Julia Domna RIC IV Caracalla 388A (antoninianus)

Monetary Context and the Antoninianus

The introduction of the antoninianus in early AD 215 represents one of the most critical structural transformations within the Roman imperial monetary system. Confronted by severe budgetary obligations, notably the substantial salary increase granted to the legions and extensive public expenditure, Emperor Caracalla sought an expedient solution to multiply the imperial treasury's purchasing power without requiring an equivalent influx of freshly mined bullion. The solution was the introduction of a new silver piece, conventionally designated the antoninianus by modern numismatists after the emperor's official name, Marcus Aurelius Antoninus. Contemporary literary sources do not preserve the original Latin name of the denomination, though some scholars conjecture it was simply termed a double denarius or argenteus. From a fiscal standpoint, the antoninianus was an overvalued fiduciary coin. While tariffed by imperial decree at two denarii, contemporary metallurgical analyses demonstrate that the average antoninianus weighed approximately 5.0 to 5.2 grams with a silver fineness hovering around fifty percent. In comparison, a contemporary Caracallan denarius averaged around 3.2 grams with a similar purity level. Consequently, an antoninianus contained only about one and a half denarii worth of physical silver, conferring a profit margin of roughly twenty-five percent upon the state with every specimen struck. To make the new denomination immediately recognizable to the public and avoid confusion in daily transactions, the mint adopted explicit denominational indicators. On male imperial portraits, the emperor wore a radiate sun crown recalling Sol, a convention previously utilized on double sestertii and dupondii. For the Augusta Julia Domna, the celestial counterpart of the radiate crown was deployed: a crescent moon situated beneath the truncation of her bust.

Production Standards and Mint Allocation

The entire attested emission of RIC IV Caracalla 388A (antoninianus) originates from the principal imperial mint at Rome. Unlike later third-century crises where provincial branch mints operated extensively in the East and Gaul, early antoninianus production remained tightly centered in the capital. The officinae at Rome were divided to execute concurrent emissions for Caracalla himself and for Julia Domna, who maintained a paramount administrative and ceremonial position in the Severan court as the Augusta and mother of the camps. Production of these coins followed strict blank preparation protocols, though the debased silver alloy, consisting of roughly equal parts silver and copper, required sophisticated surface enrichment. Blanks were pickled in mild acidic solutions prior to striking, leaching copper from the exterior layer and leaving a silver-rich crust that gave freshly minted coins a bright, lustrous appearance. Blank weights varied, but specimens of RIC IV 388A typically cluster in the range of 4.7 to 5.4 grams with diameters averaging between 22 and 24 millimeters. Dies were meticulously engraved by experienced artisans at the capital, displaying the high sculptural relief and refined portraiture characteristic of the late Severan Rome mint before the stylistic deterioration of the later third century.

Obverse Iconography of the Empress

The obverse of RIC IV Caracalla 388A features the mature, dignified portrait bust of Julia Domna facing right. In keeping with the high Severan court style, her hair is coiffed in an elaborate architectural arrangement, waved horizontally in tight, prominent ridges across the cranium before being drawn up low at the back of the neck in a broad, braided plait or chignon. She wears an imperial stephane or diadem crowning the coiffure, signaling her exalted status as senior Augusta. The defining denominational attribute of the bust is the lunar crescent upon which it rests. The upturned horns of the crescent curve below the drapery folds, symbolically linking the empress with Luna and Diana, celestial equivalents to the radiant solar imagery of Sol Invictus associated with the Augustus. The drapery is handled with plastic naturalism, falling over the shoulders in soft, layered folds. The obverse die execution portrays Julia Domna not as an idealized maiden, but as a seasoned dynastic matriarch, projecting authority, imperial continuity, and divine protection over the Severan regime.

Reverse Iconography of Venus Genetrix

The reverse of the coin type depicts Venus Genetrix, the ancestral mother and divine patroness of the Roman people and the imperial household. She is represented fully draped in classical stola and palla, seated facing left upon a throne. Her right hand is extended forward in an open, receptive gesture of benevolence and maternity, while her left hand supports a tall vertical sceptre, the conventional attribute of majesty and divine sovereignty. This iconography holds profound ideological resonance within the Severan monetary program. Venus Genetrix had been venerated since the late Republic and early Empire, especially by Julius Caesar, as the mythical progenitor of the Roman state. By selecting Venus Genetrix for Julia Domna's newly inaugurated double denarii, imperial propagandists emphasized the empress's maternal legitimacy, dynastic fertility, and vital role as the living anchor of the Severan succession. The throne and sceptre elevate the goddess to an enthroned cosmic ruler, echoing the empress's real authority within the imperial administration during Caracalla's frequent military absences.

Epigraphic Style and Legend Readings

The inscriptions on RIC IV Caracalla 388A are concise, formal, and unambiguous, rendered in clear imperial capitals along the peripheral rims of the dies. The obverse legend reads IVLIA PIA FELIX AVG, which expands to Julia Pia Felix Augusta. The epithets Pia and Felix, adopted by Julia Domna following the death of Septimius Severus in AD 211, mirror the standard imperial titles assumed by Caracalla, reinforcing her co-equal aura of piety and good fortune. The legend begins at the lower left perimeter, encircling the bust clockwise, neatly punctuated around the empress's head. The reverse inscription reads VENVS GENETRIX, describing the deity depicted on the field. The letters are balanced symmetrically around the enthroned goddess, typically starting low on the left and arching across the upper margin to the right. The lettering is cleanly cut with neat serifs typical of the urban mint at Rome. Epigraphic variations on this specific catalogue type are minimal, restricted primarily to spacing quirks or minor differences in letter height across individual die pairs, with no documented officina marks or mint signatures, as explicit mintmarks were not yet customary on Rome's silver coinage during this era.

Typological Placement and Chronology

The chronological envelope for RIC IV Caracalla 388A is tightly defined by institutional and numismatic evidence. While the cataloguing scope in Roman Imperial Coinage IV places Julia Domna's sole-reign Caracallan coinage within the broad parameters of AD 211 to 217, the specific denomination itself was not created until the monetary reform of early AD 215. Consequently, this antoninianus could only have been minted between AD 215 and the dual deaths of Caracalla and Julia Domna in the spring of AD 217. Within the antoninianus series for Julia Domna, RIC IV 388A constitutes one of a small, distinct suite of reverse designs. Other concurrent antoninianus issues for the Augusta featured Venus Victrix standing, Vesta veiled and holding the palladium, or Luna in a biga. RIC 388A is distinguished specifically by the combination of the seated Venus Genetrix reverse and the crescent-mounted draped bust with diadem on the obverse. While neighboring catalogue entries record variations in drapery, throne construction, or standing postures, RIC 388A specifically isolates the seated presentation holding a sceptre, establishing a stable typological benchmark for late Severan numismatic classification.

Circulation Patterns and Hoard Contexts

Upon its release into circulation, the antoninianus of Julia Domna functioned within an economy governed by Gresham's Law. Because the coin was overvalued by roughly twenty-five percent relative to its silver content against the traditional denarius, the public tended to spend the new antoniniani and hoard older, higher-purity Severan and Antonine denarii. Nevertheless, as the state paid military forces and civil servants predominantly in the newly minted double denominations, antoniniani spread quickly across the empire. Hoard evidence from Britain, the Rhine frontier, the Danube basin, and the Levant confirms that RIC IV Caracalla 388A circulated extensively alongside Caracalla's radiate antoniniani and surviving denarii. Although antoninianus production temporarily ceased under Macrinus and Elagabalus, who reverted primarily to the denarius standard, the coins issued under Caracalla remained in active circulation for decades. By the AD 240s and 250s, when Gordian III, Philip I, and Decius revived the antoninianus as the primary silver denomination, surviving Caracallan specimens of Julia Domna were frequently worn nearly flat from protracted commerce, before being driven out of circulation entirely by the hyper-debased billon antoniniani of Gallienus and Claudius II Gothicus.
