Leonardo worked on several designs for cannons capable of simultaneously shooting multiple projectiles. These weapons were decidedly avant-garde for their time, and likely to trigger the interest of potential commissioners.
This multiple-shot firearm has ten small-caliber guns mounted on a single gun carriage. Equipped with two wheels for easy movement about the battlefield, it can aim at multiple targets. The arrangement of the firearm barrels into fan array makes it possible to increase the firing volume, thereby reducing the effects of inaccuracy in shooting. The projectiles are loaded through a small hatch located at the center of the gun array. A crank is used to adjust the inclination of the instrument, making it possible to regulate the launch trajectory.
