A book full of surprises, discoveries, forgotten treasures and lost tales, The Secrets of Art takes us on a journey through the art world's mysteries to reveal that works of art are not always what they seem.

A long-lost medieval masterpiece unearthed in the Tower of London. A secret message that only an elite few can read encoded in a painting. A glimpse of a ghostly image beneath the surface of a portrait. The intriguing stories of these works, and many more, are brought to life by author, historian and art detective Debra N. Mancoff, as she reveals secret symbols used by Leonardo da Vinci, Vermeer and Caravaggio, uncovers layers of meaning in paintings by Van Gogh, Picasso and Dali, and provides insight into works by Frida Kahlo, Kara Walker and Marina Abramovic.

Drawing upon the findings of advanced technology, new research, scientific analysis and old-fashioned curiosity, The Secrets of Art unveils the layers of meaning beneath the surfaces of great works of art in a collection of tales that are fully based in fact but are as fascinating as fiction.
