"So one must write about art and the past," says Florian Illies about Laura Cumming's masterfully written literary biography "The Lost Velázquez: A Obsessed Collector, a Missing Painting, and the Greatest Painter of All Time." Velázquez is considered the greatest painter of all time. However, we know very little about his life so far. Through the peculiar story of his most passionate admirer, the Victorian bookseller John Snare, art critic Laura Cumming uncovers astonishing details about the great Spanish master in her gripping dual biography. At an auction, John Snare buys a dusty portrait of a prince and spends the rest of his life trying to prove that the painting is an authentic Velázquez. Obsessed, he pursues the mystery surrounding the artwork's origin.
