Many roots were sticking out of the dirt to provoke tripping, and Theseus used these to his advantage. As he moved his way around a corner, he noticed his string and knew he was in one of the architect’s roundabout traps.
As Daedalus had told him, the Minotaur would have his prey thinking they were running away, when they would eventually just be running in circles… perfect for capture.
Theseus used his string to his benefit here; as he knew the Minotaur eventually would, he waited until the bull-man was no longer following behind him. Theseus would then attack head-on.
Just as planned, the Minotaur emerged in front of Theseus and was surprised when the hero suddenly charged right back at him. Startled immensely, the Minotaur stumbled and fell to the ground with his foot catching on a root. Still charging at the beast, Theseus gave the him a swift kick to the back and killed him instantly.
