Gordium

According to ancient tradition, in 333 BCE Alexander the Great cut (or otherwise unfastened) the Gordian Knot: this intricate knot joined the yoke to the pole of a Phrygian wagon that stood on the acropolis of the city. The wagon was associated with Midas or Gordias (or both), and was connected with the dynasty's rise to power. A local prophecy had decreed that whoever could loose the knot was destined to become the ruler of Asia.
