Crossbow TenPoint Stealth SS
A crossbow is a ranged weapon using an Elasticity (physics), elastic launching device consisting of a Bow and arrow, bow-like assembly called a ''prod'', mounted horizontally on a main frame called a ''tiller'', which is hand-held in a similar fashion to the stock (firearms), stock of a long gun, long firearm. Crossbows shoot arrow-like projectiles called ''crossbow bolt, bolts'' or ''quarrels''. A person who shoots crossbow is called a ''crossbowman'' or an ''arbalist (crossbowman), arbalist'' (after the arbalest, a European crossbow variant used during the 12th century). Although crossbows and bows use the same launch principle, the difference is that an archer must maintain a bow's bow draw, draw manually by pitching the bowstring with fingers, pulling it back with arm and back muscles and then holding that same form (exercise), form in order to aim (which distresses the body and demands significant physical strength and endurance, stamina); while a crossbow utilizes a lock ...

Endurance
Endurance (also related to sufferance, resilience, constitution, fortitude, and hardiness) is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from and have immunity to trauma, wounds or fatigue. It is usually used in aerobic or anaerobic exercise. The definition of 'long' varies according to the type of exertion – minutes for high intensity anaerobic exercise, hours or days for low intensity aerobic exercise. Training for endurance can reduce the ability to exert endurance strength unless an individual also undertakes resistance training to counteract this effect. When a person is able to accomplish or withstand a higher amount of effort than their original capabilities their endurance is increasing which to many personnel indicates progress. In looking to improve one's endurance they may slowly increase the amount of repetitions or time spent, if higher repetitions are taken rap ...

Bow And Arrow
The bow and arrow is a ranged weapon system consisting of an elastic launching device (bow) and long-shafted projectiles ( arrows). Humans used bows and arrows for hunting and aggression long before recorded history, and the practice was common to many prehistoric cultures. They were important weapons of war from ancient history until the early modern period, where they were rendered increasingly obsolete by the development of the more powerful and accurate firearms. Today, bows and arrows are mostly used for hunting and sports. Archery is the art, practice, or skill of using bows to shoot arrows.Paterson ''Encyclopaedia of Archery'' p. 17 A person who shoots arrows with a bow is called a bowman or an archer. Someone who makes bows is known as a bowyer,Paterson ''Encyclopaedia of Archery'' p. 31 someone who makes arrows is a fletcher,Paterson ''Encyclopaedia of Archery'' p. 56 and someone who manufactures metal arrowheads is an arrowsmith.Paterson ''Encyclopaedia of Arche ...

Siege Engine
A siege engine is a device that is designed to break or circumvent heavy castle doors, thick city walls and other fortifications in siege warfare. Some are immobile, constructed in place to attack enemy fortifications from a distance, while others have wheels to enable advancing up to the enemy fortification. There are many distinct types, such as siege towers that allow foot soldiers to scale walls and attack the defenders, battering rams that damage walls or gates, and large ranged weapons (such as ballistae, catapults/trebuchets and other similar constructions) that attack from a distance by launching projectiles. Some complex siege engines were combinations of these types. Siege engines are fairly large constructions – from the size of a small house to a large building. From antiquity up to the development of gunpowder, they were made largely of wood, using rope or leather to help bind them, possibly with a few pieces of metal at key stress points. They could launch simple ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ...

Ballista
The ballista (Latin, from Greek βαλλίστρα ''ballistra'' and that from βάλλω ''ballō'', "throw"), plural ballistae, sometimes called bolt thrower, was an ancient missile weapon that launched either bolts or stones at a distant target. Developed from earlier Greek weapons, it relied upon different mechanics, using two levers with torsion springs instead of a tension prod (the bow part of a modern crossbow). The springs consisted of several loops of twisted skeins. Early versions projected heavy darts or spherical stone projectiles of various sizes for siege warfare. It developed into a smaller precision weapon, the '' scorpio'', and possibly the ''polybolos''. Greek weapon The early ballistae in Ancient Greece were developed from two weapons called oxybeles and gastraphetes. The gastraphetes ('belly-bow') was a handheld crossbow. It had a composite prod and was spanned by bracing the front end of the weapon against the ground while placing the end of a slider ...

War Of The Heavenly Horses
The War of the Heavenly Horses () or the Han–Dayuan War () was a military conflict fought in 104 BC and 102 BC between the Chinese Han dynasty and the Saka-ruled (Scythian) Greco-Bactrian kingdom known to the Chinese as Dayuan, in the Ferghana Valley at the easternmost end of the former Persian Empire (between modern-day Uzbekistan, Kyrgyzstan and Tajikistan). The war was allegedly instigated by trade disputes compounded by the extended geopolitics surrounding the Han-Xiongnu War, resulting in two Han expeditions that eventuated in a decisive Han victory, allowing Han China to expand its hegemony deep into Central Asia (then known to the Chinese as the Western Regions). Reprinted as an advertisement feature: Emperor Wu of Han had received reports from diplomat Zhang Qian that Dayuan owned fast and powerful Ferghana horses known as the "heavenly horses", which would help greatly with improving the quality of their cavalry mounts when fighting the Xiongnu horse nomads, so ...

Qin's Wars Of Unification
Qin's wars of unification were a series of military campaigns launched in the late 3rd century BC by the Qin state against the other six major Chinese states — Han, Zhao, Yan, Wei, Chu and Qi. Between 247 BC and 221 BC, Qin had emerged as one of the most powerful of the Seven Warring States in China. In 230 BC, Ying Zheng, the King of Qin, unleashed the final campaigns of the Warring States period, setting out to conquer the remaining states one by one. Following the fall of Qi in 221 BC, China was unified under Qin control. Ying Zheng declared himself "Qin Shi Huang" (meaning "First Emperor of Qin") and established the Qin dynasty, becoming the first sovereign ruler of a unified China. Background Rise of Qin and early conquests Over the course of the Warring States period, the Qin state had evolved to become the most powerful of the seven major states in China, particularly after Shang Yang's reforms in the mid 4th century BC. The other six states would repeate ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ranged Weaponry
A ranged weapon is any weapon that can engage targets beyond hand-to-hand distance, i.e. at distances greater than the physical reach of the user holding the weapon itself. The act of using such a weapon is also known as shooting. It is sometimes also called projectile weapon or missile weapon because it typically works by launching solid projectiles ("missiles"), though technically a fluid-projector (which throws out pressurized streams of liquid or even gas) and a directed-energy weapon (which does not involve any tangible projectile) are also ranged weapons. In contrast, a weapon intended to be used in hand-to-hand combat is called a melee weapon. Ranged weapons give the attacker an advantage, since the target is often getting hit from beyond immediate visual range, therefore making it more difficult for the defenders to react and hitting back effectively. It also puts distance between the attacker and the opponent, which is a safer combat option since the close physical ...

Gastraphetes
The gastraphetes ( grc, γαστραφέτης, , belly-releaser), also called belly bow or belly shooter, was a hand-held crossbow used by the Ancient Greeks. It was described in the 1st century AD by the Greek author Heron of Alexandria in his work ''Belopoeica'', which draws on an earlier account of the famous Greek engineer Ctesibius ( fl. 285–222 BC). Heron identifies the gastraphetes as the forerunner of the later catapult, which places its invention some unknown time prior to c. 420 BC. Unlike later Roman and medieval crossbows, spanning the weapon was not done by pulling up the string, but by pushing down an elaborate slider mechanism. Description A fairly detailed description and drawing of the gastraphetes appears in Heron's ''Belopoeica'' (Ancient Greek Βελοποιικά, English translation: ''On arrow-making''), drawn from the account by the 3rd-century BC engineer Ctesibius. The weapon was powered by a composite bow. It was cocked by resting the stomach in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
