Suetonius tells how the emperor Vespasian, who ruled between AD 69 and 79, was approached by a man who had invented a device for transporting columns to the Capitol, the citadel of Rome, at a relatively small cost. Columns were large, heavy, and very difficult to transport. Moving them to Rome from the mines where they were made involved the labor of thousands of people, at great expense to the government. Vespasian did not kill the man, but he also refused to use the innovation, declaring, “How will it be possible for me to feed the populace?”
