Going beyond the Who, When, and Where of great art to address the all-important Why, this remarkable series firmly sets each of ten of the world's greatest masterpieces within the vibrant context of its times. A good deal of How is included as well, as X-ray analysis and 3-D reconstructions expand on the narratives--and solve long-unexplained riddles--by revealing details that could not otherwise be seen. And behind it all is valuable commentary by leading art historians, artists, art critics.
