Summary
Terahertz time-domain imaging has revealed the internal structure of Leonardo da Vinci's 'The Last Supper,' providing new insights into the wall painting's composition. This non-invasive technique confirmed earlier estimates based on fragment samples, offering a deeper understanding of the artwork's layered complexity without requiring physical intervention. The study leveraged terahertz waves to penetrate the painting and map its internal layers, supporting conservation efforts by validating prior hypotheses about its structure.
