Book excerpt: The "Mona Lisa" is widely recognized as the most famous painting in the history of art--and an undeniable icon of pop culture. Her celebrated face is used to sell everything from champagne to automobiles, and appears on ashtrays, mouse pads, and refrigerator magnets. More than any other art object, the "Mona Lisa "demonstrates that something can be high art and pop, classic and cool. Likewise, Donald Sassoon's elegant narrative is as much the story of one painting's ascendance to the status of global icon as it is the popularization of serious and distinguished art. A professor and acclaimed writer, Sassoon provides a fascinating account of Leonardo da Vinci, the Renaissance genius who created the picture; who the mysterious subject was; why it gained its unrivalled position in the art world; and how it has come to be used and abused by other artists and the international advertising industry. Lavishly illustrated, "Becoming Mona Lisa" is at once social, cultural, and art history of the highest order.
