Demonstration of the Long Megalithic Sightlines

My brother has just published another article on www.astro-archaeology.org which develops considerable evidence of very long sightlines to Sun and Moon on the horizon formed by Ireland seen from southern Wales. The focus for this system is a small dolmen called Llech y Drybedd (pron. Dribeth) shown left. 

This investigation indicates that the monument and its environs were used to very accurately establish astronomical sightlines so as to have developed the very advanced knowledge (contested) that are found in artifacts of the ancient knowledge such as the lunation triangle, aspects of Stonehenge, exact metrological portrayal of astronomical periods within the dimensions of monuments and so forth.

This work is important because it appears that the effectiveness of numerical artifacts will not be accepted by many until the means by which exact time periods were established by monumental complexes are shown. It appears that, far from the possible religious or ritual significance, these megalithic complexes were instruments for establishing exact astronomical knowledge.
