Historians learn a great deal from historical texts -- and not only that which was written, but that which was unwritten. Join Robert and Christian as they explore the world of palimpsests, the erased books just under the surface of ancient tomes. Modern technology allows us to uncover more and more of their secrets, while the idea of the palimpsest itself serves as a powerful metaphor for media, the mind and maybe life itself.
