The ballista, plural ballistae, sometimes called bolt thrower, was an ancient missile weapon that launched either bolts or stones at a distant target.

One talent ballista (26 kg [57 lb] weight projectile) was typical for Roman era ballista. The heaviest version ever made was built by Archimedes, and used stones up to three talents (78 kg [172 lb]).

A ranged weapon is any weapon that can engage targets beyond hand-to-hand distance, i.e. at distances greater than the physical reach of the user holding the weapon itself. The act of using such a weapon is also known as shooting. It is sometimes also called projectile weapon or missile weapon because it typically works by launching solid projectiles ("missiles"), though technically a fluid-projector and a directed-energy weapon are also ranged weapons. In contrast, a weapon intended to be used in hand-to-hand combat is called a melee weapon.
