To regulate the trajectory of the projectiles and accelerate directing of the artillery, Leonardo invented various systems for aiming. This springald, which can be easily moved owing to its two large wheels, is equipped with a double-shaft tail that can spread out, providing multiple points for resting on the ground, thereby increasing stability.
The sighting and range for the shot can be regulated by the insertion of pegs, which fix the height of the wooden shaft on which the barrel is anchored. In his drawings, Leonardo also shows the springald’s defensive covering, called a mantlet, as well as special projectiles containing explosion chambers that can be filled with two different compositions of gunpowder.
