LEONARDO, THE INVENTOR
While he is most famously known for his works of art like the Mona Lisa, The Last Supper and The Vitruvian Man, Leonardo’s studies in science and engineering are sometimes considered as impressive and innovative. These studies were recorded in 13,000 pages of notes and drawings, which fuse art and natural philosophy (the forerunner of modern science). They were made and maintained daily throughout Leonardo’s life and travels, as he made continual observations of the world around him
Leonardo’s notes and drawings display an enormous range of interests and preoccupations, some as mundane as lists of groceries and people who owed him money and some as intriguing as designs for wings and shoes for walking on water. There are compositions for paintings, studies of details and drapery, studies of faces and emotions, of animals, babies, dissections, plant studies, rock formations, whirlpools, war machines, flying machines and architecture.
These notebooks—originally loose papers of different types and sizes, distributed by friends after his death—have found their way into major collections. Most of Leonardo’s writings are in mirror-image cursive. Since Leonardo wrote with his left hand, it was probably 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 during Leonardo’s lifetime is unknown.
Leonardo was fascinated by the phenomenon of flight for much of his life, producing many studies, including Codex on the Flight of Birds (c. 1505), as well as plans for several flying machines such as a flapping ornithopter and a machine with a helical rotor. The British television station Channel Four commissioned a 2003 documentary, Leonardo’s Dream Machines, in which various designs by Leonardo, such as a parachute and a giant crossbow, were interpreted, constructed and tested. Some of those designs proved successful, whilst others fared less well when practically tested. Source: Wikipedia
