Hadrian Bronze As, RIC II, Part 3 (second edition) Hadrian 815

Monetary Context and Denominational Function

In the monetary system established by Augustus and refined over the first two centuries of the Roman Empire, the as was the foundational base-metal unit of daily commerce. Struck predominantly in copper, or occasionally a related copper alloy, the as stood at one-fourth the value of the brass sestertius and one-sixteenth of the silver denarius. Two semisses or four quadrantes constituted an as, making it an accessible, small-value denomination vital for routine retail transactions, market purchases, and daily labor wages throughout Rome, Italy, and the European provinces. During Hadrian's principate (AD 117 to 138), the base-metal system maintained high standards of striking and uniform weight regulation, with the as typically calibrated around a target of approximately 10 to 12 grams. The issue catalogued as RIC II, Part 3 (second edition) Hadrian 815 participated directly in this everyday monetary circulation. It carried the letters S C on the reverse, signaling Senatus Consulto, which acknowledged the traditional senatorial authority over the striking of aes coinage in the capital, even while the emperor held executive command of the state finances and monetary policy.

Production Standards and Mint Attribution

This specific catalogue type was struck exclusively at the imperial mint in Rome. Under Hadrian, the mint of Rome operated in organized officinae capable of producing millions of bronze and brass planchets with remarkable stylistic consistency. The production of the bronze as required the preparation of cast planchets followed by hot or warm striking between hand-carved intaglio dies. Die-engravers at Rome exhibited a refined classicism during the mid-120s AD, rendering the emperor's features with high sculptural relief, realistic curling hair, and neatly incised drapery or neck truncations when applicable. In RIC 815, Hadrian is portrayed with a bare neck and laureate crown. Metallurgically, while catalogued generically as bronze or copper alloy within broad modern classifications, imperial Roman asses were traditionally prepared from unalloyed or lightly alloyed copper, distinguished from the bright orichalcum (brass) reserved for sestertii and dupondii. Die axes for this issue cluster heavily around the standard Roman medallic or inverted orientations (frequently 6 o'clock or 12 o'clock), reflective of disciplined workshop practices at the capital.

Obverse Iconography and Imperial Portraiture

The obverse of RIC II, Part 3 (second edition) Hadrian 815 displays the right-facing head of Hadrian wearing a laurel wreath. Hadrian's numismatic portraiture marked a profound aesthetic shift in imperial self-presentation through the introduction of a full, neatly trimmed beard, departing from the clean-shaven tradition maintained by previous emperors since Augustus (with the exception of mourning periods). The laurel wreath encircling the emperor's head serves as an enduring symbol of imperial victory, civic piety, and the protection of the Roman state. Engravers during the AD 125 to 127 period portrayed Hadrian with mature facial features, characterized by deeply set eyes, a prominent nose, and stylized locks of hair that reflect contemporary Hellenistic and classical Roman sculpture. The truncation of the neck is cleanly rendered without bust drapery or cuirass in this primary variety, focusing attention squarely on the sovereign's likeness and serene imperial authority.

Reverse Design: Minerva Advancing

The reverse iconography features Minerva, one of the central deities of the Capitoline Triad, advancing briskly toward the right. She is depicted wearing a belted chiton or stola, occasionally with her aegis, and her head is crowned with a crested Corinthian or Attic helmet. In her upraised right hand, she brandishes a spear poised for thrusting, while on her left arm she carries a circular shield (clipeus) held defensively before her body. The dynamic posture of Minerva, caught in mid-stride, conveys active vigilance, defensive strength, and divine guardianship over the empire. Minerva held an esteemed place in Hadrian's ideological programs, embodying both military valor (virtus) and wisdom, statecraft, and the patronage of the arts (sapientia). By employing the combative Minerva motif on everyday bronze denominations, the imperial administration underscored that the peace and cultural flourishing of the Hadrianic golden age were secured by vigilant military preparedness.

Epigraphy and Inscriptional Analysis

The inscriptions on RIC II, Part 3 (second edition) Hadrian 815 illustrate the streamlined epigraphic style introduced during Hadrian's middle reign. The obverse legend reads HADRIANVS AVGVSTVS, positioned continuously along the rim. This concise formula abandoned the lengthy familial and adoptive designations seen on earlier issues, such as IMP CAESAR TRAIANVS HADRIANVS AVG P M TR P COS III, which had dominated the coinage from AD 119 to approximately AD 124. The reverse legend is similarly restrained, reading simply COS III across the upper or outer perimeter, signifying Hadrian's third consulship, which he entered in AD 119 and held for the remainder of his life without renewing the office. Across the lower fields of the reverse, flanking Minerva's figure, are the prominent capital letters S and C. These letters abbreviate Senatus Consulto ('by decree of the Senate'), affirming the traditional legal fiction and administrative division that base-metal coinage was sanctioned through senatorial authority.

Typological Classification and Chronological Framework

In the original 1926 second volume of Roman Imperial Coinage edited by Mattingly and Sydenham, Hadrian's aes coinage was organized along broad thematic lines, creating chronological ambiguities regarding issues bearing COS III. In the definitive 2019 revision, RIC II, Part 3 (second edition) by Richard Abdy and Peter Harling, the typology was thoroughly restructured into precise chronological groups based on obverse legend progression, portrait styles, and hoard analyses. Type 815 is firmly located within Group 3 of Hadrian's Rome mint issues, struck between AD 125 and 127. It is classified alongside parallel denominations, including the sestertius and dupondius, which share the simplified HADRIANVS AVGVSTVS legend. While the radiate crown distinguished the dupondius from the laureate as, the Minerva advancing type was struck across multiple denominations, with RIC 815 designating specifically the laureate bronze as with Minerva advancing right holding spear and shield.

Distribution, Hoarding, and Everyday Circulation

As low-denomination fractional currency, the asses of Hadrian circulated extensively across the western and central provinces of the Roman Empire, including Roman Britain, Gaul, the Rhine and Danube frontiers, and the Italian peninsula. Unlike gold aurei and silver denarii, which frequently traveled over long distances or were buried in wealth-preserving savings hoards, copper asses were subject to constant everyday handling, resulting in heavy abrasive wear, corrosion in soil, and frequent loss in urban and military settlements. Excavations at military fortresses along Hadrian's Wall and limes outposts in Upper and Lower Germany demonstrate that base-metal issues from the mid-120s AD remained in active circulation for decades, often circulating into the Severan era alongside earlier Flavian and Trajanic issues. Over time, circulation wear often softened the sharp details of Minerva's spear and the peripheral inscriptions, but the distinctive advancing silhouette and Hadrian's laureate portrait ensured ready recognition among soldiers and civilians alike.
