Claw Of Archimedes
The Claw of Archimedes ( grc, Ἁρπάγη, translit=harpágē, lit=snatcher; 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 drop an attacking ship partly down in to the water, then either cause the ship to capsize or suddenly drop it. It was dropped onto enemy ships, which would then swing on to defensive forces and destroy them. 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 Ro ...

Quinquereme
From the 4th century BC on, new types of oared warships appeared in the Mediterranean Sea, superseding the trireme and transforming naval warfare. Ships became increasingly large and heavy, including some of the largest wooden ships hitherto constructed. These developments were spearheaded in the Hellenistic Near East, but also to a large extent shared by the naval powers of the Western Mediterranean, specifically Carthage and the Roman Republic. While the wealthy successor kingdoms in the East built huge warships ("polyremes"), Carthage and Rome, in the intense naval antagonism during the Punic Wars, relied mostly on medium-sized vessels. At the same time, smaller naval powers employed an array of small and fast craft, which were also used by the ubiquitous pirates. Following the establishment of complete Roman hegemony in the Mediterranean after the Battle of Actium, the nascent Roman Empire faced no major naval threats. In the 1st century AD, the larger warships were retained ...

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 idiosyncra ...

Catapult
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 un ...

Livy
Titus Livius (; 59 BC – AD 17), known in English as Livy ( ), was a Ancient Rome, 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 familiar terms with members of the Julio-Claudian dynasty and a friend of Augustus, whose young grandnephew, the future emperor Claudius, he exhorted to take up the writing of history. Life Livy was born in Patavium in northern Italy (Roman Empire), 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 in Roman Italy, Italy proper during his lifetime and its inhabitants were given Roman citizenship by Julius Caesar. In his works, Livy often expressed his deep affection an ...

Marcus Claudius Marcellus
Marcus Claudius Marcellus (; 270 – 208 BC), five times elected as consul of the Roman Republic, was an important Roman military leader during the Gallic War of 225 BC and the Second Punic War. Marcellus gained the most prestigious award a Roman general could earn, the ''spolia opima'', for killing the Gallic military leader and king Viridomarus in hand-to-hand combat in 222 BC at the Battle of Clastidium. Furthermore, he is noted for having conquered the fortified city of Syracuse in a protracted siege during which Archimedes, the famous mathematician, scientist, and inventor, was killed, despite Marcellus ordering the soldiers 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 biographers were more concerned with the mi ...

Archimedes
Archimedes of Syracuse (;; ) was a Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Considered the greatest mathematician of ancient history, and one of the greatest of all time,* * * * * * * * * * Archimedes anticipated modern calculus and analysis by applying the concept of the infinitely small and the method of exhaustion to derive and rigorously prove a range of geometrical theorems. These include the area of a circle, the surface area and volume of a sphere, the area of an ellipse, the area under a parabola, the volume of a segment of a paraboloid of revolution, the volume of a segment of a hyperboloid of revolution, and the area of a spiral.

Roman Republic
The Roman Republic ( la, Res publica Romana ) was a form of government of Rome and the era of the classical Roman civilization when it was run through public representation of the Roman people. Beginning with the overthrow of the Roman Kingdom (traditionally dated to 509 BC) and ending in 27 BC with the establishment of the Roman Empire, Rome's control rapidly expanded during this period—from the city's immediate surroundings to hegemony over the entire Mediterranean world. Roman society under the Republic was primarily a cultural mix of Latin and Etruscan societies, as well as of Sabine, Oscan, and Greek cultural elements, which is especially visible in the Roman Pantheon. Its political organization developed, at around the same time as direct democracy in Ancient Greece, with collective and annual magistracies, overseen by a senate. The top magistrates were the two consuls, who had an extensive range of executive, legislative, judicial, military, and religious powers ...
