Mona Lisa doubts allayed
New tests on a painting billed as the original version of the Mona Lisa, Leonardo da Vinci's 15th-century portrait, have produced fresh proof that it was the work of the Italian master, a Swiss-based art foundation said .
The tests, one by a specialist in "sacred geometry" and the other by the Swiss Federal Institute of Technology in Zurich, were carried out in the wake of the Geneva unveiling of the painting, the Isleworth Mona Lisa, in September.
"When we add these new findings to the wealth of scientific and physical studies we already had, I believe anyone will find the evidence of a Leonardo attribution overwhelming," said David Feldman, vice-president of the foundation.
The Mona Lisa in the Paris Louvre for over three centuries has long been regarded as the only one painted by Leonardo, although there have been copies.
Claims for the Swiss-held one were dismissed by some experts last year.
