A javelin is a light spear designed primarily to be thrown, historically as a ranged weapon, but today predominantly for sport. The javelin is almost always thrown by hand, unlike the sling, bow, and crossbow, which launch projectiles with the aid of a hand-held mechanism. However, devices do exist to assist the javelin thrower in achieving greater distance, such as spear-throwers or the amentum. A warrior or soldier armed primarily with one or more javelins is a javelineer. The word javelin comes from Middle English and it derives from Old French javelin, a diminutive of javelot, which meant spear. The word javelot probably originated from one of the Celtic languages. Prehistory There is archaeological evidence that javelins and throwing sticks were already in use by the last phase of the Lower Paleolithic. Seven spear-like objects were found in a coal mine in the city of Schöningen, Germany. Stratigraphic dating indicates that the weapons are about 400,000 years old. The excavated items were made of spruce (Picea) trunk and were between 1.83 and 2.25 metres long. They were manufactured with the maximum thickness and weight situated at the front end of the wooden shaft. The frontal centre of gravity suggests that these weapons were used as javelins. A fossilized horse shoulder blade with a projectile wound, dated to 500,000 years ago, was revealed in a gravel quarry in the village of Boxgrove, England. Studies suggested that the wound was probably caused by a javelin. Classical age Ancient Egypt In History of Ancient Egypt: Volume 1 (1882), George Rawlinson depicts the javelin as an offensive weapon used by the Ancient Egyptian military. It was lighter in weight than that used by other nations. He describes the Ancient Egyptian javelin's features: It consisted of a long thin shaft, sometimes merely pointed, but generally armed with a head, which was either leaf-shaped, or like the head of a spear, or else four-sided, and attached to the shaft by projections at the angles. A strap or tasseled head was situated at the lower end of the javelin: it allowed the javelin thrower to recover his javelin after throwing it. Egyptian military trained from a young age in special military schools. Focusing on gymnastics to gain strength, hardiness and endurance in childhood, they learned to throw the javelin – along with practicing archery and the battle-axe – when they grew older, before entering a specific regiment.
