because they both had a tied knot and had a huge reward for untieing it
The Gordian Knot of history was a complicated Turk's Head, tied with the bark of the Cornel Tree. Over time, the bark shrank and hardened, making it impossible to untie. Many tried, and ALL failed....
It was said to be impossible to be untied -and so it was cut asunder by sword, using 'the Alexandrian solution' -a bold stroke!
It was cut loose by Alexander (the Great) with a bold stroke of his sword, hence the term: the Alexandrian solution.
There are no evidence of that.
A man named Gordius secured his donkey with it.
