Da Vinci invented the manuscript - heavy hammer thrower

Product Description

https://www.youtube.com/watch?v=milHLWHUkRw&feature=youtu.be Although the catapult was a common siege weapon of the Middle Ages, Da Vinci's design was the most powerful and unique at the time - he used a single master mast! According to the drawing on the Da Vinci Atlantic Codote, this was a catapult designed for the Dukes of Milan in 1482, which allowed the Duke to leave a deep impression on Da Vinci, who was a military engineer. Use the included clay ball to fire up to six meters maximum! Let the historical invention in the modern reborn DIY model, play the best effect of entertaining. "About Da Vinci Manuscripts" Leonardo da Vinci took notes every day for the rest of his life and wrote it in his own unique mirror image (starting from the bottom right corner of each page, from right to left, and writing up and down). Because his notes are for his own reference only, the structure is scattered, the fonts are scribbled, and there are no punctuation marks. Although some speculated that Da Vinci was in order to keep secrets, a more plausible view was that mirroring and writing was only a matter of left-handed writing. Da Vinci's research in science and engineering is as impressive as his artwork. About 13,000 pages of notes and paintings in the manuscript are all made up of records of mixed arts and sciences. These records come from Da Vinci's observations and his constant creation during his travels. Da Vinci manuscripts are divided into several categories: painting/engraving/architectural/physiological/anatomical/zoological/astronomy/geography/philosophy/story/letter. These manuscripts of different sizes were originally distributed in the hands of friends after his death. They are now mainly collected in museums, library rooms or libraries around the world.
