To 'Cut the Gordian knot!'
Phrygians were without a king at one time. Next man to enter the city driving an ox cart should become their king - as predicted by an oracle!
Gordias a peasant farmer drove into town on an ox-cart. He was declared by the priests as their new king.
In gratitude, Midas his son dedicated the ox-cart to the God Zeus and tied it with an intricate knot.
When Alexander arrived, Phrygia had been reduced to a province of the Persian Empire.
Several themes of myth converged on the chariot
Midas was connected in legend with Alexander's native Macedonia, where the lowland 'Gardens of Midas" still bore his name.
The Phrygian tribes were rightly remembered as having once dwelt in Macedonia.
So, in 333 BC, while wintering at Gordium, Alexander the Great attempted to untie the knot. When he could not find the end to the knot to unbind it, he sliced it in half with a stroke of his sword, producing the required ends
This is the famous "Alexandrian solution"... Solving a difficult problem with one bold step.
That night there was a violent thunderstorm. Alexander's prophet took this as a sign that would grant Alexander many victories.
Once Alexander had sliced the knot with a sword-stroke, his biographers claimed in retrospect that an oracle further prophesied that the one to untie the knot would become the king of Asia.
