Gladius (English pronunciation://; Latin: glădĭus, pronounced [ˈɡladiʊs]) was one Latin word for sword and is used to represent the primary sword of Ancient Roman foot soldiers. Early ancient Roman swords were similar to those used by the Greeks. From the third century BC, the Romans adopted swords similar to those used by the Celtiberians and others throughout the early part of the conquest of Hispania. This sword was known as the gladius hispaniensis, or "Hispanic Sword".
A fully equipped Roman legionary after the reforms of Gaius Marius was armed with a shield (scutum), one or two javelins (pila), a sword (gladius), often a dagger (pugio), and perhaps, in the later Empire period, darts (plumbatae). Conventionally, the javelins would be thrown to disable the shields and disrupt the formation of the enemy before engaging in close combat, for which the gladius would be drawn. The soldier generally led with his shield and thrust with his sword. All types of gladius appear to have additionally been suitable for cutting and chopping motions as well as for thrusting.
The name is a Latin masculine second declension noun, its plural being gladiī. Notwithstanding the word gladius in Latin refers to any sword, not specifically the modern definition of a gladius. Gladius is used in literature as early as the plays of Plautus (Casina, Rudens).
Predecessors and origins
Livy relates the storey 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 happened in the consulships of C. Sulpicius and C. Licinius in about 361 BC, much before the Punic Wars, but throughout the frontier wars with the Gauls (366-341 BC). One theory therefore proposes the borrowing of the word gladius from *kladi- throughout this period, relying on the principle that k becomes g in Latin. Ennius attests the word. Gladius might have replaced ensis, which in the literary periods was used mainly by the poets.
The exact origin of the gladius Hispanus is an argued topic, while it is likely that it descended ultimately from Celtic swords of the La Tene and Hallstat periods; it is unknown if it descended directly from Celtiberian troops of the Punic Wars, or through Gallic troops of the Gallic Wars.
The Celtiberian source of the weapon has been reinforced throughout the later decades. Recent findings of quite early Roman gladii highlights that they were copies of Celtiberian models. The weapon was developed in Iberia after La Téne I models, which were adapted to traditional Celtiberian techniques throughout the late fourth and early third centuries BC. These weapons are quite original in their design, so that they can't be confused with Gallic types.
By the time of the Roman Republic, which flourished throughout 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, ore was reduced in a bloomery furnace. The resulting pieces were called blooms, which were further worked to remove slag inclusions from its porous surface.
A recent metallurgical study of two Etrurian swords, one in the form of a Greek kopis from seventh century BC Vetulonia, the additional in the form of a gladius Hispaniensis from fourth century BC Chiusa, gives a few 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 don't 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 a few 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 a few form of carburization might have been used. The sword was 40 cm (16 in) long and was characterised by a wasp-waist close to the hilt.
Roman swords continued to be forged 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 throughout the Roman period.
The word gladius acquired a general meaning as any type of sword. This use appears as early as the first 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 throughout 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 quite efficient technique, as stabbing wounds, especially in the abdominal area, were almost always deadly. Notwithstanding the gladius in a few 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, a few say on the right, a few 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 second century AD and throughout the third century the spatha gradually took the place of the gladius in the Roman legions.
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 throughout 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:
- Gladius Hispaniensis: Used from around 216 BC until 20 BC. Blade length ~60–68 cm (24–27 in). Sword length ~75–85 cm (30–33 in). Sword width ~5 cm (2.0 in). This was the largest and heaviest of the gladii. Earliest and longest blade of the gladii, pronounced leaf-shape compared to the additional forms. Max weight ~1 kg (2.2 lb) for the largest versions, most likely a standard example would weigh ~900 g (2.0 lb) (wooden hilt).
- Mainz Gladius: Mainz was founded as the Roman permanent camp of Moguntiacum probably in 13 BC. This large camp provided a population base for the growing city around it. Sword manufacture probably began in the camp and was continued in the city; for example, Gaius Gentilius Victor, a veteran of Legio XXII, used his discharge bonus on retirement to set up a business as a negotiator gladiarius, a manufacturer and dealer of arms. Swords made at Mainz were sold extensively to the north. The Mainz variety is characterised by a slight waist running the length of the blade and a long point. Blade length ~50–55 cm (20–22 in). Sword length ~65–70 cm (26–28 in). Blade width ~7 cm (2.8 in). Sword weight ~800 g (1.8 lb) (wooden hilt).
- Fulham Gladius or Mainz-Fulham Gladius: The sword that gave the name to the type was dredged from the Thames near Fulham and must therefore date to a time after the Roman occupation of Britain began. That would have been after the invasion of Aulus Plautius in 43 AD. It was used until the end of the same century. It is considered the conjunction point between Mainz and Pompei. Some consider it an evolution or the same as the Mainz type. The blade is slightly narrower than the Mainz variety. The main difference is the triangular tip. Blade length ~50–55 cm (20–22 in). Sword length ~65–70 cm (26–28 in). Blade width ~6 cm (2.4 in). Sword weight ~700 g (1.5 lb) (wooden hilt).
- Pompeii Gladius (or Pompeianus or Pompei): Named by modern historians after the Roman town of Pompeii, this Gladius was by far the most popular one. Four instances of the sword type were found in Pompeii, with others turning up elsewhere. The sword has parallel cutting edges and a triangular tip. This is the shortest of the gladii. Observe that it is often confused with the spatha which was a longer, slashing weapon used initially by mounted auxilia. Over the years the Pompeii got longer, these later versions are referred to as semi-spathas. Blade length ~45–50 cm (18–20 in). Sword length ~60–65 cm (24–26 in). Blade width ~5 cm (2.0 in). Sword weight ~700 g (1.5 lb) (wooden hilt).
The Mainz and the Pompeii are the two main classification types and served side by side for a large number of years and it wasn't uncommon to find fourth century legionaries carrying the earlier model.
