Leonardo Da Vinci : - Lot 26

Leonardo Da Vinci : Limited numbered series of 3,000 fountain pens (number 2733) in silver-plated and anodized aluminum with platinum-plated appointments. Leonardo da Vinci: the universal genius. This indefatigable Renaissance artist and researcher (1452-1519) left behind not only his famous paintings, such as The Mona Lisa and The Last Supper, but also 10,000 manuscript sheets covered with scientific sketches and drawings that bear witness to his second great passion: research and meticulous exploration of the world around him. For almost 30 years, Leonardo tried to understand how a living creature could take flight by gaining momentum, and analyzed the aerodynamic behavior of bird and bat wings. The innumerable individual drawings and his independent treatise on bird flight represent the beginnings of the development of his spectacular flying machines. The engraving on the fountain pen section shows a study of a wing; the engraving of a bat on the nib comes from one of the drawings in Leonardo's treatise on bird flight. Leonardo also devoted himself to engineering. He was constantly developing new ways of transmitting force by means of cogwheels, which are still in use today. In reference to the countless sketches in which Leonardo depicted the cogwheels for his revolutionary technical innovations, the limited series clip is adorned with a small red gold cogwheel with a rotating mechanism. Leonardo intended most of his technical inventions to work with mechanical gears. In this context, he was always confronted with the problem of stability and material combinations. For his toothed gears, whose components had to be particularly secure, he used bevel adapters to combine different materials. The platinum finish of the body and cap are inspired by these bevel adapters. The cone also takes the form of a wheel with small, lamellar teeth, paying homage to Leonardo da Vinci's many inventions of gear-driven machines. Leonardo da Vinci was ambidextrous and wrote in several directions, though mostly from right to left, using mirror writing, seen at the time as a kind of secret language that enabled him to protect his inventions. But Leonardo was also interested in the notion of reflection in his scientific research: his most innovative invention was his conception of concave mirrors, which he wanted to use to reflect the sun and thus heat water. A small mirror embedded in the cap's head pays tribute to this invention. Looking through the openings at the top of the cap, it is possible to discover the Montblanc emblem, reflected by the latter. Equipped with a medium-sized rhodium-plated 18-carat gold nib, piston filling system. In its wooden box with papers and over-box.
