A Gordian knot (GOR-dee-un NAHT) is a problem apparently unsolvable due to its complexity and has its history in ancient Greece. A mythical peasant named Gordius became king of Gordium in Phrygia. He dedicated his wagon to his god and tied it to a beam with an intricate knot. Later, Alexander the Great discovered the knot as he was undertaking his campaign against Persia. Legend said that the man who could solve the Gordian knot would go on to conquer all of Asia. Alexander solved the problem his own way, by using his sword to cut through the knot. He then went on to conquer Asia.
