For those who don't know of William Blake, he was a poet, painter, engraver, visionary ( literally - he saw angels at the bottom of his garden ), and religious iconoclast. And for an eighteenth-century Englishman his politics were amazingly progressive: he spoke out in favour of equality of the sexes, he opposed slavery and, although religious, he attacked organised religion ie the Church Of England. He also supported the French and American revolutions, a dangerous stance at the time.
I read Blake's Songs Of Innocence And Of Experience at A-Level, and his work made a lasting impression on me. His was a unique talent which, as usual, was barely appreciated in his own lifetime.
