The Gordian Knot ... Myth and Legend
In the ancient town of Phyrgia, Greece, there lived a king called Gordius. He claimed that an Oracle came to him in the middle of the night and instructed him to tie a very complicated knot around the coupling of his wagon and that he whosoever would untie this knot would become ruler of all of Asia. Men came from near and far and none could do this. Then along came Alexander the Great, and try as he might, could not undo the knot. In anger and frustration, he raised his sword and slashed the knot. He did indeed became the ruler of all of Asia!
