Watch the Mona Lisa's argument

Vito Franco, professor of pathological anatomy at the University of Palermo (Italy) found evidence of a range of medical conditions affecting characters in some of the greatest works of the art world.

The Italian professor claims to be able to see signs of illness including osteoporosis and kidney stones.

Centuries passed, the Mona Lisa's enigmatic smile in Leonardo Da Vinci's painting haunted art lovers day and night wondering about the reasons behind her eyes. But little is known about the Mona Lisa's face as a result of the accumulation of fatty acids around the eye area, like those with high cholesterol, Professor Franco's opinion. He also noticed yellow fever and the accumulation of cholesterol under the skin in the area of ​​the Mona Lisa's left eye and fat fat on one hand.

Mr. Franco said: 'Artists have described it with art and tell us about the human trauma unconsciously. I look at art with a different eye from those who study art, like a mathematician listening to music in a different way to music critics'.

The man in Botticelli's "Young Portrait" may have Marfan syndrome.

Of the 100 studies, Franco discovered that two of the epitome of revival art appear to be rare Marfan syndrome - the disease that is torturing Osama Bin Laden.

The first is a young man wearing a red hat in Botticelli's "Young Portrait" and the other is a character in Parmigiano's "Madona with a long neck".

Both models have unusually long fingers and slender hands, which are symptoms of Marfan syndrome, hereditary connective tissue disorder syndrome.

Research on the image of pregnant Mary in Piero della Francesca's Madonna del Parto shows that Mary's neck is showing signs of goiter. The Spanish princess, Margarita, in Velazquez's Las Meninas may also suffer from the same disease.

The Spanish princess in Velazquez's Las Meninas shows signs of developing a disease of the neck.

And the artists themselves cannot avoid diseases. Raphael's 'school in Athens' picture depicts a sculptor Michelangelo appearing with a swollen knee due to kidney stones.

Franco said that the details "appear only the excess of uric acid typical of people with kidney stones", as a result of living off bread and wine while painting the Sistine Chapel.
