Catapults
A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. A catapult uses the sudden release of stored potential energy to propel its payload. Most convert tension or torsion energy that was more slowly and manually built up within the device before release, via springs, bows, twisted rope, elastic, or any of numerous other materials and mechanisms. In use since ancient times, the catapult has proven to be one of the most persistently effective mechanisms in warfare. In modern times the term can apply to devices ranging from a simple hand-held implement (also called a "slingshot") to a mechanism for launching aircraft from a ship. The earliest catapults date to at least the 7th century BC, with King Uzziah, of Judah, recorded as equipping the walls of Jerusalem with machines that shot "great stones". Catapults are mentioned in Yajurveda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Catapult
An aircraft catapult is a device used to allow aircraft to take off from a very limited amount of space, such as the deck of a vessel, but can also be installed on land-based runways in rare cases. It is now most commonly used on aircraft carriers, as a form of assisted take off. In the form used on aircraft carriers the catapult consists of a track, or slot, built into the flight deck, below which is a large piston or ''shuttle'' that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle. Other forms have been used historically, such as mounting a launching cart holding a seaplane on a long girder-built structure mounted on the deck of a warship or merchant vessel, but most catapults share a similar sliding track concept. Different means have been used to propel the catapult, such as weight and derrick, gunpowder, flywheel, air pressure, hydraulic, and steam ...

Siege Of Motya
The siege of Motya took place either in 398 or 397 BC in western Sicily. Dionysius, after securing peace with Carthage in 405 BC, had steadily increased his military power and had tightened his grip on Syracuse. He had fortified Syracuse against sieges and had created a large army of mercenaries and a large fleet, in addition to employing the catapult and quinqueremes for the first time in history. In 398 BC, he attacked and sacked the Phoenician city of Motya despite the Carthaginian relief effort led by Himilco. Carthage also lost most of her territorial gains secured in 405 BC after Dionysius declared war on Carthage in 398 BC. Background Carthage had stayed away from Sicilian affairs for 70 years after the defeat at Himera in 480 BC. However, Carthage, responding to the appeal for aid of Segesta against Selinus, had sent an expedition to Sicily, resulting in the sacking of Selinus and Himera in 409 BC under the leadership of Hannibal Mago. Responding to Greek raids on her ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trebuchet
A trebuchet (french: trébuchet) is a type of catapult that uses a long arm to throw a projectile. It was a common powerful siege engine until the advent of gunpowder. The design of a trebuchet allows it to launch projectiles of greater weights and further distances than that of a traditional catapult. There are two main types of trebuchet. The first is the traction trebuchet, or mangonel, which uses manpower to swing the arm. It first appeared in China in the 4th century BC. Carried westward by the Avars, the technology was adopted by the Byzantines in the late 6th century AD and by their neighbors in the following centuries. The later, and often larger and more powerful, counterweight trebuchet, also known as the counterpoise trebuchet, uses a counterweight to swing the arm. It appeared in both Christian and Muslim lands around the Mediterranean in the 12th century, and was carried back to China by the Mongols in the 13th century. Etymology and terminology It is uncer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
Mangonel
The mangonel, also called the traction trebuchet, was a type of trebuchet used in Ancient China starting from the Warring States period, and later across Eurasia by the 6th century AD. Unlike the later counterweight trebuchet, the mangonel operated on manpower pulling cords attached to a lever and sling to launch projectiles. Although the mangonel required more men to function, it was also less complex and faster to reload than the torsion-powered onager which it replaced in early Medieval Europe. It was replaced as the primary siege weapon in the 12th and 13th centuries by the counterweight trebuchet. A common misconception about the mangonel is that it was a torsion siege engine. Etymology ''Mangonel'' is probably derived from the Greek ''mangana'', "a generic term for construction machinery." It could also be derived from ''mangon'', a French hard stone found in the south of France. In Latin it is called a ''manganum'', in French a ''manganeau'', and in English a ''mangonel ...

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 ...

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...

Ancient Greeks
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient India
According to consensus in modern genetics, anatomically modern humans first arrived on the Indian subcontinent from Africa between 73,000 and 55,000 years ago. Quote: "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka." However, the earliest known human remains in South Asia date to 30,000 years ago. Settled life, which involves the transition from foraging to farming and pastoralism, began in South Asia around 7000 BCE. At the site of Mehrgarh presence can be documented of the domestication of wheat and barley, rapidly followed by that of goats, sheep, and cattle. By 4500 BCE, settled life had spread more widely, and began to gradually evolve into the Indus Valley civilisation, an early civilisation of the Old World, which was contemporaneous with Ancient Egypt and Mesopotamia. This civilisation flourished between 2500 BCE and 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diodorus Siculus
Diodorus Siculus, or Diodorus of Sicily ( grc-gre, Διόδωρος ; 1st century BC), was an ancient Greek historian. He is known for writing the monumental universal history ''Bibliotheca historica'', in forty books, fifteen of which survive intact, between 60 and 30 BC. The history is arranged in three parts. The first covers mythic history up to the destruction of Troy, arranged geographically, describing regions around the world from Egypt, India and Arabia to Europe. The second covers the time from the Trojan War to the death of Alexander the Great. The third covers the period to about 60 BC. ''Bibliotheca'', meaning 'library', acknowledges that he was drawing on the work of many other authors. Life According to his own work, he was born in Agyrium in Sicily (now called Agira). With one exception, antiquity affords no further information about his life and doings beyond his written works. Only Jerome, in his ''Chronicon'' under the "year of Abraham 1968" (49 BC), w ...
