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 Latin 'catapulta', which in turn comes from the Greek καταπέλτης, itself from, "downwards" + πάλλω, "to toss, to hurl". Catapults were invented by the ancient Greeks.
