\Gor"di*an\, a.
1. Pertaining to Gordius, king of Phrygia, or to a knot tied
   by him; hence, intricate; complicated; inextricable.
{Gordian knot}, an intricate knot tied by Gordius in the
   thong which connected the pole of the chariot with the
   yoke. An oracle having declared that he who should untie
   it should be master of Asia, Alexander the Great averted
   the ill omen of his inability to loosen it by cutting it
   with his sword. Hence, a Gordian knot is an inextricable
   difficulty; and to cut the Gordian knot is to remove a
   difficulty by bold and energetic measures.
