The bicycle of Leonardo da Vinci
"During the restoration of the "Atlantic Code" Leonardo da Vinci "made by the monks of Grottaferrata (Rome) in 1966, came to light, along with other drawings, the sketch of the" bicycle "made with a charcoal pencil light brown tint.
Professor Marinoni attributed the drawing, remained invisible for more than three hundred and sixty as in the sixteenth century had been pasted to another sheet by Pompeo Leoni, clearly not by Leonardo, with a copy of a lost Master drawing badly done by a pupil of Leonardo's workshop. The author of the design had to be the "small", the model student and the teacher said Salai, which is the only written word on the page. The chain drive with wheels cubic teeth certainly comes from Leonardo's drawing of the Museum of Madrid, F.10, that no one could know before 1966. The opinion of Professor Marinoni was shared by several scholars, but still remains controversial."
