Tetarteron
The ''tetarteron'' ( el, όμισματεταρτηρόν, "quarter oin) was a Byzantine term applied to two different coins, one gold circulating from the 960s to 1092 in parallel to the ''histamenon'', and one copper used from 1092 to the second half of the 13th century. Gold coin Ever since Emperor Constantine I (r. 306–337), the Byzantine Empire's main coinage had been the high-quality ''solidus'' or ''nomisma'', which had remained standard in weight and gold content through the centuries. The Emperor Nikephoros II Phokas (r. 963–969), however, introduced a new coin which was a 2 carats (i.e. about 1⁄12, despite its name) lighter than the original ''nomisma'', which now became known as the ''histamenon''... The exact reason for the introduction of the ''tetarteron'' is unclear. According to the historian Zonaras, this was done to increase state revenues: the taxes were to be paid as before in the ''histamenon'', while the state paid its own expenses in the less valuabl ...

Histamenon
''Histamenon'' ( grc-gre, όμισμαἱστάμενον '' ómismahistámenon'', "standard oin) was the name given to the gold Byzantine ''solidus'' when the slightly lighter ''tetarteron'' was introduced in the 960s. To distinguish the two, the ''histamenon'' was changed in form from the original ''solidus'', becoming wider and thinner, as well as concave (scyphate) in form. Later usually shortened to ''stamenon'' (Greek: στάμενον), it was discontinued after 1092. In the 12th and 13th centuries, the name ''stamenon'' came to be applied to the concave billon and copper ''trachea'' coins. Establishment Ever since Emperor Constantine I () introduced it in 309, the Byzantine Empire's main coinage had been the high-quality ''solidus'' or ''nomisma'', which had remained standard in weight (4.55 grams) and gold content (24 carats) through the centuries.

Byzantine Coinage
Byzantine currency, money used in the Eastern Roman Empire after the fall of the West, consisted of mainly two types of coins: the gold solidus and a variety of clearly valued bronze coins. By the end of the empire the currency was issued only in silver stavrata and minor copper coins with no gold issue. The East Roman or Byzantine Empire established and operated several mints throughout its history. Aside from the main metropolitan mint in the capital, Constantinople, a varying number of provincial mints were also established in other urban centres, especially during the 6th century. Most provincial mints except for Syracuse were closed or lost to invasions by the mid-7th century. After the loss of Syracuse in 878, Constantinople became the sole mint for gold and silver coinage until the late 11th century, when major provincial mints began to re-appear. Many mints, both imperial and, as the Byzantine world fragmented, belonging to autonomous local rulers, were operated in the ...

Solidus (coin)
The ''solidus'' (Latin 'solid'; ''solidi'') or nomisma ( grc-gre, νόμισμα, ''nómisma'', 'coin') was a highly pure gold coin issued in the Late Roman Empire and Byzantine Empire. Constantine I, Constantine introduced the coin, and its weight of about 4.5 grams remained relatively constant for seven centuries. In the Byzantine Empire, the solidus or nomisma remained a highly pure gold coin until the 11th century, when several Byzantine Empire, Byzantine list of Byzantine emperors, emperors began to strike the coin with less and less gold. The nomisma was finally abolished by Alexius I in 1092, who replaced it with the hyperpyron, which also came to be known as a "bezant". The Byzantine solidus also inspired the originally slightly less pure Dinar (coin), dinar issued by the Muslim Caliphate. In Western Europe, the solidus was the main gold coin of commerce from late Roman times to Pepin the Short's Carolingian Renaissance#Carolingian currency, currency reform, wh ...

Alexios I Komnenos
Alexios I Komnenos ( grc-gre, Ἀλέξιος Κομνηνός, 1057 – 15 August 1118; Latinized Alexius I Comnenus) was Byzantine emperor from 1081 to 1118. Although he was not the first emperor of the Komnenian dynasty, it was during his reign that the Komnenos family came to full power and initiated a hereditary succession to the throne. Inheriting a collapsing empire and faced with constant warfare during his reign against both the Seljuq Turks in Asia Minor and the Normans in the western Balkans, Alexios was able to curb the Byzantine decline and begin the military, financial, and territorial recovery known as the Komnenian restoration. His appeals to Western Europe for help against the Turks was the catalyst that sparked the First Crusade. Biography Alexios was the son of John Komnenos and Anna Dalassene,Kazhdan 1991, p. 63 and the nephew of Isaac I Komnenos (emperor 1057–1059). Alexios' father declined the throne on the abdication of Isaac, who was thu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperpyron
The ''hyperpyron'' ( ''nómisma hypérpyron'') was a Byzantine coin in use during the late Middle Ages, replacing the ''solidus'' as the Byzantine Empire's gold coinage. History The traditional gold currency of the Byzantine Empire had been the ''solidus'' or ''nomisma'', whose gold content had remained steady at 24 carats for seven centuries and was consequently highly prized. From the 1030s, however, the coin was increasingly debased, until in the 1080s, following the military disasters and civil wars of the previous decade, its gold content was reduced to almost zero. Consequently, in 1092, Emperor Alexios I Komnenos ( 1081–1118) undertook a drastic overhaul of the Byzantine coinage system and introduced a new gold coin, the ''hyperpyron'' (meaning "super-refined"). This was of the same standard weight (4.45 grams) as the ''solidus'', but only 20.5 carat purity instead of 24, resulting in a reduced gold content of only 4.1 grams instead of 4.8 grams. The lower purity was due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byzantine Empire
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome ...

Michael IV The Paphlagonian
Michael IV the Paphlagonian ( el, , ''Mikhaēl ho Paphlagōn''; c. 1010 – 10 December 1041) was Byzantine Emperor from 11 April 1034 to his death on 10 December 1041. The son of a peasant, Michael worked as a money changer until he was found a job at court by his brother John the Orphanotrophos. He caught the eye of the empress Zoë Porphyrogenita and they began a tempestuous and flagrant affair. It is believed that they conspired to murder her husband, Emperor Romanos III Argyros, who died in 1034. Michael and Zoë were married the same day and Michael was crowned emperor the day after. Michael, handsome and energetic, had poor health and entrusted most of the business of government to his brother. He distrusted Zoë and went to lengths to ensure that he did not suffer the same fate as his predecessor. The fortunes of the Empire under Michael's reign were mixed. His most triumphant moment came in 1041 when he led the imperial army against Bulgarian rebels. He returned from ... [...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'').

Assarion
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 ...
