The Secret History by Procopius

As soon as Justinian came into power he turned everything upside down. Whatever had before been forbidden by law he now introduced into the government, while he revoked all established customs: as if he had been given the robes of an Emperor on the condition he would turn everything topsy-turvy. Existing offices he abolished, and invented new ones for the management of public affairs. He did the same thing to the laws and to the regulations of the army; and his reason was not any improvement of justice or any advantage, but simply that everything might be new and named after himself. And whatever was beyond his power to abolish, he renamed after himself anyway.

Of the plundering of property or the murder of men, no weariness ever overtook him. As soon as he had looted all the houses of the wealthy, he looked around for others; meanwhile throwing away the spoils of his previous robberies in subsidies to barbarians or senseless building extravagances. And when he had ruined perhaps myriads in this mad looting, he immediately sat down to plan how he could do likewise to others in even greater number.
