Before I go any further, I need to talk about archaeoastronomy and the issue of accuracy. Modern science has allowed us to become accurate within millimicrons, no, down to minute bits of atoms. I do not believe it is necessary in the construction of sacred spaces to be that accurate. I've even left out certain calculations like how much the Sun's rays are bent as it comes over the horizon. Sig looking down the major axis of the labyrinth towards the mouth.
Sacred space is created through intent.
Elizabeth Sulivan intended tomake a place of healing, she dowsed the orientation of her labyrinth. This would be from the goal, through the mouth, to the horizon. A bit over one degree off. My calculations, as accurate as I attempted to be, could easily be that much off. Elizabeth also dowsed the necessity of these circles and each stone's location.
