Sphinx

The next generation of politicians, all as mediocre as one another, and competing with one another for primacy with little concern for the good of the state, abdicated the control of affairs to the whims of the people. They concentrated on their personal intrigues and ambitions instead of exercising any sort of leadership; they undermined any influence they might have had overseas, and plunged their own societies into factional conflict.

(Thucydides 2.65, very loosely adapted)
