Archimedes is the Greek scientist who discovered the principle of the lever and invented the double pulley. He did not invent the catapult but he did improve it. He also discovered the when an object is place in fluid, the volume of the fluid that is displaced is equal to the volume of the object.
The catapult is a simple machine. The work input is the restraining of the payload and pressure put on the spring or lever. The work output is the delivery of the payload with the energy of the work transferred to it.
