Domitian Dupondius, RIC II, Part 1 (second edition) Domitian 621

Monetary Context and Denominational System

During the principate of Domitian (AD 81 to 96), the Roman monetary system maintained the bimetallic and base-metal structure established by Augustus, though subject to important fiscal reforms. Domitian enacted a major currency reform early in his reign, notably restoring the silver content of the denarius in AD 82 before slightly adjusting it in AD 85 to a standard that remained higher than that of the earlier Flavian emperors. Alongside the precious metal denominations, the base-metal coinage played an indispensable role in daily commerce throughout Italy and the western provinces. Within this framework, the dupondius represented a middle-value denomination tariffed at two asses, four semisses, or eight quadrantes, equivalent to half a sestertius or one-eighth of a silver denarius. Since the Augustan monetary reform, dupondii were struck from orichalcum, a golden-yellow alloy of copper and zinc known to the Romans as aurichalcum. To ensure immediate visual distinction between the dupondius and the similarly sized pure copper as (which was redder and slightly softer), Roman mint practice under Nero established the convention of portraying the emperor with a radiate crown on the dupondius, while the as depicted the imperial head laureate or bare. The radiate crown, traditionally linked to the solar attributes of Sol, functioned primarily as a practical denominational indicator on base-metal coinage. The production of RIC Domitian 621 in AD 88 was integrated into an exceptional celebratory emission celebrating the Ludi Saeculares, where normal base-metal production was directed toward elaborate ceremonial iconography authorized by senatorial decree, marked by the traditional formula S C (Senatus Consulto).

Production and Mint Organization

The entire special emission for the Secular Games of AD 88, including RIC Domitian 621, was struck at the imperial mint of Rome. Under the Flavians, central mint operations had been firmly consolidated in the capital following the gradual closure of western provincial mints such as Lugdunum that had been active during the civil wars of AD 68 to 69 and the early years of Vespasian. The mint of Rome possessed the technical infrastructure and master engravers capable of executing complex, multi-figure compositional dies with exceptional detail. Dupondius flans were cast in orichalcum before being hot-struck between engraved bronze or iron dies. Base-metal coinage required substantial striking pressure to fully bring up the relief of the multi-figured architectural reverse design. Mint workers, organized into specialized workshops or officinae, prepared the dies under strict state oversight. The metallurgical composition of the orichalcum dupondius during Domitian's reign typically maintained a zinc content between 10 and 20 percent, which provided the characteristic bright golden sheen upon issuance. Die axes for this issue generally conform to the standard Roman median regular alignment, predominantly oriented at 6 o'clock or 12 o'clock, reflecting careful mechanical handling by the mint staff during the intense production runs of the festival year.

Obverse Design and Portraiture

The obverse of RIC Domitian 621 displays the radiate head of Domitian facing right. Domitian's portraiture in AD 88 belongs to his mature imperial style, characterized by a heavy, square jaw, a prominent hooked nose, and carefully arranged locks of hair descending along the nape of the neck. The portrait conveys the stern, dignified gravitas that became standard in Domitianic sculpture and numismatic portraiture following his assumption of the perpetual censorship in AD 85. The radiate crown rests securely on the emperor's head, with clearly articulated triangular rays projecting outward and upward. This solar attribute had evolved from an emblem of post-mortem deification under Augustus and Tiberius into a living imperial attribute signaling the dupondius denomination since the middle of the first century AD. The die engraving exhibits exceptional technical finesse, rendering individual strands of hair, anatomical modeling of the facial muscles, and the muscular contours of the neck. Surrounding the portrait, an uninterrupted circular legend runs clockwise, tightly enclosed within a beaded border.

Reverse Iconography: The Secular Games

The reverse of RIC Domitian 621 presents an intricate multi-figure ritual composition depicting specific religious rites performed during the Secular Games. The central figure is Domitian, veiled and togate as Pontifex Maximus, standing facing left over an ignited sacrificial altar. In his right hand, the emperor holds a patera, performing a libation. Facing the emperor on the right side of the field are two sacrificial musicians: a flute player (tibicen) and a lyre player (citharoedus), both standing draped and playing their respective instruments to drown out any unpropitious sounds during the sacred rite. In the lower left foreground, beneath the altar, Father Tiber (the river god Tiberinus) reclines facing left, resting his arm upon an urn from which water flows, symbolizing the location of the games along the banks of the river at the Campus Martius. In the background behind the participants rises a monumental architectural facade described as a double temple or a distyle building with a colonnade, featuring prominent columns. In the field or exergue, the senatorial formula S C appears. This complex vignette illustrates the nocturnal or daytime sacrifices offered to the deities of the saeculum, such as the Moerae, the Ilithyiae, Terra Mater, or Jupiter and Apollo, grounding the numismatic image directly in the historical topography and sacred ceremonies of Rome.

Epigraphy and Imperial Titulature

The obverse legend reads: IMP CAES DOMIT AVG GERM P M TR P VIII CENS PER P P. This dense sequence of abbreviations translates to Imperator Caesar Domitianus Augustus Germanicus, Pontifex Maximus, Tribunicia Potestate VIII, Censor Perpetuus, Pater Patriae. The title Germanicus honors his military campaigns against the Chatti in AD 83, while Censor Perpetuus highlights his unprecedented assumption of the perpetual censorship in late AD 85, emphasizing his absolute supervision of Roman public morals and senatorial rolls. The inclusion of TR P VIII (holder of tribunician power for the eighth time) provides precise chronological grounding to AD 88. The reverse inscription reads: COS XIIII LVD SAEC FEC S C, which expands epigraphically to Consul Quartum Decimum, Ludos Saeculares Fecit, Senatus Consulto. This legend explicitly proclaims that Domitian, in his fourteenth consulship, celebrated the Secular Games under senatorial decree. The phrasing directly parallels the earlier commemorative coinage of Augustus from 17 BC, creating a deliberate historical and ideological connection between Domitian and the founder of the Principate. Letterforms are executed in clean, classical Roman capitals, spaced carefully around the perimeter and exergue to accommodate the densely packed figures.

Typology and Chronological Placement

The dating of RIC Domitian 621 is firmly established by the conjunction of Domitian's imperial titles. His eighth tribunician year ran from September 14, AD 88, to September 13, AD 89, while his fourteenth consulship commenced on January 1, AD 88, and continued through the year. The Secular Games were staged in the autumn of AD 88, precisely within the window where TR P VIII and COS XIIII overlapped. This pinpoints the production of this dupondius type securely to the late months of AD 88. Within the broader typology of the Secular Games series, the mint of Rome produced a coordinated multi-denomination programmatic suite in gold, silver, sestertii, dupondii, and asses. Each denomination illustrated distinct phases of the ceremonies, including the distribution of purifying suffimenta, the acceptance of fruges from the Roman populace, the various animal sacrifices, and the performance of sacred hymns by choruses of boys and girls. RIC 621 represents one of the primary dupondius varieties depicting the sacrifice at the altar before the river god and temple. Minor die variations occur in the rendering of the temple columns and the precise posture of the attendant figures, but the core compositional scheme remains consistent within this catalogued type.

Circulation and Archaeological Context

Although struck as part of a highly specific commemorative emission, the dupondii of the Secular Games were not presentation medallions; they were released directly into the mainstream currency pool of the Roman Empire. Middle bronze coins were essential components of low-to-medium value market transactions, circulating alongside asses and sestertii for purchasing foodstuffs, paying municipal dues, and facilitating retail trade. Archaeological and hoard evidence indicates that while the Ludi Saeculares bronzes originated at the central mint in Rome, they quickly dispersed throughout Italy and into the western military provinces along the Rhine and Danube frontiers, as well as Roman Britain. Because orichalcum dupondii were durable and valued above copper asses, they remained in circulation for decades. Many surviving examples of Flavian dupondii exhibit substantial surface wear, indicating that they continued to change hands well into the second century AD through the reigns of Trajan, Hadrian, and the Antonines, until monetary reforms and inflation gradually eroded the utility of earlier base-metal denominations.
