. "The Gordian Knot is a legend of Phrygian Gordium associated with Alexander the Great. It is often used as a metaphor for an intractable problem (disentangling an \"impossible\" knot) solved easily by cheating or \"thinking outside the box\" (\"cutting the Gordian knot\"):\"Turn him to any cause of policy,The Gordian Knot of it he will unloose,Familiar as his garter\" (Shakespeare, Henry V, Act 1 Scene 1. 45\u201347)"@en . .
