Gladius

Gladius is a Latin masculine noun. The nominative plural of it is . However, in Latin refers to any sword, not only the sword described here. The word appears in literature as early as the plays of Plautus (Casina, Rudens). Gladius is generally believed to be a Celtic loan in Latin (perhaps via an Etruscan intermediary), derived from ancient Celtic or "sword" (whence modern Welsh "sword", modern Breton , Old Irish /Modern Irish [itself perhaps a loan from Welsh]; the root of the word may survive in the Old Irish verb claidid "digs, excavates" and anciently attested in the Gallo-Brittonic place name element cladia/clado "ditch, trench, valley hollow"). Modern English words derived from include gladiator ("swordsman") and gladiolus ("little sword", from the diminutive form of gladius), a flowering plant with sword-shaped leaves. ==Predecessors and origins==

According to Polybius, the sword used by the Roman army during the Battle of Telamon in 225 BC, though deemed superior to the cumbersome Gallic swords, was mainly useful to thrust. These thrusting swords used before the adoption of the Gladius were possibly based on the Greek xiphos. A text attributed to Polybius describes the adoption of this design by the Romans even before the end of the war, which canonical Polybius reaffirms by calling the later Roman sword gladius hispaniensis in Latin and iberiké machaira in Greek. In 70 BC, both Claudius Quadrigarius and Livy relate the story of Titus Manlius Torquatus using a "Hispanic sword" (gladius Hispanus) in a duel with a Gaul in 361 BC. However, the Gladius was not yet used by the Romans in the 4th century BC, and because of that this has been traditionally considered a terminological anachronism caused by the long established naming convention. These weapons are quite original in their design, so that they cannot be confused with Gallic types. As for the origin of the word gladius, one theory proposes the borrowing of the word from *kladi- during the Gallic wars, relying on the principle that K often became G in Latin. Ennius attests the word gladius may have replaced ensis, which until then was used mainly by poets. ==Manufacturing==

Technique By the time of the Roman Republic, which flourished during the Iron Age, steel and the steel-making process was known to the classical world. 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 was 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 roman kopis from 7th century BC Vetulonia, the other in the form of a gladius Hispaniensis from 4th century BC Clusium (Chiusi), gives insight concerning the manufacture of Roman swords. The Chiusi 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 . 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 long. ==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 centre, 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 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. ==Variations==

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. 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. Gladius Hispaniensis The gladius Hispaniensis was a Roman sword used from around 216 BC until 20 BC. Its blade had a length of , and the sword was long. The width of the sword was . It was the largest and heaviest of the gladii, weighing or . This gladius was also the earliest and longest blade. It had a pronounced leaf-shape. Mainz Gladius The Mainz Gladius is made of heavily corroded iron and a sheath made of tinned and gilded bronze. The blade was long and in width. The sword was long. The sword weighed . The point of the sword was more triangular than the Gladius Hispaniensis. The Mainz Gladius still had wasp-waisted curves. The decoration on the scabbard illustrates the ceding of military victory to Augustus by Tiberius after a successful Alpine campaign. Augustus is semi-nude, and sits in the pose of Jupiter, flanked by the Roman gods of Victory and Mars Ultor, while Tiberius, in military dress, presents Augustus with a statuette of Victory. Fulham gladius The Fulham gladius or Mainz-Fulham gladius was a Roman sword that was used after Aulus Plautius' invasion of Britain in 43 AD. The Romans used it until the end of the 1st century. The Fulham gladius has a triangular tip. The length of the blade is . The length of the sword is . The width of the blade is . The swords weighs (wooden hilt). A full size replica can be seen at Fulham Palace, Fulham. Pompeii gladius The Pompeii gladius was named by modern historians after the Roman town of Pompeii. This type of gladius was by far the most popular one. Four examples 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. It is often confused with the spatha, which was a longer, slashing weapon used initially by mounted auxilians. Over the years, the Pompeii got longer, and these later versions are called semi-spathes. The length of the blade was . The length of the sword is . The width of the blade is . The sword weighs (wooden hilt). ==See also==
