I told you at what point the stone becomes invisible. 4 kms. Photos are utterly irrelevant, as what can be seen with the naked eye differs immensely from what a camera will pick up without using a zoom. (As with 4 winds photo. Not visible, but clearly visible with the naked eye from the same point.) Just because something similar has not been noticed before elsewhere, (if indeed that is true,) does not invalidate this case. The stone was erected, in a precise spot, which perfectly highlights the equinoxes from Carrigaruppera. Perhaps you would like to explain why you are so convinced this is coincidental, when on the balance of probability you are quite clearly wrong. I get the impression that this is more to do with proving intellectual superiority over others, than with an accurate assesment of what was really going on.
