The Mona Lisa Was Reexamined With New Technology — Experts Were Shocked

The Mona Lisa was reexamined with new technology, and what the experts found has rewritten five centuries of art history in ways the headlines never fully told you. The painting hanging behind bulletproof glass in the Louvre is not a portrait. It is a sealed laboratory. Inside its thin layers of oil on poplar wood sits a hidden chemical recipe Leonardo never wrote down, sixteen years of buried decisions no human eye has ever seen, and an engineered optical system five centuries old that nobody knew existed until a French scientist pointed a thirteen-wavelength camera at it one night in 2004.
