Stealing the Mystic Lamb: The True Story of the World's Most Coveted Masterpiece is a non-fiction book by art historian Noah Charney. The book was published in 2010 by PublicAffairs. It tells the story of The Ghent Altarpiece (also known as The Adoration of the Mystic Lamb, or simply The Mystic Lamb), a monumental oil painting by the Flemish master Jan van Eyck, currently on display in the cathedral of Saint Bavo, in the city of Ghent. The work is arguably the most influential painting in history, and it is also the most frequently stolen artwork of all-time. Charney's book tells the story of the artwork and the many crimes and mysteries of which it was the victim since its completion in 1432.
