I forget now in which book I originally came across a mention of the idea that the Celtic Cross was actually a device used thousands of years ago for land navigation and surveying purposes. When thinking about how people in ancient times set about traversing and exploring their landscape, whether of necessity or inquisitively, this idea that the cross with its circle in the centre enabling the rotation of four arms, stuck me as a profound idea and an incredibly sensible idea. Since then I came across the book by Crichton E M Miller, The Golden Thread of Time’ in which he sets out his claim to the idea. Summary snippets of it can be found written up, dotted around on the internet landscape. This, for me, is more than a nice idea, it’s one that appears to have a lot of credibility.
