Manuballista
The ''cheiroballistra'' ( el, χειροβαλλίστρα) or ''manuballista'' (Latin), which translates in all its forms to "hand ballista", was an imperial-era Roman siege engine. Designed by Hero of Alexandria and mostly composed of metal (the spring mechanism and the skeins), it shot bolts that were smaller than those in other forms of ballistae and generally made of metal. It was the next major improvement after the '' scorpio''.Warry, J. (1995). ''Warfare in the Classical World''. ''P. 178'' Salamander Books Ltd., London: United Kingdom. .

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

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 ...

Roman Siege Engines
Roman siege engines were, for the most part, adapted from Hellenistic siege technology. Relatively small efforts were made to develop the technology; however, the Romans brought an unrelentingly aggressive style to siege warfareGoldsworthy 2000: 144 that brought them repeated success. Up to the first century BC, the Romans utilized siege weapons only as required and relied for the most part on ladders, towers and rams to assault a fortified town. ''Ballistae'' were also employed, but held no permanent place within a legion's roster, until later in the republic, and were used sparingly. Julius Caesar took great interest in the integration of advanced siege engines, organizing their use for optimal battlefield efficiency.Keppie 1984: 99 Army engineering corps To facilitate this organization and the army's self-sufficiency, an engineering corps was developed. An officer of engineers, or ''praefectus fabrum'', is referenced in armies of the late republic, but this post is not v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hero Of Alexandria
Hero of Alexandria (; grc-gre, Ἥρων ὁ Ἀλεξανδρεύς, ''Heron ho Alexandreus'', also known as Heron of Alexandria ; 60 AD) was a Greece, Greek mathematician and engineer who was active in his native city of Alexandria, Roman Egypt. He is often considered the greatest experimenter of antiquity and his work is representative of the Hellenistic civilization, Hellenistic scientific tradition. Hero published a well-recognized description of a Steam engine, steam-powered device called an ''aeolipile'' (sometimes called a "Hero engine"). Among his most famous inventions was a windmill, windwheel, constituting the earliest instance of Wind power, wind harnessing on land. He is said to have been a follower of the atomism, atomists. In his work ''Mechanics'', he described pantographs. Some of his ideas were derived from the works of Ctesibius. In mathematics he is mostly remembered for Heron's formula, a way to calculate the area of a triangle using only the lengths of it ...

Scorpio (weapon)
The ''scorpio'' or scorpion was a type of Roman torsion siege engine and field artillery piece. It was described in detail by the early-imperial Roman architect and engineer Vitruvius in the 1st century BC and by the 4th century AD officer and historian Ammianus Marcellinus.Ammianus Marcellinus, ''Roman History'', XXIII:4. Design Two versions are known: a horizontal two-armed variety like a ballista and a one-armed, vertical version otherwise referred to as an ''onager''. The fourth century army officer and historian Ammianus Marcellinus witnessed the use of ''scorpiones'' during several engagements in the Persian wars of Constantius II, and described the one-armed version as synonymous with the ''onager'', with the vertical upraised arm as the 'scorpion's sting'. The complexity of construction and in particular the torsion springs (which the Romans referred to as ''tormenta'') led to great sensitivity to any variation in temperature or moisture, which limited their use.

Crossbow
A crossbow is a ranged weapon using an elastic launching device consisting of a 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 of a long firearm. Crossbows shoot arrow-like projectiles called '' bolts'' or ''quarrels''. A person who shoots crossbow is called a ''crossbowman'' or an '' 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 draw manually by pitching the bowstring with fingers, pulling it back with arm and back muscles and then holding that same form in order to aim (which distresses the body and demands significant physical strength and stamina); while a crossbow utilizes a locking mechanism to maintain the draw, limiting the shooter's exertion to only pulling the string into lock and then releasing the shot ...
