Rapid Fire Crossbow
Leonardo's crossbow designs are a series of shooting weapon schematics designed by Leonardo da Vinci that are in the '' Codex Atlanticus.'' One version, a self-spanning infantry weapon called the ''Rapid Fire Crossbow'' (''Balestra Veloce'' in Italian), is found on sheets 143r, 153r, and 155r. The other is the ''Giant Crossbow'' (''Balestra Gigante'' in Italian) design intended to be a mounted siege weapon found on sheet 149a in the Codex. The creation of the large design is linked to Ludovico Sforza, an Italian prince in the Renaissance era. Given the constant warfare in the Italian peninsula at the time, he wanted to expand and advance both his military and the territory he governed in the Milan region. To do so, he wanted to update the contemporary treatise on military engineering by Roberto Valturio. Leonardo responded by writing Sforza a letter that included a number of innovative machine designs with one of them being the ''Giant Crossbow.'' Leonardo also highlighted in ...

Science And Inventions Of Leonardo Da Vinci
Leonardo da Vinci (1452–1519) was an Italian polymath, regarded as the epitome of the "Renaissance Man", displaying skills in numerous diverse areas of study. While most famous for his paintings such as the ''Mona Lisa'' and the ''Last Supper'', Leonardo is also renowned in the fields of civil engineering, chemistry, geology, geometry, hydrodynamics, mathematics, mechanical engineering, optics, physics, pyrotechnics, and zoology. While the full extent of his scientific studies has only become recognized in the last 150 years, during his lifetime he was employed for his engineering and skill of invention. Many of his designs, such as the movable dikes to protect Venice from invasion, proved too costly or impractical. Some of his smaller inventions entered the world of manufacturing unheralded. As an engineer, Leonardo conceived ideas vastly ahead of his own time, conceptually inventing the parachute, the helicopter, an armored fighting vehicle, the use of concentrated solar power, ...

Repeating Crossbow
The repeating crossbow (), also known as the repeater crossbow, and the Zhuge crossbow (, also romanized Chu-ko-nu) due to its association with the Three Kingdoms-era strategist Zhuge Liang (181–234 AD), is a crossbow invented during the Warring States period in China that combined the bow spanning, bolt placing, and shooting actions into one motion. The earliest archaeological evidence of the repeating crossbow is found in the state of Chu, but it uses a pistol grip that is different from the later and more commonly known Ming dynasty design. Although the repeating crossbow was in use throughout most of Chinese history until the late Qing dynasty, it was generally regarded as a non-military weapon suited for women, defending households against robbers.

Polybolos
The polybolos (the name means "multi-thrower" in Greek) was an ancient Greek repeating ballista, reputedly invented by Dionysius of Alexandria (a 3rd-century BC Greek engineer at the Rhodes arsenal,) and used in antiquity. The polybolos was not a crossbow since it used a torsion mechanism, drawing its power from twisted sinew-bundles. However the earlier and similar oxybeles employed a tension crosbow mechanism, before it was abandoned in favor of torsion. Philo of Byzantium ( 280 BC – 220 BC) encountered and described a weapon similar to the polybolos, a catapult that could fire again and again without a need for manual reloading. Philo left a detailed description of the gears that powered its chain drive (the oldest known application of such a mechanism) and that placed bolt after bolt into its firing slot. Design The polybolos would have differed from an ordinary ballista in that it had a wooden hopper magazine, capable of holding several dozen bolts, that was positi ...

Lever Action
The toggle-link action used in the iconic Winchester Model 1873 rifle, one of the most famous lever-action firearms Picture showing a Volcanic Pistol A lever action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area (often incorporating it) that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, fully automatic, and/or burst mode actions. A firearm using this operating mechanism is colloquially referred to as a levergun. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have been made. The Winchester Model 1873 rifle is one of the most famous lever-action firearms, but many manufacturers (notably Henry Repeating Arms and Marlin Firearms) also p ...

It was built in the same area of the ancient Roman fortification of ''Castrum Portae Jovis'', which served as '' castra pretoria'' when the city was the capital of the Roman Empire. It was enlarged by Galeazzo's successors, Gian Galeazzo, Giovanni Maria and Filippo Maria Visconti, until it became a square-plan castle wit ...
