That is exactly what Mr T is doing! Saying this is unintentional and purely accidental. Curiously, in the 10 years since this was first spotted, he is the only person to have taken such a stance. The article on it was considered fit for publication by the Waterford Archaeological and Historical society, and they would not have done so had they had their doubts. I've been studying Coumaraglin for over 15 years, during which time Mike Power and I have discovered 4 other valid equinox and solstice alignments. When I start lecturing Mr T on rock art, he can start lecturing me on Coumaraglin. Believe me, on this occasion, he is way out of his depth.
