In 1973, Derek Jarman set off from London to film the stones of Avebury. He was following in the footsteps of Paul Nash, who had photographed the ancient megaliths a generation before. Standing in that muddy field, by those stones, both artists had felt a direct connection to their hero - a man who had died a long, long time ago, yet who remained electrically alive to them. In this alluring and poetic odyssey, Philip Hoare traces the enduring legacy of William Blake and how he came to inspire so many creative lives. Reaching out of his past and into our future, Blake draws together the natural world and metaphysical realms, merging the human and the animal and the spiritual, firing up twentieth-century artists, filmmakers, poets, writers and musicians with his radical promise of absolute freedom. This stirring, deeply felt book brings us back to Blake and shows that art still has the power to create positive change. PHILIP HOARE is the author of ten books, including _Leviathan, or the Whale_, winner of the Baillie Gifford Prize for Non-Fiction. He lives on the south coast of England and swims every day in the sea.
