Marcus Aurelius Denarius, RIC III Marcus Aurelius 185

Monetary and Historical Context

During the mid-second century AD, the Roman denarius formed the backbone of everyday urban trade and interprovincial commerce across the Mediterranean and European provinces. Struck in silver, it also served as the primary vehicle for state expenditures, especially military pay, administrative salaries, and imperial largesse. Under Antoninus Pius (AD 138-161), the denarius maintained an enviable physical consistency, but the ascension of Marcus Aurelius and Lucius Verus in AD 161 initiated immediate fiscal pressures. A major eastern conflict, the Roman-Parthian War of AD 161-166, compelled the treasury to mobilize substantial metallic reserves to fund legionary mobilizations, logistics, and donatives. Upon the victorious conclusion of the eastern campaign, the empire faced an immediate and devastating catastrophe: the Antonine Plague, brought back by troops returning from Mesopotamia. Compounding the epidemiological crisis, Germanic and Sarmatian tribes crossed the Danube border, threatening the northern provinces and northeastern Italy. By early AD 168, both Augusti determined that imperial presence was required at the front. The issue of RIC III Marcus Aurelius 185 coincided directly with this mobilization. The silver coinage struck in Rome in this year performed the vital function of funding the expeditionary forces while projecting ideological confidence to the civilian population and the senatorial elite, reminding users of past eastern victories and framing the northern journey as an enterprise under divine protection.

Production Standards and Mint Organization

The sole administrative mint responsible for striking RIC III Marcus Aurelius 185 was the central imperial mint at Rome. Unlike provincial silver issues, such as the cistophori of Asia Minor or the tetradrachms of Roman Syria, imperial denarii were centralized at the capital to ensure uniform administrative oversight, stylistic consistency, and strict metallic alloy control. The Rome mint operated through distinct officinae or workshops, each handling specific reverse types or portions of the imperial family's coinage under the direction of the equestrian procurator monetae. In terms of physical metrics, denarii of this issue adhere to the contemporary standards established under Marcus Aurelius. Following the Neronian reform of AD 64, the denarius had been reduced to a theoretical weight of 1/96th of a Roman pound (approximately 3.38 grams). By AD 168, the median striking weight tended to fluctuate between 2.90 and 3.40 grams, with typical diameters ranging between 17 and 19 millimeters. Metallurgical analyses of Antonine silver, notably conducted by Butcher and Ponting, demonstrate that the intrinsic silver fineness of the denarius under Marcus Aurelius stood at roughly 75 to 79 percent, with copper forming the bulk of the alloy. The blanks were cast in globular moulds and struck between hand-engraved bronze or iron dies, often displaying slight axis variations, although six o'clock or twelve o'clock alignments were common.

Obverse Iconography and Imperial Image

The obverse of RIC III Marcus Aurelius 185 features the right-facing, laureate head of Marcus Aurelius. The portraiture belongs to the emperor's mature iconographic phase, often classified by art historians as his third or fourth official portrait type. Marcus is depicted with deeply carved, voluminous hair arranged in thick, spiraling curls across the brow and crown, a style influenced by Antonine court aesthetics and the classicizing tastes of the Second Sophistic. His full, textured beard is carefully modeled, conveying both mature gravitas and the intellectual persona of a committed Stoic philosopher-prince. The laurel wreath encircling his head is tied at the nape of the neck with two ribbon ends falling down toward the drapery line or bare neck truncation. Unlike contemporary bronze medallions or select special gold issues where full military cuirasses or paludamenta are prevalent, standard silver denarii of this type typically present the head bare-necked, focusing visual attention strictly on the emperor's physiognomy and the triumphant laurel wreath. The die engraving at Rome during this period achieved exceptional sculptural relief, conveying dignified composure despite the immense geopolitical pressures bearing upon the imperial administration.

Reverse Iconography: Fortuna Redux

The reverse iconography of RIC III Marcus Aurelius 185 presents Fortuna Redux, seated left on a low-backed seat or stool. She is draped in a long stola with an outer mantle that gathers around her waist and falls gracefully over her legs. In her right hand, Fortuna holds a rudder that rests vertically upon the ground line beside her seat, symbolizing her role as the helmsman who steers human destiny and safely guides voyages through treacherous waters. In her left arm, cradled close to her body, she holds a cornucopiae overflowing with fruits and grain, representing the abundance, prosperity, and peace that imperial guidance guarantees to the Roman realm. The cult of Fortuna Redux had deep Augustan roots, linked historically to the safe return of Augustus from the East in 19 BC and commemorated by the Senate's dedication of an altar near the Porta Capena. In Roman imperial numismatics, the appearance of Fortuna Redux was rarely generic; rather, it signaled a specific, monumental imperial departure or anticipated homecoming. In AD 168, the figure on the reverse directly addressed the journey of Marcus Aurelius and Lucius Verus to the northern front in Pannonia. By portraying Fortuna seated and holding the rudder, the coin communicated that the helm of state was stable, and that the gods would oversee the emperors' perilous journey and ensure their victorious, safe return to Rome.

Inscriptions and Epigraphy

The inscriptions on RIC III Marcus Aurelius 185 provide an exacting epigraphic record of the coin's political messaging and constitutional dating. The obverse legend reads M ANTONINVS AVG ARM PARTH MAX. This expands to Marcus Antoninus Augustus, Armeniacus, Parthicus Maximus. Marcus dropped his birth nomen (Annius) upon adoption into the Aurelian line and ruled as Marcus Aurelius Antoninus. The cognomina ex virtute 'Armeniacus' (conqueror of Armenia) and 'Parthicus Maximus' (greatest conqueror of Parthia) had been accepted by Marcus in AD 164 and AD 166 respectively, following the campaigns managed by Lucius Verus and their generals in the East. Their inclusion on a denarius struck in AD 168 served to bolster military legitimacy prior to embarking on the hazardous northern campaigns. The reverse legend is inscribed FORT RED TR P XXII IMP V COS III, which divides into two distinct thematic elements. The initial phrase, FORT RED, is an abbreviation for Fortunae Reduci ('To Fortuna who brings back'). The remainder provides the emperor's constitutional titulature: Tribunicia Potestate XXII (holding tribunician power for the twenty-second time), Imperator V (acclaimed imperator for the fifth time), and Consul III (consul for the third time). Because Marcus Aurelius celebrated his twenty-second tribunician renewal beginning in December AD 167 and concluded it in December AD 168, and took his fifth imperial acclamation during this interval, the legend decisively fixes the minting of this denarius to the calendar year AD 168.

Typology and Chronological Classification

In the standard typological framework of The Roman Imperial Coinage (RIC), volume III, compiled by Harold Mattingly and Edward A. Sydenham, this coin is designated as entry 185 under the reign of Marcus Aurelius. In Wolfgang Szaivert's specialized classification of Antonine coinage, Die Münzprägung des Kaisers Marcus Aurelius (MIR 18), the issue is categorized under the 16th emission of the Rome mint for the year AD 168. Szaivert's structural analysis of die linkages and emission sequences confirmed that the Rome mint struck this issue concurrently with companion issues honoring Lucius Verus, who held parallel titles (TR P VIII IMP V COS III). Numismatists differentiate RIC III 185 from close variants and neighboring catalog entries through its specific combination of obverse titles, reverse bust treatment, and reverse legend breaks. While some contemporary denarii feature Marcus Aurelius standing or sacrificing, or introduce the personifications of Aequitas, Pax, or Providentia, RIC 185 is restricted strictly to the seated Fortuna Redux type with TR P XXII. Earlier Fortuna Redux types had been struck under Marcus in previous years, notably during the eastern war, but those carry earlier tribunician numbers (such as TR P XIX or TR P XX). RIC 185 therefore occupies a narrow chronological window in mid-AD 168, struck precisely as the joint emperors mobilized and departed for Aquileia.

Circulation, Hoards, and Archaeological Evidence

Following its release from the Rome mint in AD 168, RIC III Marcus Aurelius 185 circulated extensively throughout the Roman world. Because military expenditures on the Danubian limes absorbed vast quantities of silver coin during the late 160s and 170s, significant numbers of these denarii were carried north by legionaries and auxiliary units stationed in Raetia, Noricum, Pannonia, and Moesia. Hoard evidence from central Europe and Britain confirms that Antonine denarii formed the primary bulk of silver currency in circulation during the late second and early third centuries AD. Notable hoards, such as the Shapwick hoard in Somerset, England, and numerous continental deposits across the Rhine-Danube frontier, regularly contain specimens of Marcus Aurelius's middle-period coinage. The relatively high silver purity of the mid-Antonine issues meant that they remained favored commercial currency long after their striking. Many specimens continued to circulate well into the Severan era, suffering substantial wear until the severe debasements of the mid-third century caused older, purer denarii of Marcus Aurelius to be systematically culled, melted down, or hoarded in private caches.
