Claw Of Archimedes
The Claw of Archimedes (; also known as the iron hand) was an ancient weapon devised by Archimedes to defend the seaward portion of Syracuse's city wall against amphibious assault. Although its exact nature is unclear, the accounts of ancient historians seem to describe it as a sort of crane equipped with a grappling hook that was able to lift an attacking quinquereme by the bow. By then releasing the claw the ship would fall onto the rocks or water below, inevitably capsizing. The claw could allegedly shake boats with such force that the crew would be thrown into the sea. These machines featured prominently during the Second Punic War in 214 BC, when the Roman Republic attacked Syracuse with a fleet of 60 quinqueremes under Marcus Claudius Marcellus. When the Roman fleet approached the city walls under cover of darkness, the machines were deployed, sinking many ships and throwing the attack into confusion. Historians such as Livy attributed heavy Roman losses to these m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marcus Claudius Marcellus
Marcus Claudius Marcellus (; 270 – 208 BC) was a Roman general and politician during the 3rd century BC. Five times elected as Roman consul, consul of the Roman Republic (222, 215, 214, 210, and 208 BC). Marcellus gained the most prestigious award a Roman general could earn, the ''spolia opima'', for killing the Gallic king Viridomarus in single combat in 222 BC at the Battle of Clastidium. Furthermore, he is noted for having conquered the fortified city of Siege of Syracuse (214–212 BC), Syracuse in a protracted siege during which Archimedes, the famous mathematician, scientist, and inventor, was killed, despite Marcellus ordering the soldiers under his command not to harm him. Marcus Claudius Marcellus died in battle in 208 BC, leaving behind a legacy of military conquests and a reinvigorated Roman legend of the ''spolia opima''. Early life: distinguished soldier and politician Little is known of Marcus Claudius Marcellus' early years, since ancient historians and biograp ...

Greek Fire
Greek fire was an incendiary weapon system used by the Byzantine Empire from the seventh to the fourteenth centuries. The recipe for Greek fire was a closely-guarded state secret; historians have variously speculated that it was based on saltpeter, sulfur, or quicklime, but most modern scholars agree that it was based on petroleum mixed with resins, comparable in composition to modern napalm. Byzantine sailors would toss grenades loaded with Greek fire onto enemy ships or spray it from tubes. Its ability to burn on water made it an effective and destructive naval incendiary weapon, and rival powers tried unsuccessfully to copy the material. Name Usage of the term "Greek fire" has been general in English and most other languages since the Crusades. Original Byzantine sources called the substance a variety of names, such as "sea fire" (Medieval Greek: ), "Roman fire" ( ), "war fire" ( ), "liquid fire" ( ), "sticky fire" ( ), or "manufactured fire" ( ).

Secrets Of The Ancients
Secrecy is the practice of hiding information from certain individuals or groups who do not have the "need to know", perhaps while sharing it with other individuals. That which is kept hidden is known as the secret. Secrecy is often controversial, depending on the content or nature of the secret, the group or people keeping the secret, and the motivation for secrecy. Secrecy by government entities is often decried as excessive or in promotion of poor operation; excessive revelation of information on individuals can conflict with virtues of privacy and confidentiality. It is often contrasted with social transparency. Secrecy can exist in a number of different ways: encoding or encryption (where mathematical and technical strategies are used to hide messages), true secrecy (where restrictions are put upon those who take part of the message, such as through government security classification) and obfuscation, where secrets are hidden in plain sight behind complex idiosyncrat ...

Catapult
A catapult is a ballistics, ballistic device used to launch a projectile at 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 (mechanics), tension or Torsion (mechanics), 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 which allow the catapult to launch a projectile such as rocks, cannon balls, or debris. During wars in the ancient times, the catapult was usually known to be the strongest heavy weaponry. In modern times the term can apply to devices ranging from a simple hand-held implement (also called a "slingshot") to a mechanism for Aircraft catapult, launching aircraft from a ship. The earliest catapults date to at least the 7th century BC, with Kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livy
Titus Livius (; 59 BC – AD 17), known in English as Livy ( ), was a Roman historian. He wrote a monumental history of Rome and the Roman people, titled , covering the period from the earliest legends of Rome before the traditional founding in 753 BC through the reign of Augustus in Livy's own lifetime. He was on good terms with members of the Julio-Claudian dynasty and was a friend of Augustus. Livy encouraged Augustus’s young grandnephew, the future emperor Claudius, to take up the writing of history. Life Livy was born in Patavium in northern Italy, now modern Padua, probably in 59 BC. At the time of his birth, his home city of Patavium was the second wealthiest on the Italian peninsula, and the largest in the province of Cisalpine Gaul (northern Italy). Cisalpine Gaul was merged into Italy proper during his lifetime and its inhabitants were given Roman citizenship by Julius Caesar. In his works, Livy often expressed his deep affection and pride for Patavium, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siege Of Syracuse (214–212 BC)
A siege () . is a military blockade of a city, or fortress, with the intent of conquering by attrition, or by well-prepared assault. Siege warfare (also called siegecrafts or poliorcetics) is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy. A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a quick assault, and which refuses to surrender. Sieges involve surrounding the target to block provision of supplies and reinforcement or escape of troops (a tactic known as "investment"). This is typically coupled with attempts to reduce the fortifications by means of siege engines, artillery bombardment, mining (also known as sapping), or the use of deception or treachery to bypass defenses. Failing a military outcome, sieges can often be deci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roman Republic
The Roman Republic ( ) was the era of Ancient Rome, classical Roman civilisation beginning with Overthrow of the Roman monarchy, the overthrow of the Roman Kingdom (traditionally dated to 509 BC) and ending in 27 BC with the establishment of the Roman Empire following the War of Actium. During this period, Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean Sea, Mediterranean world.

Its political organisation developed at around the same time as direct democracy in Ancient Greece, with collective and annual magistracies, overseen by Roman Senate, a senate.
