The ''monagon'' V- spring catapult
It was a powerful stone-throwing catapult that was first used by the Macedonian army of Philip II. It consisted of a powerful wooden frame and one long joist whose utmost end was supported by a torsion spring, the "neura" and the other utmost end had a leather belt where the launch stone was placed. The torsion springs were comprised of twisted ropes from animal sinews or women's hair. The joist was cocked with a rope wound around an axle which was turned with the help of handspikes and its rapid release was achieved with the help of a special claw.
