Dioclétien

A Dalmatian soldier proclaimed in 284, Diocletian ended fifty years of chaos by reinventing the empire: power shared among four, the tetrarchy; the provinces redrawn; taxation recast; the currency remade with a new coin, the nummus. After twenty-one years he did what no emperor had done: he abdicated, in 305, and ended his days at Split, growing his cabbages as the famous remark has it.

This coin dates from the beginnings: Maximian associated in the West, the frontiers closing one by one, and a currency still inherited from Aurelian.
