Miss Glori said: 'From my research I have identified the subject as Bianca Giovanna Sforza and the bridge in the background is the one that spanned the River Trebbia at Bobbio. 'Five hundred years ago Bobbio was an important centre of culture famous for its library and it was also on a major crossroad with a castle in the centre.
'It's highly likely that Da Vinci visited Bobbio because of its famous library and that he painted the picture from memory a few years later, probably when he was living in France. 'Obviously over the centuries the lie of the land has changed but the serpent style road you can see in the background of the Mona Lisa is still visible at Bobbio.'
She added that the structure of the arched bridge, which has been rebuilt, was similar to the one that crossed the River Trebbia and which was washed away in 1472 - the last two numbers being painted faintly into the bridge.
Locals in Bobbio are also convinced the bridge is the same one pointing to the numerous uneven arches in the present day structure and the one in the painting. The valley where Bobbio lies was described by Ernest Hemingway as the most beautiful in the world and the town's bridge is also known as the Devil's Bridge. Legend has it that it was built by the Devil in one night after he made a pact with Saint Columbanus who promised him the soul of the first passerby but when the bridge was finished the Irish Saint sent a dog over. But retired Oxford University professor Martin Kemp - a Da Vinci expert - is not convinced by Miss Glori's theory.
'The portrait is almost certainly of [Italian noblewoman] Lisa del Giocondo however unromantic and un-mysterious that idea might be,' he said.
'There have been many attempts to identify the landscape as a specific location and I do not find the resemblance to the Bobbio bridge all that close.
'I have great reservations about all attempts to find some obscurely hidden meaning in Renaissance works of art.'
