Gladius

Name

Gladius is a Latin masculine second declension noun. Its (nominative and vocative) plural is gladiī. However, gladius in Latin refers to any sword, not specifically the modern definition of a gladius. The word appears in literature as early as the plays of Plautus (Casina, Rudens).

Modern English words derived from gladius include gladiator ("swordsman") and gladiolus ("little sword", from the diminutive form of gladius), a flowering plant with sword-shaped leaves.

Predecessors and origins

Livy relates the story of Titus Manlius Torquatus accepting a challenge to a single combat by a large Gallic soldier at a bridge over the Anio river, where the Gauls and the Romans were encamped on opposite sides of the river. Manlius strapped on the Hispanic sword (Gladius Hispanus). During the combat he thrust twice with it under the shield of the Gaul, dealing fatal blows to the abdomen. He then removed the Gaul's torc and placed it around his own neck, hence the name, torquatus.

The combat occurred during the consulships of C. Sulpicius Peticus and C. Licinius Stolo—i.e., about 361 BC, long before the Punic Wars, but during the frontier wars with the Gauls (366-341 BC). One theory proposes the borrowing of the word gladius from *kladi- during this period, relying on the principle that k often became g in Latin. Ennius attests the word. Gladius may have replaced ensis, which in the literary periods was used mainly by poets.

The exact origin of the gladius Hispanus is disputed. While it is likely that it descended ultimately from Celtic swords of the La Tene and Hallstat periods, no one knows if it descended directly from Celtiberian troops of the Punic Wars, or through Gallic troops of the Gallic Wars.

Arguments for the Celtiberian source of the weapon have been reinforced in recent decades by discovery of early Roman gladii that seem to highlight that they were copies of Celtiberian models. The weapon developed in Iberia after La Tène I models, which were adapted to traditional Celtiberian techniques during the late 4th and early 3rd centuries BC. These weapons are quite original in their design, so that they cannot be confused with Gallic types.

Manufacture

By the time of the Roman Republic, which flourished during the Iron Age, the classical world was well-acquainted with steel and the steel-making process. Pure iron is relatively soft, but pure iron is never found in nature. Natural iron ore contains various impurities in solid solution, which harden the reduced metal by producing irregular-shaped metallic crystals. The Gladius is generally made out of steel.

In Roman times, workers reduced ore in a bloomery furnace. The resulting pieces were called blooms, which they further worked to remove slag inclusions from the porous surface.

A recent metallurgical study of two Etrurian swords, one in the form of a Greek kopis from 7th century BC Vetulonia, the other in the form of a gladius Hispaniensis from 4th century BC Chiusa, gives insight concerning the manufacture of Roman swords. The Chiusa sword comes from Romanized Etruria; thus, regardless of the names of the forms (which the authors do not identify), the authors believe the process was continuous from the Etruscans to the Romans.

The Vetulonian sword was crafted by the pattern welding process from five blooms reduced at a temperature of 1163 °C. Five strips of varying carbon content were created. A central core of the sword contained the highest: 0.15–0.25% carbon. On its edges were placed four strips of low-carbon steel, 0.05–0.07%, and the whole thing was welded together by forging on the pattern of hammer blows. A blow increased the temperature sufficiently to produce a friction weld at that spot. Forging continued until the steel was cold, producing some central annealing. The sword was 58 cm (23 in) long.

The Chiusian sword was created from a single bloom by forging from a temperature of 1237 °C. The carbon content increased from 0.05–0.08% at the back side of the sword to 0.35–0.4% on the blade, from which the authors deduce that some form of carburization may have been used. The sword was 40 cm (16 in) long and was characterized by a wasp-waist close to the hilt.

Romans continued to forge swords, both as composites and from single pieces. Inclusions of sand and rust weakened the two swords in the study, and no doubt limited the strength of swords during the Roman period.

Description

The word gladius acquired a general meaning as any type of sword. This use appears as early as the 1st century AD in the Biography of Alexander the Great by Quintus Curtius Rufus. The republican authors, however, appear to mean a specific type of sword, which is now known from archaeology to have had variants.

Gladii were two-edged for cutting and had a tapered point for stabbing during thrusting. A solid grip was provided by a knobbed hilt added on, possibly with ridges for the fingers. Blade strength was achieved by welding together strips, in which case the sword had a channel down the center, or by fashioning a single piece of high-carbon steel, rhomboidal in cross-section. The owner's name was often engraved or punched on the blade.

The hilt of a Roman sword was the capulus. It was often ornate, especially the sword-hilts of officers and dignitaries.

Stabbing was a very efficient technique, as stabbing wounds, especially in the abdominal area, were almost always deadly. However, the gladius in some circumstances was used for cutting or slashing, as is indicated by Livy's account of the Macedonian Wars, wherein the Macedonian soldiers were horrified to see dismembered bodies.

Though the primary infantry attack was thrusting at stomach height, they were trained to take any advantage, such as slashing at kneecaps beneath the shield wall.

The gladius was sheathed in a scabbard mounted on a belt or shoulder strap, some say on the right, some say on the left (refer to the articles cited in the notes). Some say the soldier reached across his body to draw it, and others claim that the position of the shield made this method of drawing impossible. A centurion wore it on the opposite side as a mark of distinction.

Towards the end of the 2nd century AD and during the 3rd century the spatha gradually took the place of the gladius in the Roman legions.

Types

Several different designs were used; among collectors and historical reenactors, the three primary kinds are known as the Mainz gladius, the Fulham gladius, and the Pompeii gladius (these names refer to where or how the canonical example was found). More recent archaeological finds have uncovered an earlier version, the Gladius Hispaniensis (Hispanic sword).

The differences between these varieties are subtle. The original Hispanic sword, which was used during the republic, had a slight "wasp-waist" or "leaf-blade" curvature. The Mainz variety came into use on the frontier in the early empire. It kept the curvature, but shortened and widened the blade and made the point triangular. At home, the less battle-effective Pompeii version came into use. It eliminated the curvature, lengthened the blade, and diminished the point. The Fulham was a compromise, with straight edges and a long point.

Descriptions of the main types follow:

The Mainz and the Pompeii are the two main classification types and served side by side for many years and it was not uncommon to find 4th century legionaries carrying the earlier model.
