First things first, let’s sort out the difference between a maze and a labyrinth. “A maze usually has high walls to hide the route to the goal. It presents the walker with choices and dead ends — a puzzle to solve for fun,” says Andrew Wiggins, designer at The Labyrinth Builders (labyrinthbuilders.co.uk). “A labyrinth usually has a single meandering path with no choices to be made. The ‘walls’ are flat and it is walked as a contemplative experience.
“Put another way, ‘You enter a maze to lose yourself. You enter a labyrinth to find yourself’.”
Labyrinths also usually have only one entrance/exit, whereas a maze may have several. So, Theseus didn’t need a ball of string to get out of the Minotaur’s labyrinth.
