Gordian Knot
The cutting of the Gordian Knot is an Ancient Greek legend associated with Alexander the Great in Gordium in Phrygia, regarding a complex knot that tied an oxcart. Reputedly, whoever could untie it would be destined to rule all of Asia. In 333 BC, Alexander was challenged to untie the knot. Instead of untangling it laboriously as expected, he dramatically cut through it with his sword. This is used as a metaphor for using brute force to solve a seemingly-intractable problem.

BISHOP OF CANTERBURY
Hear him but reason in divinity
And, all-admiring, with an inward wish
You would desire the King were made a prelate;
Hear him debate of commonwealth affairs,
You would say it hath been all in all his study;
List his discourse of war, and you shall hear
A fearful battle rendered you in music;
Turn him to any cause of policy,
The Gordian knot of it he will unloose
Familiar as his garter; that, when he speaks,
Hear him but reason in divinity
And, all-admiring, with an inward wish
You would desire the King were made a prelate;
Hear him debate of commonwealth affairs,
You would say it hath been all in all his study;
List his discourse of war, and you shall hear
A fearful battle rendered you in music;
Turn him to any cause of policy,
The Gordian knot of it he will unloose
Familiar as his garter; that, when he speaks,
