Etymology

The word 'catapult' comes from the Latin 'catapulta', which in turn comes from the Greek Ancient Greek: καταπέλτης (katapeltēs), itself from κατά (kata), "downwards" and πάλλω (pallō), "to toss, to hurl". Catapults were invented by the ancient Greeks and in ancient India where they were used by the Magadhan Emperor Ajatashatru around the early to mid 5th century BC.
