William Blake (1757 - 1827) is one of the great figures in literature, by turns poet, artist and visonary. Profoundly libertarian in outlook, Blake's engagement with the issues of his day is well known and this - along with his own idiosynratic concerns - flows through his poetry and art. Like Milton before him, the prodigality of his allusions and references is little short of astonishing. Consquently, his longer viosnary poems can challege the modern reader, who will find in this avowedly open edition all they might need to interpret the poetry.
