Aureus - Maximianus IOVI CONSERVAT AVGG, Jupiter

This aureus falls within the Diocletianic reform period, before the currency overhaul of 294 AD that restructured the entire Roman monetary system. Maximianus, appointed co-emperor by Diocletian in 285, issued coinage invoking Jupiter as divine protector of both emperors — the AVGG plural genitive makes explicit that the protection extends to the imperial college, not a single ruler. The theology was deliberate policy: Diocletian took Jovius, Maximianus took Herculius, anchoring the Tetrarchic ideology in divine patronage before the full four-man system was formalized.

RIC V.2 492E places this among the earlier Lugdunum or Ticinum issues. Gold from this transitional window is substantially rarer than the post-294 reformed coinage.
