Under the circumstances, who wouldn’t want to retire? By 305 AD, Diocletian had served for two decades as Rome’s Augustus, enacting massive military, economic, and political reforms. He was over 60 years old — well beyond the average life expectancy of the era — and gravely ill. The venerated Augustus was ready for a change of pace. He had already commissioned the construction of his massive retirement fortress, known today as Diocletian’s Palace, along the beautiful Dalmatian coast (modern Split, Croatia).
Diocletian’s reign was remarkable for its total reorganization of Roman society. Yet, his boldest move was his exit. Satisfied with his achievements and conscious of his frailty, Diocletian planned his own abdication. In typical punctilious fashion, he also compelled his co-Augustus, Maximian, to do the same. This intentional transfer of the purple to their respective Caesars (Galerius and Constantius) was unprecedented in the history of the Empire. Emperors usually left the throne in a coffin, not a carriage.
The abdication took place on May 1, 305 AD, on a spacious plain outside Nicomedia. Addressing the legions, the Emperor formally stepped down, citing his infirmity and his desire to turn the Empire over to younger, stronger hands. After divesting himself of the purple robe, Diocletian departed via covered chariot to Dalmatia. Meanwhile, in Milan, a reluctant Maximian abdicated in a similar ceremony.
This bronze nummus, struck at the Serdica mint (c. 305-306 AD), is a fascinating piece of political propaganda designed to normalize this transition. The obverse features a dignified, laureate bust of the former Emperor holding an olive branch and a mappa (a ceremonial cloth). The legend grants him a new, unique title: D N DIOCLETIANO BEATISSIMO SEN AVG (Our Lord Diocletian, Most Happy/Blessed Senior Augustus).
The reverse is even more telling. It depicts Providentia (Foresight) extending a hand to Quies (Quiet/Rest). Quies is an extremely rare figure in Roman numismatics; she is the divine personification of tranquility. The legend PROVIDENTIA DEORVM QVIES AVGG (" The Foresight of the Gods, the Rest of the Augusti") frames the abdication not as a resignation, but as the fulfillment of a divine plan. It tells the public: "The Emperors are not quitting; they have earned their rest."
Until his death (c. 311 AD), Diocletian enjoyed this "Blessed and Happy" retirement. He largely stayed out of politics, though he was briefly roused to attend a conference at Carnuntum in 308 AD to mediate a dispute between his squabbling successors. When invited to return to power permanently, the old man famously refused, preferring his garden to the throne. His reply to the ambassadors remains one of the great quotes of antiquity:
If you could show the cabbage I planted with my own hands to your emperor, he definitely wouldn't dare suggest I replace the peace and happiness of this place with the storms of a never-satisfied greed.
