Look Again is a new series of short books from Tate Publishing, opening up the conversation about British art over the last 500 years, and exploring what art has to tell us about our lives today. Written by leading voices from the worlds of literature, art and culture, each book sheds new light on some of the most well-known, best-loved and thought-provoking artworks in the national collection, and asks us to look again. Author Philip Hoare takes us on an exploration of the sea and looks at its power and alluring draw for centuries of artists featured in the Tate collection, from William Blake to Maggi Hambling.
