Domitian Sestertius, RIC II, Part 1 (second edition) Domitian 78A

Monetary Context and Imperial Accession

The sestertius of early Flavian Rome stood as the principal large-module brass denomination of the imperial currency system, valued at four asses or one quarter of a silver denarius. When Titus died on September 13, AD 81, Domitian rapidly assumed imperial authority, requiring the mint of Rome to replace the coinage of the deceased princeps with emissions inaugurating the new administration. As the largest and most visually commanding denomination struck in orichalcum or bronze, the sestertius served as a paramount medium of official civic messaging. Type 78A was struck within this immediate transitional context, articulating the continuity of the Flavian dynasty while establishing the individual ideological identity of the new emperor.

Production Standards and the Rome Mint

Production of RIC II, Part 1 (second edition) Domitian 78A occurred exclusively at the central imperial mint in Rome. First-century imperial sestertii were typically struck on thick cast flans composed of orichalcum (copper alloyed with zinc) or related leaded copper alloys, averaging approximately 24 to 28 grams in mass and roughly 33 to 35 millimeters in diameter. Dies were hand-engraved with substantial relief to accommodate high-pressure manual striking. Die alignment in this period generally adhered to a regular vertical axis (six o'clock or twelve o'clock). The striking of base-metal denominations remained formally supervised under senatorial tradition, indicated by the prominent formula S C on the reverse field.

Obverse Iconography and Styling

The obverse die features a mature, dignified right-facing bust of Domitian. The emperor is depicted wearing the laurel wreath of victory and authority, with drapery gathered distinctly on his left shoulder. Flavian portraiture on early bronze issues of Domitian exhibits a stylistic continuation of the muscular, realistic modeling characteristic of Vespasian and Titus, while gradually introducing the distinct facial structure, prominent forehead, and receding hair associated with Domitian. The peripheral legend encloses the portrait field with precise, upright imperial lettering.

Reverse Design and the Cult of Minerva

The reverse iconography introduces the goddess Minerva, standing facing left and holding a vertical spear in her right hand, while her left hand rests along her side. Minerva was selected as Domitian's foremost personal protectress, and her imagery would dominate his coinage throughout his fifteen-year reign across various compositional formats. On this early accession sestertius, the goddess appears in a stately, classical posture rather than the more aggressive, brandishing martial poses that proliferated in later emissions. Flanking the lower fields of the goddess, the senatorial letters S and C reinforce the traditional partnership between princeps and Senate in the issue of bronze currency.

Epigraphic Formulations and Titulature

The obverse inscription reads IMP CAES DIVI VESP F DOMITIAN AVG P M, transcribing as Imperator Caesar, Divi Vespasiani Filius, Domitianus Augustus, Pontifex Maximus. This formula explicitly promotes Domitian as the son of the deified Vespasian, anchoring his dynastic credentials, and confirms his swift assumption of the high priesthood (Pontifex Maximus). The reverse inscription, TR P COS VII DES VIII P P S C, documents his tribunician power (Tribunicia Potestate), seventh consulship, designation for an eighth consulship (Consul VII, Designatus VIII), and the title Pater Patriae (Father of the Fatherland), followed by Senatus Consulto. These precise magistracies confirm that the coin was prepared before January 1, AD 82, when Domitian formally entered his eighth consulship.

Typological Classification and Chronological Placement

In the standard classification established by Harold Mattingly and thoroughly revised by Ian Carradice and Theodore V. Buttrey, type 78A is isolated as a distinct variant within the first issue of Domitian's bronze coinage of AD 81. It differs from neighboring entries in specific drapery placement on the obverse bust and the exact stance and attributes of Minerva. Because the legend designates Domitian as consul for the seventh time and designated for an eighth term, numismatists securely place the manufacture of this issue in late autumn or early winter of AD 81, between his accession in September and the close of the calendar year.

Circulation Patterns and Archaeological Evidence

Flavian sestertii circulated broadly across the western provinces of the Roman Empire, including Italia, Gaul, Hispania, and the Rhine-Danube military frontiers. Due to their substantial intrinsic and nominal value, sestertii remained active in commercial circulation for decades, often exhibiting heavy wear in second-century hoard deposits. While later Domitianic bronze is noted for rigorous monetary control and increased metallic purity following the monetary reform of AD 82, the early AD 81 issues like type 78A were minted in relatively limited quantities compared to the expansive production cycles of subsequent years.
