At one level, the labyrinth symbolizes the female womb, only penetrable if one is pure and perfect. The male figure outside, representing the human seed, can penetrate the womb, fertilize the ovum, produce new life, which then emerges as a new birth or a reincarnated existence. Entry into the labyrinth gives new life to litoi, thus achieving reincarnation and eternal life.
(Adrian Fisher & Georg Gerster)
