The ''sestertius'' (: ''sestertii'') or sesterce (: sesterces) was an ancient Roman coin. During the Roman Republic it was a small, silver coin issued only on rare occasions. During the Roman Empire it was a large brass coin. The name ''sestertius'' means "two and one half", referring to its nominal value of two and a half '' asses'' (a bronze Roman coin, singular ''as''), a value that was useful for commerce because it was one quarter of a denarius, a coin worth ten ''asses''. The name is derived from ''semis'', "half" and ''tertius'', "third", in which "third" refers to the third ''as'': the sestertius was worth two full ''asses'' and half of a third. English-language sources routinely use the original Latin form ''sestertius'', plural ''sestertii''; but older literature frequently uses ''sesterce'', plural ''sesterces'', ''terce'' being the English equivalent of ''tertius''. A modern shorthand for values in sestertii is IIS (Unicode ๐), in which the Roman numeral ''II'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dioscuri
Castor and Pollux (or Polydeuces) are twin half-brothers in Greek mythology, Greek and Roman mythology, known together as the Dioscuri or Dioskouroi. Their mother was Leda (mythology), Leda, but they had different fathers; Castor was the mortal son of Tyndareus, the king of Sparta, while Pollux was the divine son of Zeus, who seduced Leda in the guise of a swan. The pair are thus an example of heteropaternal superfecundation. Though accounts of their birth are varied, they are sometimes said to have been born from an egg, along with their twin sisters Helen of Troy and Clytemnestra. In Latin, the twins are also known as the Gemini ("twins") or Castores, as well as the Tyndaridae or Tyndarids. Pollux asked Zeus to let him share his own immortality with his twin to keep them together, and they were transformed into the constellation Gemini (constellation), Gemini. The pair were regarded as the patrons of sailors, to whom they appeared as St. Elmo's fire. They were also associated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nero
Nero Claudius Caesar Augustus Germanicus ( ; born Lucius Domitius Ahenobarbus; 15 December AD 37 โ 9 June AD 68) was a Roman emperor and the final emperor of the Julio-Claudian dynasty, reigning from AD 54 until his death in AD 68. Nero was born at Antium in AD 37, the son of Gnaeus Domitius Ahenobarbus (father of Nero), Gnaeus Domitius Ahenobarbus and Agrippina the Younger (great-granddaughter of the emperor Augustus). Nero was three when his father died. By the time Nero turned eleven, his mother married Emperor Claudius, who then Adoption in ancient Rome, adopted Nero as his heir. Upon Claudius' death in AD 54, Nero ascended to the throne with the backing of the Praetorian Guard and the Senate. In the early years of his reign, Nero was advised and guided by his mother Agrippina, his tutor Seneca the Younger, and his praetorian prefect Sextus Afranius Burrus, but sought to rule independently and rid himself of restraining influences.

Double Sestertius
The double ''sestertius'' was a large Roman coin made of orichalcum ("gold-brass") first issued by Emperor Trajan Decius in AD 249โ251, as a response to the inflationary pressures of the time which had devalued the buying power of the conventional ''sestertius''. In reality the new coin was little bigger than the traditional ''sestertius'', which by then was being manufactured at a lower weight and smaller size than it had originally been, and was not a success. Although commonly described as a "double" ''sestertius'', it was probably worth only one ''sestertius'' and a half. The new coin fell out of use but was revived by the rebel emperor Postumus (259โ268), who ruled a breakaway empire consisting of Britain, Gaul and parts of Germany, and was keen to associate his regime with a reformed coinage system. Postumus issued his own version of the double ''sestertius'', often taking very worn old ''sestertii'' and using these to overstrike his own portrait and legends on, probabl ...

Aurelian
Aurelian (; ; 9 September ) was a Roman emperor who reigned from 270 to 275 AD during the Crisis of the Third Century.

Debasement
A debasement of coinage is the practice of lowering the intrinsic value of coins, especially when used in connection with commodity money, such as gold or silver coins, while continuing to circulate it at face value. A coin is said to be debased if the quantity of gold, silver, copper or nickel in the coin is reduced. Examples Roman Empire In Roman currency, the value of the denarius was gradually decreased over time as the Ancient Rome, Roman government altered both the size and the silver content of the coin. Originally, the silver used was nearly pure, weighing about 4.5 grams. From time to time, this was reduced. During the Julio-Claudian dynasty, the denarius contained approximately 4 grams of silver, and then was reduced to 3.8 grams under Nero. The denarius continued to shrink in size and purity, until by the second half of the third century, it was only about 2% silver, and was replaced by the Argenteus.

Inflation
In economics, inflation is an increase in the average price of goods and services in terms of money. This increase is measured using a price index, typically a consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. Changes in inflation are widely attributed to fluctuations in Real versus nominal value (economics), real demand for goods and services (also known as demand shocks, including changes in fiscal policy, fiscal or monetary policy), changes in available supplies such as during energy crisis, energy crises (also known as supply shocks), or changes in inflation expectations, which may be self-fulfilling.

Hostilian
Hostilian (; died July 251) was briefly Roman emperor in 251. Hostilian was born to Decius and Herennia Etruscilla at an unknown date and elevated to ''caesar'' in 250 by Decius. After Decius and Herennius Etruscus, Hostilian's brother, were killed at the Battle of Abritus, an ambush by the Goths, Trebonianus Gallus was proclaimed emperor by the legions. Almost immediately, he elevated Hostilian to co-emperor and his own son, Volusianus, to ''caesar''. Hostilian died soon after, either due to plague or being murdered by Trebonianus Gallus. History Hostilian was born at an unknown date, to Decius, a Roman general who later became Emperor, and his wife Herennia Etruscilla. He had a brother, Herennius Etruscus, and one sister. His full name based on coinage and inscriptions was Gaius Valens Hostilianus Messius Quintus, but to this the historian Aurelius Victor adds Perpenna or Perperna, a name of Etruscan origin. In September 249 the army of Decius declared him emperor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead
Lead () is a chemical element; it has Chemical symbol, symbol Pb (from Latin ) and atomic number 82. It is a Heavy metal (elements), heavy metal that is density, denser than most common materials. Lead is Mohs scale, soft and Ductility, malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable nuclide, stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its Amphoterism, amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Lead compounds, Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited ...

Zinc
Zinc is a chemical element; it has symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the second most abundant trace metal in humans after iron, an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dupondius
The ''dupondius'' (Latin ''two-pounder'') was a brass coin used during the Roman Republic and Roman Empire valued at 2 '' asses'' (4/5 of a ''sestertius'' or 1/5 of a ''denarius'' during the Republic and 1/2 of a ''sestertius'' or 1/8 of a ''denarius'' during the time of Augustus). The ''dupondius'' was introduced during the Roman Republic as a large bronze cast coin, although even at introduction it weighed less than 2 Roman pounds (''librae''). The initial coins featured the bust of Roma on the obverse and a six-spoked wheel on the reverse. A loaf of bread or a ''sextarius'' ( L) of wine cost roughly one ''dupondius'' at the height of the Roman Empire, though due to the debasement of the ''denarius'' over the following century, the ''dupondius'' was discarded. With the coinage reform of Augustus in about 23 BC, the ''sestertius'' and ''dupondius'' were produced in a type of brass called orichalcum by the Romans and numismatists, while lower denominations were produced out ...
