In this week's books podcast, I'm joined by the sculptor Antony Gormley and the art critic Martin Gayford to talk about their new book Shaping The World: Sculpture from Prehistory to Now. They talk about the special place sculpture occupies in the arts, the lines of connection between its ancient origins and the avant-garde, and their views on the new fashion for tearing down statues. Plus, Antony talks about his own work from Field to the Angel of the North — and why he and Martin can't see eye-to-eye on the Baroque.
