Antoninianus - Diocletianus IOVI AVGG, Jupiter

The IOVI AVGG legend — "to the two Augusti" — reflects the political architecture Diocletian had constructed by 286 AD when he elevated Maximian to co-emperor, binding the college of rulers to divine patronage with Jupiter assigned to Diocletian and Hercules to Maximian. This coin dates to the years immediately before the Tetrarchy was formalized in 293, when the two-man arrangement was already straining under the pressure of simultaneous frontier crises in Britain, Persia, and along the Rhine. RIC V.2 28 is attributed to the Antioch mint for this period, placing production far from Rome at a time when imperial administration had effectively decentralized.
