The Secret History by Procopius

Now this went on not only in Constantinople, but in every city: for like any other disease, the evil, starting there, spread throughout the entire Roman Empire. But the Emperor was undisturbed by the trouble, even when it went on continually under his own eyes at the hippodrome. For he was very complacent and resembled most the silly ass, which follows, only shaking its ears, when one drags it by the bridle. As such Justinian acted, and threw everything into confusion.

As soon as he took over the rule from his uncle, his first measure was to spend the public money without restraint, now that he had control of it. He gave much of it to the Huns who, from time to time, entered the state; and in consequence the Roman provinces were subject to constant incursions, for these barbarians, having once tasted Roman wealth, never forgot the road that led to it. And he threw much money into the sea in the form of moles, as if to master the eternal roaring of the breakers. For he jealously hurled stone breakwaters far out from the mainland against the onset of the sea, as if by the power of wealth he could outmatch the might of ocean.
