Renaissance humanism recognized no mutually exclusive polarities between the sciences and the arts, and Leonardo's studies in science and engineering are as impressive and innovative as his artistic work.These studies were recorded in 13,000 pages of notes and drawings, which fuse art and natural philosophy (the forerunner of modern science), made and maintained daily throughout Leonardo's life and travels, as he made continual observations of the world around him.
Leonardo's writings are mostly in mirror-image cursive. The reason may have been more a practical expediency than for reasons of secrecy as is often suggested. Since Leonardo wrote with his left hand, it is probable that it was easier for him to write from right to left.
Leonardo's notes appear to have been intended for publication because many of the sheets have a form and order that would facilitate this. In many cases a single topic, for example, the heart or the human fetus, is covered in detail in both words and pictures on a single sheet.
Why they were not published within Leonardo's lifetime is unknown.

I agree with your point of view,he is too excellent to be understood by his time.There is a saying in China:木秀于林，风必摧之.There was many men had the same situation with him,like Van Gogh,Nietzsche and so on.But we will find:Time can not stop the excellent person in human.
