What makes Blake's poetry so innovative are his engravings.
William Blake was an English poet, painter, and printmaker who is now considered a seminal figure in the history of the poetry and visual arts of the Romantic Age. Besides, he was also an engraver, so his work needed to be seen from three angles to be fully understood.
Now, he is considered to be a true pioneer and visionary, however, in his own lifetime he was largely unrecognised.
