Sestertii
The ''sestertius'' (plural ''sestertii''), or sesterce (plural 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 𐆘), in which the Roman nume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Currency
Roman currency for most of Roman history consisted of gold, silver, bronze, orichalcum and copper coinage. From its introduction to the Republic, during the third century BC, well into Imperial times, Roman currency saw many changes in form, denomination, and composition. A persistent feature was the inflationary debasement and replacement of coins over the centuries. Notable examples of this followed the reforms of Diocletian. This trend continued into Byzantine times. Due to the economic power and longevity of the Roman state, Roman currency was widely used throughout western Eurasia and northern Africa from classical times into the Middle Ages. It served as a model for the currencies of the Muslim caliphates and the European states during the Middle Ages and the Modern Era. Roman currency names survive today in many countries, such as the Arabic dinar (from the ''denarius'' coin), the British pound, and the peso (both translations of the Roman '' libra'').

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Sestertius
The double sestertius was a large Roman coin made of orichalcum (brass) first issued by Trajan Decius in AD 249–251, 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. The new coin fell out of use but was revived by the rebel emperor Postumus (259–268), 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, probably because of a shortage of metal. After his reign, the Roman coinage system degenerated further with almost the only circulating pieces being very deb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general " copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliny The Elder
Gaius Plinius Secundus (AD 23/2479), called Pliny the Elder (), was a Roman author, naturalist and natural philosopher, and naval and army commander of the early Roman Empire, and a friend of the emperor Vespasian. He wrote the encyclopedic '' Naturalis Historia'' (''Natural History''), which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. His nephew, Pliny the Younger, wrote of him in a letter to the historian Tacitus: Among Pliny's greatest works was the twenty-volume work ''Bella Germaniae'' ("The History of the German Wars"), which is no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus and Suetonius. Tacitus—who many scholars agree had never travelled in Germania—used ''Bella Germa ... [...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 (c. 0.5 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 of reddish copper. However, some dupondii wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc 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.The elements are from different metal groups. See periodic table. 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 ...

Lead
Lead is a chemical element with the Symbol (chemistry), symbol Pb (from the Latin ) and atomic number 82. It is a heavy metals, heavy metal that is density, denser than most common materials. Lead is Mohs scale of mineral hardness#Intermediate hardness, soft and 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 toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioscuri
Castor; grc, Κάστωρ, Kástōr, beaver. and Pollux. (or Polydeukes). are twin half-brothers in Greek and Roman mythology, known together as the Dioscuri.; grc, Διόσκουροι, Dióskouroi, sons of Zeus, links=no, from ''Dîos'' ('Zeus') and '' koûroi'' ('boys'). Their mother was 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 raped 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 (literally "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. The pair were regarded ...

Hostilian
Hostilian ( la, Gaius Valens Hostilianus Messius Quintus; died 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
