two sides of the same story.

the most easterly and largest stone in an array of 5 holed stones on truthwall common, tregeseal on the sloping ground below carn kenidjack. the projected shadows of which might function as markers for the approaching seasons. the holes are low down on the stones such that they would only appear in the projected shadow at low sun elevations ie at sunrise and sunset. in addition the holes have been fashioned in such a way that the ‘focus’ of the sun’s rays falls between the two surfaces of each stone; the holes tapering down from a larger diameter at the stone’s surface toward a smaller one at the stone’s centre and then out again forming a ‘lens’ so that the hole can be projected sharply onto the surface of the ground. is it possible that this might be used as a sun dial fixing the time of the solstices for example? as the position of the rising and setting sun moves with the changing seasons and the holes in each stone appear and disappear the approach of the seasons might be plotted?
