Leonardo da Vinci’s masterpiece once adorned Florence’s Palazzo Vecchio. However, at some point, it mysteriously vanished—perhaps painted over or deliberately concealed. Infrared scans hint at its survival beneath layers of frescoes, but excavating it poses risks. If it remains intact, uncovering it may rewrite Renaissance art history.
