Catapults
Catapults were invented about 400 B.C. in the powerful Greek town called Syracus. These Greek engineers first constructed a small machine, called the Gastraphetes, sort of a crossbow. However, after they found out how good the smaller Gastraphetes were, they made a bigger one and put it on a carriage to transport it and added a windlass to cock the heavier machine. Some physical barriers prevented the Gastraphetes from getting any larger. So in the mid-forth century B.C. torsion springs were introduced, replacing the composite bow that was used in the Gastraphetes. The torsion spring consisted of a bundle of rope made from horsehair or sinew. This could get bigger and bigger as opposed to the Gastraphetes because they could just use more rope. The new catapults were now built with 2 torsion springs powering the catapult. Soon
Most catapults were mounted on a cart allowing movement but it wasn't always accurate. Many different catapults were created and the 3 that were most used were the Ballista, the Mangonel, and the Trebuchet. Other catapults were worse off because they were permanently mounted on a fortress and couldn't be moved and they were extremely heavy so if a stone ball hit the fortress wall then it stood a high chance of crumpling and the enemy would have an easy way in. Catapults were used in ancient and medieval warfare until the introduction of the gunpowder cannon in the 14th century. In this period another type of stone thrower was also developed, the Onager. The new catapult types remained in use until Late Antiquity. Trebuchets didn't rely on the energy of torsion it used the power of gravity and weight to help throw the object several hundred feet. A catapult could hurl large stones, spears, or other projectiles at an enemy but there was one main problem: a catapult is very hard to aim and once it has been aimed at the target the enemy has probably already moved, defeating the whole purpose of trying to aim a catapult. The earliest catapult was the Ballista and it resembled a cross bow and it shot arrows and small stones only. The catapult was a special type of siege engine, a large device used to attack a fortress or a large or small city. the Romans redesigned the torsion artillery, developing quite different new arrow shooting machines.
