"Philippe Costamagna offers an intimate view of the art world’s most compelling figures—the connoisseurs who combine antenna-tingling intuition with encyclopedic erudition and immaculate visual recall. We also get a valuable and highly entertaining lesson in art history, deliciously spiced with gossip, anecdotes and art world politics."

Ross King, author of Brunelleschi’s Dome and Michelangelo and the Pope’s Ceiling
