knot that gave its name to a proverbial term for a problem solvable only by bold action. In 333 BC, Alexander the Great, on his march through Anatolia, reached Gordium, the capital of Phrygia. There he was shown the chariot of the ancient founder of the city, Gordius, with its yoke lashed to the pole by means of an intricate knot with its end hidden. According to tradition, this knot was to be untied only by the future conqueror of Asia. In the popular account, probably invented as appropriate to an impetuous warrior, Alexander sliced through the knot with his sword, but, in earlier versions, he found the ends either by cutting into the knot or by drawing out the pole. The phrase "cutting the Gordian knot" has thus come to denote a bold solution to a complicated problem.
