Drawing of a Roman ballista

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.[1] 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).[2] Katapultos was then taken to mean "shield piercer".



Greek and Roman catapults

Ancient mechanical artillery: Catapults (standing), the chain drive of Polybolos (bottom center), Gastraphetes (on wall)

The date of the introduction of crossbows, however, can be dated further back: According to the inventor Hero of Alexandria (fl. 1st c. 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 (belly shooter), which could store more energy than the Greek bows. A detailed description of the gastraphetes, along with a watercolor drawing, is found in Heron's technical treatise Belopoeica.[3][4]

Roman 'catapult-nest' in the Dacian Wars

A third Greek author, Biton (fl. 2nd c. BCE), whose reliability has been positively reevaluated by recent scholarship,[5][6] described two advanced forms of the gastraphetes, which he credits to Zopyros, an engineer from southern Italy. Zopyrus has been plausibly equated with a Pythagorean of that name who seems to have flourished in the late 5th century BC.[7][8] He probably designed his bow-machines on the occasion of the sieges of Cumae and Milet between 421 BC and 401 BC.[9][10] The bows of these machines already featured a winched pull back system and could apparently throw two missile at once.[11]

From the mid-fourth century BC onwards, evidence of the Greek use of arrow-shooting machines becomes more dense and varied: Arrow firing machines (katapaltai) are briefly mentioned by Aeneas Tacticus in his treatise on siegecraft written around 350 BC.[11] An extant inscription from the Athenian arsenal, dated between 338 and 326 BC, lists a number of stored catapults with shooting bolts of varying size and springs of sinews.[12] The later entry is particularly noteworthy as it constitutes the first clear evidence for the switch to torsion catapults which are more powerful than the flexible crossbows and came to dominate Greek and Roman artillery design thereafter.[11] Another Athenian inventory from 330-329 BC includes catapults bolts with heads and flights.[12] Arrow firing machines in action are reported from Philip II's siege of Perinth (Thrace) in 340 BC.[13] At the same time, Greek fortifications began to feature high towers with shuttered windows in the top, which could have been used to house anti-personnel arrow shooters, as in Aigosthena.[14] In Roman times machine known as an arcuballista was probably similar to the crossbow.[15] Alexander the Great introduced the idea of using them to provide cover on the battlefield in addition to using them during sieges. Projectiles included both arrows and (later) stones.

The Romans started to use catapults probably as arms for their wars against Syracuse, Macedon, Sparta and Aetolia (3rd–2nd century BC). Later the Romans used ballista catapults on their warships.

Medieval catapults

Castles and fortified walled cities were common during this period - and catapults were used as a key siege weapon against them. As well as attempting to breach the walls, incendiary missiles could be thrown inside—or early biological warfare attempted with diseased carcasses or putrid garbage catapulted over the walls.

Designs include the torsion-powered mangonel, onager and ballista, and the gravity-powered trebuchet.

Catapults were gradually replaced by the cannon in the 14th century.

Later Use

French troops using a catapult to throw hand grenades during World War I

The last large scale military use of catapults was during the trench warfare of World War I. During the early stages of the war, catapults were used to throw hand grenades across no man's land into enemy trenches. These were eventually replaced by small mortars.

Special variants called aircraft catapults are used to launch planes from land bases and sea carriers when the takeoff runway is too short for a powered takeoff or simply impractical to extend. Ships also use them to launch torpedoes and deploy bombs against submarines. Small catapults, referred to as traps are still widely used to launch Clay targets into the air in the sport of Clay pigeon shooting.

Until recently, catapults were used by thrill-seekers to experience being catapulted through the air. The practice has been discontinued due to fatalities, when the participants failed to land onto the safety net.[citation needed]


A commercial model of a Greek and Roman Ballista

Catapults of all types and sizes are being built for school science and history fairs, competitions or as a hobby. Catapult projects can inspire students to study different subjects including physics, engineering, science, math and history. These kits can be purchased from Renaissance Fairs, or from several online stores, and the three types of catapults are ballista, trebuchet, and Mangonel.

Simple English

A catapult is a type of machine used as a weapon to shoot rocks or other things that would cause damage to something else. Catapults use weights and levers to send the rocks or other things into the air. They are simpler than other modern weapons and not useful in modern warfare. Catapults were common in the past, especially the Middle Ages. Nowadays catapults are used to study old weapons or try using them for experience.

Sometimes, instead of rocks, pitch or hot tar would be thrown to set the target on fire.

Often catapults were set on higher ground or on castle towers to let them shoot farther. They were also used to shoot rocks to break castle walls.
