Diocletian

"The reason generally assigned for this absence of early records is that Diocletian burned all writings of the Egyptians bearing upon alchemy, because, as he said, these taught the art of making gold and silver; and, by destroying them, he took away... the power of enriching themselves and rebelling against the Romans."

"The reforms of Diocletian were a work of genius and made many people temporarily happy, but failed in the end and added greatly to human misery. I see no reason why this inferior modern copy of them should succeed."

"In 302, the Roman emperor Diocletian commanded "there should be cheapness," declaring, "Unprincipled greed appears wherever our armies … march. … Our law shall fix a measure and a limit to this greed." The predictable result of Diocletian's food price controls were black markets, hunger and food confiscation by his soldiers. Despite the disastrous history of price controls, politicians never manage to resist tampering with prices -- that's not a flattering observation of their learning abilities."
