He was the ultimate Renaissance man - studying anatomy, designing a rudimentary helicopter and creating some of the most admired paintings of the age.
But could Leonardo da Vinci also have perpetrated history’s greatest art forgery?
That’s the suggestion of one expert, who claims that Leonardo was responsible for faking the Turin Shroud.
The relic has inspired generations of pilgrims who have flocked to see what they believe is the face of the crucified Jesus.
But it has also provoked bitter controversy after scientists carbon-dated it to the Middle Ages.
Now an American artist has entered the fray, putting forward her own theory about its origin.
Lillian Schwartz, a graphic consultant at the School of Visual Arts in New York, claims that the image is a self-portrait of Leonardo, which was made using a crude photographic technique.
Italian scientists says Holy Shroud dating inaccurate
From May 26th 2009. In 1988, carbon-14 tests concluded that the Shroud of Turin, the piece of cloth widely regarded by history as having wrapped the body of Jesus after his death, was a fake fabricated around the year 1260.
Italian scientists, however, are now debunking that this idea, claiming that the dating test did not work and that the laboratory hid errors.
Vatican insider Marco Tossati has repeated vital calculations and says that the original test was not valid.
