes as "illuminated printing", those of which were either hand coloured or colour printed with the ink being placed on the copperplate before printed. Early sketches for America were also included in his notebook, which Blake used between 1790 and 1793. William Blake (1757 1827) was a British poet, painter, visionary mystic, and engraver, who illustrated and printed his own books. Blake proclaimed the supremacy of the imagination over the rationalism and materialism of the 18th-century. Largely unrecognised during his lifetime, Blake is now considered a seminal figure in the history of both the poetry and visual arts of the Romantic Age.
