What is the Sword of Damocles?
assistant
The Sword of Damocles is a metaphor for the threat of imminent catastrophe or doom. It comes from the Greek legend of Damocles, who was a king who had a sword suspended above his head by a single horsehair. Damocles was so confident of his rule that he didn’t care about the sword, but he was afraid that it would fall on him at any moment and kill him.
