These are apparently special magical lines that run between ancient archaeological sites or monuments. If like me, you grew up devouring all the mystical books doing the rounds such as “Chariot of the Gods” by Erich Von Daniken, or “The Third Eye” by Lobsang T Rampa, then you will have no doubt come across the claim at some point. In fact, I’d be astonished if you had not heard of them, the idea has more or less embedded itself as a cultural meme these days.
