Spanning the Renaissance to the 21st century, this collection shows how the notion of "shocking" art has evolved and explores why and how artists continue to push the public's visual buttons, whether in the form of a new technique, subject matter, or message. Dozens of works in large color reproductions are paired with an insightful text exploring the artist's intentions and the piece's historical context. While it's no great surprise to find here Marcel Duchamp, Damien Hirst, and Otto Dix, the real revelations are the artistic provocations of Caravaggio, Michelangelo, Chagall, Modigliani, Pollock, Turner, and Renoir.
