A twelve labours denarius of Postumus


Last year I managed to acquire an example of a coin that had been on my “bucket list” for many years. The coin in question is variously described as a denarius or as an abschlag, an off metal strike from dies intended for gold coinage, in this case an aureus die.

POSTVMVS PIVS FELIX AVG
Laureate, cuirassed bust of Postumus with bust of Hercules, jugate, right
HERCVLI NEMAEO
Hercules facing left wrestling Nemean lion
Mint 1 (Trier), Schulte group 11a
Schulte 122, RIC 349, Elmer 523

Schulte records a number of aurei and denarii of Postumus with the bust jugate with Hercules on the obverse. However, the coins of Schulte’s 11th group are of particular interest. In this group there are a series of reverse types that depict some of the twelve labours of Hercules.

Schulte’s 11th group is dated to AD268 and is associated with the fourth consulate of Postumus and the beginning of his decennalia celebrations, but why the association with the labours? It has been suggested that this special group of coins marks the conclusion of a struggle and it may be no coincidence that Postumus inflicted a defeat on Gallienus at this time. In this defeat we learn from the ancient writer Zonaras that Gallienus was significantly wounded, being struck by an arrow in the back.

To support this theory there is, in Schulte’s 11th group, a denarius that combines the Postumus and Hercules jugate bust with the PAX AVG reverse from antoninianus dies, suggesting a period of tranquility was occurring.

Furthermore, in the antoninianus coinage, besides the usual right facing, radiate, draped and cuirassed bust of the emperor on the obverse Postumus also uses a special, rare, left facing die. A radiate, draped and cuirassed but of the emperor is augmented with the club of Hercules over the emperor’s right shoulder and the skin of the Nemean lion adorning the left, again hinting that the trials are over.

The Herculian labours coins are all of the greatest rarity. The superb Thys collection of Gallic coins was lucky enough to have four of the labours denarii, but not the Nemean lion type. In Schulte type 122 is represented by only a single example (British museum, ex de Salis, Sparkes and Dupree collections), making this piece probably only the second recorded example.
