Roman currency

The manufacture of coins in the Roman culture, dating from about the 4th century BC, significantly influenced later development of coin minting in Europe. The origin of the word "mint" is ascribed to the manufacture of silver coin at Rome in 269 BC near the temple of Juno Moneta. This goddess became the personification of money, and her name was applied both to money and to its place of manufacture. Roman mints were spread widely across the Empire, and were sometimes used for propaganda purposes. The populace often learned of a new Roman Emperor when coins appeared with the new emperor's portrait. Some of the emperors who ruled only for a short time made sure that a coin bore their image; Quietus, for example, ruled only part of the Roman Empire from 260 to 261 AD, and yet he issued thirteen coins bearing his image from three mints.^[2] The Romans cast their larger copper coins in clay moulds carrying distinctive markings, not because they did not know about striking, but because it was not suitable for such large masses of metal.

Roman adoption of metallic commodity money was a late development in monetary history. Bullion bars and ingots were used as money in Mesopotamia since the 7th millennium BC; and Greeks in Asia Minor had pioneered the use of coinage (which they employed in addition to other more primitive, monetary mediums of exchange) as early as the 7th century BC.^[3]

Bronze aes signatum produced by the Roman Republic after 450 BC

Coinage proper was only introduced by the republican government c. 300 BC. The greatest city of the Magna Graecia region in southern Italy, and several other Italian cities, already had a long tradition of using coinage by this time and produced them in large quantities during the 4th century BC to pay for their wars against the inland Italian groups encroaching on their territory. For these reasons, the Romans would have certainly known about coinage systems long before their government actually introduced them. Eventually, the economic conditions of the Second Punic War forced the Romans to fully adopt a coinage system.^[4]

The type of money introduced by Rome was unlike that found elsewhere in the ancient Mediterranean. It combined a number of uncommon elements. One example is the large bronze bullion, the aes signatum (Latin for signed bronze). It measured about 16 by 9 centimetres (6.3 by 3.5 in) and weighed around 1.5 to 1.6 kilograms (3.3 to 3.5 lb), being made out of a highly leaded tin bronze. Although similar metal currency bars had been produced in Italy and northern Etruscan areas, these had been made of aes grave, an unrefined metal with a high iron content.^[5]

Along with the aes signatum, the Roman state also issued a series of bronze and silver coins that emulated the styles of those produced in Greek cities.^[6] Produced using the manner of manufacture then utilised in Greek Naples, the designs of these early coins were also heavily influenced by Greek designs.^[7]

The designs on the coinage of the Republican period displayed a "solid conservatism", usually illustrating mythical scenes or personifications of various gods and goddesses.^[8]

Roman Republican currency

Roman Republican currency

Roman Republican currency refers to the coinage struck by the various magistrates of the Roman Republic, to be used as legal tender. In modern times, the abbreviation RRC, "Roman Republican Coinage" originally the name of a reference work on the topic by Michael H. Crawford, has come to be used as an identifying tag for coins assigned a number in that work, such as RRC 367.

Commodity money

Commodity money

Commodity money is money whose value comes from a commodity of which it is made. Commodity money consists of objects having value or use in themselves as well as their value in buying goods. This is in contrast to representative money, which has no intrinsic value but represents something of value such as gold or silver, in which it can be exchanged, and fiat money, which derives its value from having been established as money by government regulation.

History of money

History of money

The history of money concerns the development throughout time of systems that provide the functions of money. Such systems can be understood as means of trading wealth indirectly; not directly as with bartering. Money is a mechanism that facilitates this process.

Bullion

Bullion

Bullion is non-ferrous metal that has been refined to a high standard of elemental purity. The term is ordinarily applied to bulk metal used in the production of coins and especially to precious metals such as gold and silver. It comes from the Anglo-Norman term for a melting-house where metal was refined, and earlier from French bouillon, "boiling". Although precious metal bullion is no longer used to make coins for general circulation, it continues to be held as an investment with a reputation for stability in periods of economic uncertainty. To assess the purity of gold bullion, the centuries-old technique of fire assay is still employed, together with modern spectroscopic instrumentation, to accurately determine its quality.

Aes signatum

Aes signatum

Aes signatum consisted of cast ingots of bronze of measured quality and weight, embossed with a government stamp, used as currency in Rome and central Italy starting in the 5th century BCE before the introduction of aes grave in the mid 3rd century BCE. When exactly they were first made is uncertain. Popular tradition ascribes them to Servius Tullius, but due to the high quality of art found on even the earliest specimens, this seems very unlikely. A date in the midst of the 5th century BC is generally agreed on. Designs featured are that of a bull, an eagle, and other religious symbols.

Magna Graecia

Magna Graecia

Magna Graecia was the name given by the Romans to the coastal areas of Southern Italy in the present-day Italian regions of Calabria, Apulia, Basilicata, Campania and Sicily; these regions were extensively populated by Greek settlers. These settlers, who began arriving in the 8th century BC, brought with them their Hellenic civilization, which left a lasting imprint on Italy. They also influenced the native peoples, such as the Sicels and the Oenotrians, who became hellenized after they adopted the Greek culture as their own.

Latin

Latin

Latin is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition.

Etruscan cities

Etruscan cities

Etruscan cities were a group of ancient settlements that shared a common Etruscan language and culture, even though they were independent city-states. They flourished over a large part of the northern half of Italy starting from the Iron Age, and in some cases reached a substantial level of wealth and power. They were eventually assimilated first by Italics in the south, then by Celts in the north and finally in Etruria itself by the growing Roman Republic.

Aes grave

Aes grave

Aes grave is a term in numismatics indicating bronze cast coins used in central Italy during the 3rd century BC, whose value was generally indicated by signs: I for the as, S for semis and pellets for unciae. Standard weights for the as were 272, 327, or 341 grams, depending upon the issuing authority.

Ancient Greek coinage

Ancient Greek coinage

The history of ancient Greek coinage can be divided into four periods: the Archaic, the Classical, the Hellenistic and the Roman. The Archaic period extends from the introduction of coinage to the Greek world during the 7th century BC until the Persian Wars in about 480 BC. The Classical period then began, and lasted until the conquests of Alexander the Great in about 330 BC, which began the Hellenistic period, extending until the Roman absorption of the Greek world in the 1st century BC. The Greek cities continued to produce their own coins for several more centuries under Roman rule. The coins produced during this period are called Roman provincial coins or Greek Imperial Coins.

Iconography

The imagery on coins took an important step when Julius Caesar issued coins bearing his own portrait. While moneyers had earlier issued coins with portraits of ancestors, Caesar's was the third Roman coinage to feature the depiction of a living individual. Although living Romans had appeared on coinage before,^[9] in the words of Clare Rowan (2019) "The appearance of Caesar's portrait on Roman denarii in 44 BC is often seen as a revolutionary moment in Roman history..."^[10] The appearance of Julius Caesar implemented a new standard, and the tradition continued following Caesar's assassination, although the Roman emperors from time to time also produced coins featuring the traditional deities and personifications found on earlier coins. The image of the emperor took on a special importance in the centuries that followed, because during the Empire the emperor embodied the state and its policies. The names of moneyers continued to appear on the coins until the middle of Augustus' reign. Although the duty of moneyers during the Empire is not known, since the position was not abolished, it is believed that they still had some influence over the imagery of the coins.

The main focus of the imagery during the Empire was on the portrait of the emperor. Coins were an important means of disseminating this image throughout the Empire. Coins often attempted to make the emperor appear god-like through associating the emperor with attributes normally seen in divinities, or emphasizing the special relationship between the emperor and a particular deity by producing a preponderance of coins depicting that deity. During his campaign against Pompey, Caesar issued a variety of types that featured images of either Venus or Aeneas, attempting to associate himself with his divine ancestors. An example of an emperor who went to an extreme in proclaiming divine status was Commodus. In AD 192, he issued a series of coins depicting his bust clad in a lion-skin (the usual depiction of Hercules) on the obverse, and an inscription proclaiming that he was the Roman incarnation of Hercules on the reverse. Although Commodus was excessive in his depiction of his image, this extreme case is indicative of the objective of many emperors in the exploitation of their portraits. While the emperor is by far the most frequent portrait on the obverse of coins, heirs apparent, predecessors, and other family members, such as empresses, were also featured. To aid in succession, the legitimacy of an heir was affirmed by producing coins for that successor. This was done from the time of Augustus till the end of the Empire.

Coins of the Roman Republic and Empire from Cassell's History of England, Vol. I

Featuring the portrait of an individual on a coin, which became legal in 44 BC, caused the coin to be viewed as embodying the attributes of the individual portrayed. Cassius Dio wrote that following the death of Caligula the Senate demonetized his coinage and ordered that they be melted. Regardless of whether or not this actually occurred, it demonstrates the importance and meaning that was attached to the imagery on a coin. The philosopher Epictetus jokingly wrote: "Whose image does this sestertius carry? Trajan's? Give it to me. Nero's? Throw it away, it is unacceptable, it is rotten." Although the writer did not seriously expect people to get rid of their coins, this quotation demonstrates that the Romans attached a moral value to the images on their coins. Unlike the obverse, which during the Imperial period almost always featured a portrait, the reverse was far more varied in its depiction. During the late Republic there were often political messages to the imagery, especially during the periods of civil war. However, by the middle of the Empire, although there were types that made important statements, and some that were overtly political or propagandistic in nature, the majority of the types were stock images of personifications or deities. While some images can be related to the policy or actions of a particular emperor, many of the choices seem arbitrary and the personifications and deities were so prosaic that their names were often omitted, as they were readily recognizable by their appearance and attributes alone.

It can be argued that within this backdrop of mostly indistinguishable types, exceptions would be far more pronounced. Atypical reverses are usually seen during and after periods of war, at which time emperors make various claims of liberation, subjugation, and pacification. Some of these reverse images can clearly be classified as propaganda. An example struck by emperor Philip the Arab in 244 features a legend proclaiming the establishment of peace with Persia; in truth, Rome had been forced to pay large sums in tribute to the Persians.

Although it is difficult to make accurate generalizations about reverse imagery, as this was something that varied by emperor, some trends do exist. An example is reverse types of the military emperors during the second half of the third century, where virtually all of the types were the common and standard personifications and deities. A possible explanation for the lack of originality is that these emperors were attempting to present conservative images to establish their legitimacy, something that many of these emperors lacked. Although these emperors relied on traditional reverse types, their portraits often emphasized their authority through stern gazes,^[11] and even featured the bust of the emperor clad in armor.^[12]

Julius Caesar

Julius Caesar

Gaius Julius Caesar was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in a civil war, and subsequently became dictator from 49 BC until his assassination in 44 BC. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire.

Assassination of Julius Caesar

Assassination of Julius Caesar

Julius Caesar, was assassinated by a group of senators on the Ides of March of 44 BC during a meeting of the Senate at the Curia of Pompey of the Theatre of Pompey in Rome where the senators stabbed Caesar 23 times. They claimed to be acting over fears that Caesar's unprecedented concentration of power during his dictatorship was undermining the Roman Republic. At least 60 to 70 senators were party to the conspiracy, led by Marcus Junius Brutus, Gaius Cassius Longinus, and Decimus Junius Brutus Albinus. Despite the death of Caesar, the conspirators were unable to restore the institutions of the Republic. The ramifications of the assassination led to the Liberators' civil war and ultimately to the Principate period of the Roman Empire.

Roman emperor

Roman emperor

The Roman emperor was the ruler and monarchial head of state of the Roman Empire during the imperial period. The emperors used a variety of different titles throughout history. Often when a given Roman is described as becoming "emperor" in English it reflects his taking of the title augustus. Another title often used was caesar, used for heirs-apparent, and imperator, originally a military honorific. Early emperors also used the title princeps civitatis. Emperors frequently amassed republican titles, notably princeps senatus, consul, and pontifex maximus.

Augustus

Augustus

Caesar Augustus, also known as Octavian, was the first Roman emperor; he reigned from 27 BC until his death in AD 14. He is known for being the founder of the Roman Principate, which is the first phase of the Roman Empire, and is considered one of the greatest leaders in human history. The reign of Augustus initiated an imperial cult as well as an era associated with imperial peace, the Pax Romana or Pax Augusta. The Roman world was largely free from large-scale conflict for more than two centuries despite continuous wars of imperial expansion on the empire's frontiers and the year-long civil war known as the "Year of the Four Emperors" over the imperial succession.

Pompey

Pompey

Gnaeus Pompeius Magnus, known in English as Pompey or Pompey the Great, was a leading Roman general and statesman. He played a significant role in the transformation of Rome from republic to empire. Early in his career, he was a partisan and protégé of the Roman general and dictator Sulla; later, he became the political ally, and finally the enemy, of Julius Caesar.

Aeneas

Aeneas

In Greco-Roman mythology, Aeneas was a Trojan hero, the son of the Dardanian prince Anchises and the Greek goddess Aphrodite. His father was a first cousin of King Priam of Troy, making Aeneas a second cousin to Priam's children. He is a minor character in Greek mythology and is mentioned in Homer's Iliad. Aeneas receives full treatment in Roman mythology, most extensively in Virgil's Aeneid, where he is cast as an ancestor of Romulus and Remus. He became the first true hero of Rome. Snorri Sturluson identifies him with the Norse god Vidarr of the Æsir.

Commodus

Commodus

Commodus was a Roman emperor who ruled from 177 to 192. He served jointly with his father Marcus Aurelius from 177 until the latter's death in 180, and thereafter he reigned alone until his assassination. His reign is commonly thought of as marking the end of a golden age of peace and prosperity in the history of the Roman Empire, known as the Pax Romana.

Hercules

Hercules

Hercules is the Roman equivalent of the Greek divine hero Heracles, son of Jupiter and the mortal Alcmena. In classical mythology, Hercules is famous for his strength and for his numerous far-ranging adventures.

Cassius Dio

Cassius Dio

Lucius Cassius Dio, also known as Dio Cassius, was a Roman historian and senator of maternal Greek origin. He published 80 volumes of the history on ancient Rome, beginning with the arrival of Aeneas in Italy. The volumes documented the subsequent founding of Rome, the formation of the Republic, and the creation of the Empire, up until 229 AD. Written in Ancient Greek over 22 years, Dio's work covers approximately 1,000 years of history. Many of his 80 books have survived intact, or as fragments, providing modern scholars with a detailed perspective on Roman history.

Caligula

Caligula

Caligula, formally known as Gaius, was the third Roman emperor, ruling from AD 37 until his assassination in AD 41. He was the son of the Roman general Germanicus and Agrippina the Elder, Augustus' granddaughter. Caligula was born into the first ruling family of the Roman Empire, conventionally known as the Julio-Claudian dynasty.

Epictetus

Epictetus

Epictetus was a Greek Stoic philosopher. He was born into slavery at Hierapolis, Phrygia and lived in Rome until his banishment, when he went to Nicopolis in northwestern Greece for the rest of his life. His teachings were written down and published by his pupil Arrian in his Discourses and Enchiridion.

Philip the Arab

Philip the Arab

Philip the Arab was Roman emperor from 244 to 249. He was born in Aurantis, Arabia, in a city situated in modern-day Syria. After the death of Gordian III in February 244, Philip, who had been Praetorian prefect, achieved power. He quickly negotiated peace with the Persian Sassanid Empire and returned to Rome to be confirmed by the Senate. During his reign, the city of Rome celebrated its millennium.

Unlike most modern coins, Roman coins had (at least in the early centuries) significant intrinsic value. However, while the gold and silver issues contained precious metals, the value of a coin could be slightly higher than its precious metal content, so they were not, strictly speaking, equivalent to bullion. Also, over the course of time the purity and weight of the silver coins were reduced. Estimates of the value of the denarius range from 1.6 to 2.85 times its metal content, thought to equal the purchasing power of 10 modern British pound sterling at the beginning of the Roman Empire to around 18 pound sterling by its end (comparing bread, wine, and meat prices) and, over the same period, around one to three days' pay for a legionary.^[13]

The coinage system that existed in Egypt until the time of Diocletian's monetary reform was a closed system based upon the heavily debased tetradrachm. Although the value of these tetradrachms can be reckoned as being equivalent to that of the denarius, their precious metal content was always much lower. Elsewhere also, not all coins that circulated contained precious metals, as the value of these coins was too great to be convenient for everyday purchases. A dichotomy existed between the coins with an intrinsic value and those with only a token value. This is reflected in the infrequent and inadequate production of bronze coinage during the Republic, where from the time of Sulla till the time of Augustus no bronze coins were minted at all; even during the periods when bronze coins were produced, their workmanship was sometimes very crude and of low quality.

Debasement

The rapid decline in silver purity of the antoninianus

The type of coins issued changed under the coinage reform of Diocletian, the heavily debased antoninianus (double denarius) was replaced with a variety of new denominations, and a new range of imagery was introduced that attempted to convey different ideas. The new government set up by Diocletian was a Tetrarchy, or rule by four, with each emperor receiving a separate territory to rule.

The new imagery includes a large, stern portrait that is representative of the emperor. This image was not meant to show the actual portrait of a particular emperor, but was instead a character that embodied the power that the emperor possessed. The reverse type was equally universal, featuring the spirit (or genius) of the Romans. The introduction of a new type of government and a new system of coinage represents an attempt by Diocletian to return peace and security to Rome, after the previous century of constant warfare and uncertainty. Diocletian characterizes the emperor as an interchangeable authority figure by depicting him with a generalized image. He tries to emphasize unity amongst the Romans by featuring the spirit of Romans (Sutherland 254). The reverse types of coins of the late Empire emphasized general themes, and discontinued the more specific personifications depicted previously. The reverse types featured legends that proclaimed the glory of Rome, the glory of the Roman army, victory against the "barbarians", the restoration of happy times, and the greatness of the emperor.

These general types persisted even after the adoption of Christianity as the state religion of the Roman Empire. Muted Christian imagery, such as standards that featured Christograms (the Chi Rho monogram for Jesus Christ's name in Greek) were introduced, but with a few rare exceptions, there were no explicitly Christian themes. From the time of Constantine the Great until the "end" of the Roman Empire, coins featured almost indistinguishable idealized portraits and general proclamations of greatness.

Although the denarius remained the backbone of the Roman economy from its introduction a few years before 211 BC until it ceased to be normally minted in the middle of the third century, the purity and weight of the coin slowly, but inexorably, decreased. The problem of debasement in the Roman economy appears to be pervasive, although the severity of the debasement often paralleled the strength or weakness of the Empire. While it is not clear why debasement became such a common occurrence for the Romans, it's believed that it was caused by several factors, including a lack of precious metals and inadequacies in state finances. When introduced, the denarius contained nearly pure silver at a theoretical weight of approximately 4.5 grams, but from the time of Nero onwards the tendency was nearly always for its purity to be decreased.

The theoretical standard, although not usually met in practice, remained fairly stable throughout the Republic, with the notable exception of times of war. The large number of coins required to raise an army and pay for supplies often necessitated the debasement of the coinage. An example of this is the denarii that were struck by Mark Antony to pay his army during his battles against Octavian. These coins, slightly smaller in diameter than a normal denarius, were made of noticeably debased silver. The obverse features a galley and the name Antony, while the reverse features the name of the particular legion that each issue was intended for (hoard evidence shows that these coins remained in circulation over 200 years after they were minted, due to their lower silver content). The coinage of the Julio-Claudians remained stable at 4 grams of silver, until the debasement of Nero in 64, when the silver content was reduced to 3.8 grams, perhaps due to the cost of rebuilding the city after fire consumed a considerable portion of Rome.

The denarius continued to decline slowly in purity, with a notable reduction instituted by Septimius Severus. This was followed by the introduction of a double denarius piece, differentiated from the denarius by the radiate crown worn by the emperor. The coin is commonly called the antoninianus by numismatists after the emperor Caracalla, who introduced the coin in early 215. Although nominally valued at two denarii, the antoninianus never contained more than 1.6 times the amount of silver of the denarius. The profit of minting a coin valued at two denarii, but weighing only about one and a half times as much is obvious; the reaction to these coins by the public is unknown. As the number of antoniniani minted increased, the number of denarii minted decreased, until the denarius ceased to be minted in significant quantities by the middle of the third century. Again, coinage saw its greatest debasement during times of war and uncertainty. The second half of the third century was rife with this war and uncertainty, and the silver content of the antonianus fell to only 2%, losing almost any appearance of being silver. During this time the aureus remained slightly more stable, before it too became smaller and more base (lower gold content and higher base metal content) before Diocletian's reform.

The decline in the silver content to the point where coins contained virtually no silver at all was countered by the monetary reform of Aurelian in 274. The standard for silver in the antonianus was set at twenty parts copper to one part silver, and the coins were noticeably marked as containing that amount (XXI in Latin or KA in Greek). Despite the reform of Aurelian, silver content continued to decline, until the monetary reform of Diocletian. In addition to establishing the Tetrarchy, Diocletian devised the following system of denominations: an aureus struck at the standard of 60 to the pound, a new silver coin struck at the old Neronian standard known as the argenteus, and a new large bronze coin that contained two percent silver.

Diocletian issued an Edict on Maximum Prices in 301, which attempted to establish the legal maximum prices that could be charged for goods and services. The attempt to establish maximum prices was an exercise in futility as maximum prices were impossible to enforce. The Edict was reckoned in terms of denarii, although no such coin had been struck for over 50 years (it is believed that the bronze follis was valued at 12+1⁄2 denarii). Like earlier reforms, this too eroded and was replaced by an uncertain coinage consisting mostly of gold and bronze. The exact relationship and denomination of the bronze issues of a variety of sizes is not known, and is believed to have fluctuated heavily on the market.

The exact reason that Roman coinage sustained continuous debasement is not known, but the most common theories involve inflation, trade with India (which drained silver from the Mediterranean world) and inadequacies in state finances. It is clear from papyri that the pay of the Roman soldier increased from 900 sestertii a year under Augustus to 2,000 sestertii a year under Septimius Severus, while the price of grain more than tripled, indicating a fall in real wages and moderate inflation during this time.^[14]

Denarius

The denarius was the standard Roman silver coin from its introduction in the Second Punic War c. 211 BC to the reign of Gordian III, 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).

Legionary

The Roman legionary was a professional heavy infantryman of the Roman army after the Marian reforms. These soldiers would conquer and defend the territories of ancient Rome during the late Republic and Principate eras, alongside auxiliary and cavalry detachments.

The antoninianus or pre-reform radiate, was a coin used during the Roman Empire thought to have been valued at 2 denarii. It was initially silver, but was slowly debased to bronze with a minimal silver content. The coin was introduced by Caracalla in early 215 AD. It was silver, similar to the denarius except that it was slightly larger and featured the emperor wearing a radiate crown, indicating it was a double denomination. Antoniniani depicting women featured the bust resting upon a crescent moon.

Diocletian

Diocletian

Diocletian, nicknamed "Jovius", was Roman emperor from 284 until his abdication in 305. He was born Diocles to a family of low status in the Roman province of Dalmatia. Diocles rose through the ranks of the military early in his career, eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name Diocletianus. The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.

Constantine the Great

Constantine the Great

Constantine I, also known as Constantine the Great, was Roman emperor from AD 306 to 337, the first one to convert to Christianity. Born in Naissus, Dacia Mediterranea, he was the son of Flavius Constantius, a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy. His mother, Helena, was a Greek Christian of low birth. Later canonized as a saint, she is traditionally attributed with the conversion of her son. Constantine served with distinction under the Roman emperors Diocletian and Galerius. He began his career by campaigning in the eastern provinces before being recalled in the west to fight alongside his father in Britain. After his father's death in 306, Constantine became emperor. He was acclaimed by his army at Eboracum, and eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324.
