Images dominate our lives. They tell us how to behave, even how to feel. They mould and define us. But why do these images, the pictures, symbols and the art we see around us every day, have such a powerful hold on us? The answer lies not here in our time but thousands of years ago. Because when our ancient ancestors first created the images that made sense of their world, they produced a visual legacy which has helped to shape our own. — Nigel Spivey, specialist in classical art and archaeology (6)
