Ases
The ' (plural '), occasionally ''assarius'' (plural ''assarii'', rendered into Greek as , ''assárion'') 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 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 ...

Roman Empire
The Roman Empire ( la, Imperium Romanum ; grc-gre, Βασιλεία τῶν Ῥωμαίων, Basileía tôn Rhōmaíōn) was the post-Republican period of ancient Rome. As a polity, it included large territorial holdings around the Mediterranean Sea in Europe, North Africa, and Western Asia, and was ruled by emperors. From the accession of Caesar Augustus as the first Roman emperor to the military anarchy of the 3rd century, it was a Principate with Italia as the metropole of its provinces and the city of Rome as its sole capital. The Empire was later ruled by multiple emperors who shared control over the Western Roman Empire and the Eastern Roman Empire. The city of Rome remained the nominal capital of both parts until AD 476 when the imperial insignia were sent to Constantinople following the capture of the Western capital of Ravenna by the Germanic barbarians. The adoption of Christianity as the state church of the Roman Empire in AD 380 and the fall of the Western ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galley
A galley is a type of ship that is propelled mainly by oars. The galley is characterized by its long, slender hull, shallow draft, and low freeboard (clearance between sea and gunwale). Virtually all types of galleys had sails that could be used in favorable winds, but human effort was always the primary method of propulsion. This allowed galleys to navigate independently of winds and currents. The galley originated among the seafaring civilizations around the Mediterranean Sea in the late second millennium BC and remained in use in various forms until the early 19th century in warfare, trade, and piracy. Galleys were the warships used by the early Mediterranean naval powers, including the Greeks, Illyrians, Phoenicians, and Romans. They remained the dominant types of vessels used for war and piracy in the Mediterranean Sea until the last decades of the 16th century. As warships, galleys carried various types of weapons throughout their long existence, including rams, catapults ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casting (metalworking)
In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a 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. 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, and more. Traditional techniques include lost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 that may be harder than copper alone, or have other useful properties, such as ultimate tensile strength, strength, ductility, or machinability. The three-age system, archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia and India 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 starting from 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 mod ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) 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 metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

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 ...

Clarendon Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 500 years, OUP has primarily focused on the publication of pedagogical texts and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Janus (mythology)
In ancient Roman religion and myth, Janus ( ; la, Ianvs ) 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 a building in Rome named after him (not a temple, as it is often called, but an open enclosure with gates at each end) 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)'' a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadrans
The quadrans (literally meaning "a quarter") or teruncius ("three unciae") was a low-value Roman bronze coin worth one quarter of an as. The quadrans was issued from the beginning of cast bronze coins during the Roman Republic with three pellets representing three unciae as a mark of value. The obverse type, after some early variations, featured the bust of Hercules, while the reverse featured the prow of a galley. Coins with the same value were issued from other cities in Central Italy, using a cast process. After ca. 90 BC, when bronze coinage was reduced to the semuncial standard, the quadrans became the lowest-valued coin in production. Surviving 'quadrans' from this period (though that name is not shown on the coins) typically have weights between 1.5 grams and 4 grams, perhaps depending in part on the alloy or metals contained. It was produced sporadically until the time of Antoninus Pius (AD 138–161). Unlike other coins during the Roman Empire, the quadrans rarely ...

Denarius
The denarius (, dēnāriī ) was the standard 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 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 represented as X̶ (capital letter X with combining long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punic War
The Punic Wars were a series of wars between 264 and 146BC fought between Rome and Carthage. Three conflicts between these states took place on both land and sea across the western Mediterranean region and involved a total of forty-three years of warfare. The Punic Wars are also considered to include the four-year-long revolt against Carthage which started in 241BC. Each war involved immense materiel and human losses on both sides. 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, 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 23 years, until 241BC, when the Ca ...
