"The Sword of Damocles", an allusion to the imminent and ever-present peril faced by those in positions of power. The Damocles of the anecdote was an obsequious courtier in the court of Dionysius II of Syracuse, a 4th-century BC tyrant of Syracuse, Sicily.

According to the story, Damocles was pandering to Dionysius, his king, and exclaimed to him that Dionysius was truly fortunate as a great man of power and authority, surrounded by magnificence. In response, Dionysius offered to switch places with Damocles so that Damocles could taste that very fortune firsthand. Damocles quickly and eagerly accepted the king's proposal. Damocles sat down in the king's throne surrounded by every luxury, but Dionysius arranged that a huge sword should hang above the throne, held at the pommel only by a single hair of a horse's tail. Damocles finally begged the king that he be allowed to depart because he no longer wanted to be so fortunate, realizing that with great fortune and power comes also great danger.
