"About Da Vinci Manuscript" Leonardo da Vinci takes notes every day of his life and writes in his own unique mirror image (from the bottom right corner of each page, from right to left, down and up), also Because his notes are for his own reference, the structure is scattered, the fonts are scribbled, and there are no punctuation. Although some speculations believe that Da Vinci is to keep secrets, the more reasonable view is that the image reversal is the nature of left-handed writing. Da Vinci's research in science and engineering is as memorable and outstanding as his art work. About 13,000 pages of notes and paintings in the manuscript are all records of mixed art and science. These records are from Da Vinci's journey through the observations and constant creations during the travel journey. Da Vinci manuscripts are divided into several categories: painting / sculpture / architecture / physiology / anatomy / zoology / astronomy / geography / philosophy / story / letter. These different forms of manuscripts were originally distributed in the hands of friends after his death, and are now mainly collected in museums, libraries or libraries around the world.
