It is held by the Biblioteca Ambrosianain in Milan, Italy. There are some 1,119 pages in this work spread over 12 volumes. This sketchbook contains some of Leonardo's most famous drawings and notes. = Of his interest are the pages on gliders and flying machines. Most of Leonardo's flying machines were designed after he studied birds. For this reason they generated their forward motion by mechanisms designed to flap the wings. In his notes he recorded the bird is an instrument functioning according to mathematical laws and man has the power to reproduce an instrument like this with all its movements. He built a working model of one of his flying machines and on January 2, 1496, he recorded in his notes that he was going to attempt to fly it the next day. It is unknown whether he didn't try or if the flight was a failure. Later on he did make a note to himself to try any more flying experiments over a lake where he would be less likely to be injured in a landing. Atlanticus also contains a design for a parachute which might have been conceived to allow for the safe escapeof any pilot from a flying device. One of his most famous patings was the mona lisa. it was made in 1530 it took 4 years to make. speculaters said there was two of them. In 1911 the mona lisa was stollen from Lourve. It was found and returand.
