Procopius, The Secret History of the Court of Justinian
“ He was a faithless friend, an inexorable foe, and mad for murder and plunder; quarrelsome and revolutionary, easily led to do evil, never persuaded to act rightly, he was quick to contrive and carry out what was evil, but loathed even to hear of good actions.How could any man fully describe Justinian's character? He had all these vices and other even greater ones, in larger proportion than any man; indeed, Nature seemed to have taken away all other men's vices and to have implanted them all in this man's breast. ”
