In the French city of Nantes, a coded manuscript (photo, from bbcimg.co.uk) by Leonardo da Vinci has been discovered in a public library, after a journalist came across a reference to it in a Leonardo biography, the library said.
The coded manuscripts was among 5,000 others which were donated by wealthy collector Pierre-Antoine Labouchere in 1872 and then forgotten.
Written from right to left in Leonardo’s trademark mirror-writing, the text has not been deciphered yet.
“He was most probably writing in 15th-century Italian, and possibly in other languages,” the head of the Nantes library, Agnes Marcetteau said.
In 2008 another rare item was uncovered in the Labouchere collection : a score by composer Wolfgang Amadeus Mozart.
Leonardo da Vinci (1452-1519) was one of the most important artists and scientists of the Renaissance.
His most famous masterpiece, the Mona Lisa painting is in the Louvre museum, in Paris. But Leonardo da Vinci also designed the prototype for a flying machine with a rotating wing similar to today’s helicopters.
