The Mona Lisa has yet another mystery.
Utilizing X-rays to analyze the chemical composition of a small fragment from this famous masterpiece, researchers have uncovered novel insights into the artistic methods Leonardo da Vinci used when creating the Mona Lisa.
Mona Lisa is a painting portrait of a woman with a deeply enigmatic smile.
Is there a mystery behind the Mona Lisa?
Meanwhile, the identity of the Mona Lisa herself became mythologized. Often thought to be Lisa del Giocondo, the wife of a wealthy Florentine merchant, the lack of commission from her husband has raised doubts about the model’s identity.
Some have romanticized her as a mysterious seductress.
Leonardo da Vinci loved to experiment, and each of his paintings was completely different technically.
X-RAYS.

X-ray radiation is a high-energy electromagnetic radiation.
In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895 and named it X-radiation, an unknown type of radiation.
This image is of a patient who was examined with a thoracic fluoroscope in 1940.
It was used to show that radiation exposure during the X-ray procedure would be negligible.

These are X-RAY images by James Green, from “Sciagraphs of British Batrachians and Reptiles” (1897).
