The Last Supper Just Got AI Analysis — What's Hidden in the Paint Changes Everything

Leonardo da Vinci painted The Last Supper between 1495 and 1498. For five centuries, overpainting obscured what was underneath. In 1999, conservator Pinin Brambilla Barcilon completed a 21-year restoration that revealed only 20% of Leonardo's original paint survived. In 2007, musician Giovanni Maria Pala discovered that the bread loaves and hand positions form a 40-second musical composition when read as a staff. Slavisa Pesci's mirror overlay revealed hidden figures and a chalice between Christ's hands. Leonardo wrote in mirror script. He encoded his notebooks. The question is what else he encoded in the most analyzed painting in Western art.
