Explanation: The Roman Emperor Diocletian was a brutal tyrant who wrecked the government structure of the Empire, and then fucked off to a nice villa in Croatia to garden, becoming the only Emperor to (mostly) voluntarily peacefully retire instead of dying in office.

When one of his co-rulers begged him in a letter to return and help unfuck the mess he made, Diocletian wrote back saying that his co-ruler would not ask such a thing of him if he could see the satisfying and serene cabbages he grew with his own hands.

... points for the peaceful retirement, at least.
