A catapult is a ballistic device used to launch 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 Latin 'catapulta', which in turn comes from the Greek Ancient Greek: καταπέλτης (katapeltēs), itself from (kata), "downwards" + πάλλω (pallō), "to toss, to hurl". Catapults were invented by the ancient Greeks.
The catapult and crossbow in Greece are closely intertwined. Primitive catapults were essentially “the product of relatively straightforward attempts to increase the range and penetrating power of missiles by strengthening the bow which propelled them”. The historian Diodorus Siculus (fl. 1st century BC), described the invention of a mechanical arrow-firing catapult (katapeltikon) by a Greek task force in 399 BC. The weapon was soon after employed against Motya (397 BC), a key Carthaginian stronghold in Sicily. Diodorus is assumed to have drawn his description from the highly rated history of Philistus, a contemporary of the events then. The introduction of crossbows however, can be dated further back: according to the inventor Hero of Alexandria (fl. 1st century AD), who referred to the now lost works of the 3rd-century BC engineer Ctesibius, this weapon was inspired by an earlier foot-held crossbow, called the gastraphetes, which could store more energy than the Greek bows. A detailed description of the gastraphetes, or the “belly-bow”, along with a watercolor drawing, is found in Heron's technical treatise Belopoeica.

Hybrid torsion catapult I made for a school project. Sorry about the wind noises but I can't really help that. This is one of the first shots we took, we were just guessing with the tension and angle of release. After some modifications I have it shooting close to 450 feet. Its a true thing of beauty. In this launch the melon went approximately 250 feet if I remember correctly.

I'd catapult downtown to see the galleries
And my favorite fiancee in a lavender gown
But I'm hooked up to a machine
It performs my daily functions through a tube in my wien
And today that thing malfunctioned
Like a forest fire it burnt a hole in me and I perspired
So there ain't gonna be a wedding
