Wikipedia
A catapult is a device used to throw or hurl a projectile a great distance without the aid of explosive devices—particularly various types of ancient and medieval siege engines. Although the catapult has been used since ancient times, it has proven to be one of the most effective mechanisms during warfare. The word 'Catapult' comes from the two Greek words "kata" (downward) and "pultos" (a small circular battle shield).
