Arbalest vs. Ballista — What's the Difference?
Edited by Tayyaba Rehman — By Maham Liaqat — Updated on April 15, 2024
An arbalest is a late medieval crossbow with a powerful mechanism, used for precise, short-range shots, while a ballista is an ancient siege engine designed for launching projectiles over long distances.

Key Differences
The arbalest, developed in the 12th century, features a robust and heavy construction, employing a metal prod (the bow part) which allows for greater force and thus increased penetration of armor. In contrast, the ballista, which predates the arbalest by centuries, originated in ancient Greece and Rome, functioning more like a giant crossbow, primarily utilized in siege warfare to hurl large bolts or stones.
While the arbalest is operated by an individual, typically a skilled crossbowman, the ballista requires a team to load, aim, and discharge due to its larger size and mechanical complexity. This makes the arbalest more suitable for mobile and responsive combat situations, whereas the ballista is more static, used for strategic positions during sieges.
The mechanism of an arbalest includes a windlass or cranequin to draw the string, a process requiring significant strength and time, highlighting its use for powerful, deliberate shots. On the other hand, the ballista uses torsion power, with twisted skeins usually made of sinew, hair, or animal gut, to propel projectiles, which allows for greater range and force, suitable for breaching fortifications or formations.
In terms of projectiles, the arbalest fires bolts, which are shorter and heavier than typical arrows, designed for armor penetration. The ballista, however, can launch a variety of ammunition, including bolts, stones, and even incendiary materials, adapted to diverse siege needs.
While the arbalest is largely seen as a weapon of personal armament in medieval armies, the ballista serves as an engineering marvel of ancient warfare, illustrating early developments in mechanical artillery. Both represent significant advancements in military technology for their respective eras.

Ballista
Used in sieges to damage fortifications or target large troop formations.
The ballista’s bolts crashed into the enemy ranks, causing chaos and disarray.
Arbalest
The arbalest (also arblast) was a late variation of the crossbow coming into use in Europe during the 12th century. A large weapon, the arbalest had a steel prod ("bow").
Ballista
The ballista (Latin, from Greek βαλλίστρα ballistra and that from βάλλω ballō, "throw"), plural ballistae, sometimes called bolt thrower, was an ancient missile weapon that launched either bolts or stones at a distant target. Developed from earlier Greek weapons, it relied upon different mechanics, using two levers with torsion springs instead of a tension prod (the bow part of a modern crossbow).
