Jones suggests that the inspiration for many design elements of megalithic art may have began with induced hallucinations, interpreted by the Neolithic perspective of their otherworld beliefs (p. 160).
Poet Robert Graves explained, within his own belief system, that, "...the sacred kings of Bronze Age Ireland, who were solar kings of a most primitive type...were buried beneath these barrows; but their spirits went to 'Caer Sidi,' the Castle of Ariadne, namely Corona Borealis. Thus the pagan Irish could call New Grange 'Spiral-Castle' and, revolving a fore-finger in explanation, could say, 'Our king has gone to Spiral Castle': in other words, 'he is dead.'"
