The gladius is a short sword that was commonly used by the ancient Roman military. Typically measuring around 20 to 30 inches in length, it was designed for close combat, making it effective in battles and skirmishes. The blade was usually double-edged, allowing for both slashing and thrusting attacks. The gladius played a crucial role in the success of the Roman legions, contributing to their reputation as formidable fighters. Its design influenced many later swords, and it remains a symbol of Roman military prowess. The term "gladiator," referring to fighters in ancient Rome, is derived from this weapon.
