The Secret History by Procopius

The deeds of Justinian were such that all eternity would not be long enough in which to describe them adequately. So a few examples will have to suffice to illuminate his whole character to future generations: what a dissembler he was, how he disregarded God, the priests, the laws, and the people who showed themselves loyal to him. He had no shame at all, either when he brought destruction on the State or at any misdeed; he did not bother to try to excuse his actions, and his only care was how he might get sole possession of all the wealth of the world. To begin:

As bishop of Alexandria he appointed a man by the name of Paul. At this time one Rhodon, a Phoenician, was Governor of that city. Him he ordered to serve Paul with all zeal, and to allow none of his instructions to be unfulfilled. For thus he thought he could associate all the priests in Alexandria under the synod of Chalcedon.
