Pilum
The pilum (Latin: [ˈpiːɫʊ̃]; pl.: pila) was a javelin commonly used by the Roman army in ancient times. It was generally about 2 m (6 ft 7 in) long overall, consisting of an iron shank about 7 mm (0.28 in) in diameter and 600 mm (24 in) long with a pyramidal head, attached to a wooden shaft by either a socket or a flat tang.
The pilum may have originated from an Italic tribe known as the Samnites. It also may have been influenced by Celtiberian and Etruscan weapons. The pilum may have derived from a Celtiberian weapon known as the falarica. Archaeological excavations have disclosed pila in tombs at the Etruscan city of Tarquinia.[page needed] The oldest finds of pila are from the Etruscan settlements of Vulci and Talamone. The first identified written reference to the pilum comes from The Histories of Polybius. According to Polybius, more heavily armed Roman military soldiers used a spear called the hyssoí. This may have been the pilum. The precursor to the pilum was the hasta. It is unclear how soon it was replaced by the pilum. Polybius mentioned that it was an important contributor to the Roman victory at the Battle of Telamon in 225 BCE.
A socketed pilum head measuring 295 mm (11.6 in) in length was discovered in the Cave of the Swords, a refuge cave in the Judaean Desert near Ein Gedi. Its deliberate concealment in a remote crevice suggests it may have been removed from a battlefield or taken as booty by a Jewish rebel—possibly for reuse—most likely during the Bar Kokhba revolt (132–136 CE).
Use of the pilum was discontinued by Roman military in the second century.
A pilum had a total weight between 1 and 2.5 kg (2 and 5 lb),[citation needed] with the versions produced during the earlier Republic being slightly heavier than those produced in the later Empire.
The weapon had a hard pyramidal tip, but the shank was sometimes made of softer iron. The softness could cause the shank to bend after impact, thus rendering the weapon useless to the enemy. According to Davide Antonio Secci, the pilum was not meant to bend on impact, but instead was meant to break. If a pilum struck a shield, it might embed itself, and the bending of the shank would force the enemy to discard his shield as unusable without removing the pilum, or carry around the shield burdened by the weight of the pilum. Even if the shank did not bend, the pyramidal tip still made it difficult to pull out. Many cases occurred, though, in which the whole shank was hardened, making the pilum more suitable as a close-quarters melee weapon and also making it usable by enemy soldiers.
Although the bending of its shank is commonly seen as an integral part of the weapon's design and as an intentional feature, little evidence suggests that. The most commonly found artifacts suggest that the pilum was constructed to use the weight of the weapon to cause damage, most likely to be able to impale through armour and reach the enemy soldier's body. The combination of the weapon's weight and the aforementioned pyramidal tip (the design of which was seen in the Middle Ages in the form of bodkin arrow tips), made the pilum a formidable armour-piercing weapon. If the weapon was meant to be used against armour and to use its mass (as opposed to its speed) to cause damage, the bending of the shank seems to be a beneficial result of its intended use, which is to pierce through layers of armour. That the pilum needed to pierce layers of armour (through the shield, into body armour and past clothing) necessitated a lengthy shank, which was prone to bending. M.C. Bishop wrote that the momentum of the pilum caused the shank to bend upon impact, and although unintended, that proved a useful characteristic of the weapon. However, a newer work by M. C. Bishop states that pila are "unlikely to bend under their own weight when thrown and striking a target or ground"; rather, human intervention such as improper removal of a pilum stuck in a target is responsible in some way, and Caesar's writings should be interpreted as the pilum bending when soldiers tried to remove them.
Since the pyramidal tip of a pilum was wider than the rest of the shank, once it had penetrated a shield, it left behind a hole larger than the rest of the shank, and it could move through the shield with little resistance, stabbing the soldier behind. The length of the shank and its depth of penetration also made pulling it out of a shield more difficult, even if it failed to bend. If the bearer of the shield was charging and a pilum penetrated the shield, the end of the heavy shaft of the pilum would hit the ground, holding the shield in place. Some pila had a spike on the end of the shaft, which made it easier to dig into the ground.[citation needed]
