Ases
The ' (: '), occasionally ''assarius'' (: ''assarii''; ), was a bronze, and later copper, coin used during the Roman Republic and Roman Empire. Republican era coinage The Romans replaced the usage of Greek coins, first by bronze ingots, then by disks known as the ''aes rude''. The system thus named ''as'' was introduced in ca. 280 BC as a large casting (metalworking), cast bronze coin during the Roman Republic. The following fractions of the were also produced: the (), (), (), (), (), (), (, also a common weight unit), and (), as well as multiples of the ''as'', the (2), (2), and (3). After the ''as'' had been issued as a cast coin for about seventy years, and its weight had been reduced in several stages, a ''as'' was introduced (meaning that it weighed one-sixth of a pound). At about the same time a silver coin, the ''denarius'', was also introduced. Earlier Roman silver coins had been struck on the Greek weight standards that facilitated their use in sout ...

Galley
A galley is a type of ship optimised for propulsion by oars. Galleys were historically used for naval warfare, warfare, Maritime transport, trade, and piracy mostly in the seas surrounding Europe. It developed in the Mediterranean world during Classical antiquity, antiquity and continued to exist in various forms until the early 19th century. It typically had a long, slender hull, shallow draft (hull), draft, and often a low freeboard (nautical), freeboard. Most types of galleys also had sails that could be used in favourable winds, but they relied primarily on oars to move independently of winds and currents or in battle. The term "galley" originated from a Greek term for a small type of galley and came in use in English from about 1300. It has occasionally been used for unrelated vessels with similar military functions as galley but which were not Mediterranean in origin, such as medieval Scandinavian longships, 16th-century Ghali (ship), Acehnese ghalis and 18th-century North ...

Roman Empire
The Roman Empire ruled the Mediterranean and much of Europe, Western Asia and North Africa. The Roman people, Romans conquered most of this during the Roman Republic, Republic, and it was ruled by emperors following Octavian's assumption of effective sole rule in 27 BC. The Western Roman Empire, western empire collapsed in 476 AD, but the Byzantine Empire, eastern empire lasted until the fall of Constantinople in 1453. By 100 BC, the city of Rome had expanded its rule from the Italian peninsula to most of the Mediterranean Sea, Mediterranean and beyond. However, it was severely destabilised by List of Roman civil wars and revolts, civil wars and political conflicts, which culminated in the Wars of Augustus, victory of Octavian over Mark Antony and Cleopatra at the Battle of Actium in 31 BC, and the subsequent conquest of the Ptolemaic Kingdom in Egypt. In 27 BC, the Roman Senate granted Octavian overarching military power () and the new title of ''Augustus (title), Augustus'' ...

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon). These additions produce a range of alloys some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability. The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Casting (metalworking)
In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a Mold (manufacturing), mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a Sprue (manufacturing), sprue. The metal and mold are then cooled, and the metal part (the ''casting'') is extracted. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods. Casting processes have been known for thousands of years, and have been widely used for sculpture (especially in bronze), jewelry in precious metals, and weapons and tools. Highly engineered castings are found in 90 percent of durable goods, including cars, trucks, aerospace, trains, mining and construction equipment, oil wells, appliances, pipes, hydrants, wind turbines, nuclear plants, medical devices, defense products, toys, an ...

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. Roman society at the time was primarily a cultural mix of Latins (Italic tribe), Latin and Etruscan civilization, Etruscan societies, as well as of Sabine, Oscan, and Greek cultural elements, which is especially visible in the Ancient Roman religion and List of Roman deities, its pantheon. 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. There were annual elections, but the republican system was an elective olig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Janus (mythology)
In ancient Roman religion and myth, Janus ( ; ) is the god of beginnings, gates, transitions, time, duality, doorways, passages, frames, and endings. He is usually depicted as having two faces. The month of January is named for Janus (''Ianuarius''). According to ancient Roman farmers' almanacs, Juno was mistaken as the tutelary deity of the month of January, but Juno is the tutelary deity of the month of June. Janus presided over the beginning and ending of conflict, and hence war and peace. The gates of the Temple of Janus in Rome were opened in time of war and closed to mark the arrival of peace. As a god of transitions, he had functions pertaining to birth and to journeys and exchange, and in his association with Portunus, a similar harbor and gateway god, he was concerned with travelling, trading, and shipping. Janus had no flamen or specialised priest ''( sacerdos)'' assigned to him, but the King of the Sacred Rites ''(rex sacrorum)'' himself carried out his ceremon ...

Denarius
The ''denarius'' (; : ''dēnāriī'', ) was the standard Ancient Rome, Roman silver coin from its introduction in the Second Punic War to the reign of Gordian III (AD 238–244), when it was gradually replaced by the ''antoninianus''. It continued to be minted in very small quantities, likely for ceremonial purposes, until and through the Tetrarchy (293–313). The word ''dēnārius'' is derived from the Latin ''dēnī'' "containing ten", as its value was originally of 10 ''As (Roman coin), assēs''.Its value was increased to 16 assēs in the middle of the 2nd century BC. The word for "money" descends from it in Italian (''denaro''), Slovene (''denar''), Portuguese (''dinheiro''), and Spanish (''dinero''). Its name also survives in the dinar currency. Its symbol is represented in Unicode as 𐆖 (U+10196), a numeral monogram that appeared on the obverse in the Republican period, denoting the 10 ''asses'' ("X") to 1 ''denarius'' ("I") conversion rate. However it can also be re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamping (metalworking)
Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and Die (manufacturing), die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene. Progressive dies are commonly fed from a coil of steel, coil reel for unwinding of coil to a straightener to level the coil and then into a feeder which advances the material into the press and die at a predetermined feed length. Depending on part complexity, the number of stations in the die can be determined. St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punic War
The Punic Wars were a series of wars fought between the Roman Republic and the Carthaginian Empire during the period 264 to 146BC. Three such wars took place, involving a total of forty-three years of warfare on both land and sea across the western Mediterranean region, and a four-year-long revolt against Carthage. The First Punic War broke out on the Mediterranean island of Sicily in 264BC as a result of Rome's expansionary attitude combined with Carthage's proprietary approach to the island. At the start of the war Carthage was the dominant power of the western Mediterranean, with an extensive maritime empire (a thalassocracy), while Rome was a rapidly expanding power in Italy, with a strong army but no navy. The fighting took place primarily on Sicily and its surrounding waters, as well as in North Africa, Corsica and Sardinia. It lasted twenty-three years, until 241BC, when the Carthaginians were defeated. By the terms of the peace treaty Carthage paid large reparations ...
