Guns with array of horizontal barrels and gun with three racks of barrels, circa 1481. Firearms in renaissance times were inaccurate and suffered from a slow rate of fire. Leonardo, in his design for a multi-barreled cannon of 1481, sought to overcome the slow rate of fire. The three racks of barrels allowed the re-loading of one rack while another was being fired and could maintained continuous fire power. The gun, with it's array of horizontal barrels, allowed for a wide scattering of shot.
