Brian Burgess, the sculptor, said,
It began when one woman who saw the statue fell to her knees and began praying. She was transfixed for more than thirty minutes and when she came out of the trance she said she had witnessed sparks coming from the eyes of the Christ figure. Now the word has spread and we have hoards of people coming along to pray and venerate the statue and many of them have said they have witnessed these sparks too.... I worked on the piece for about a year but I never saw any sparks apart from those coming from the welding torch.
Sparks or reflections? Or something else?
I'd recommend turning off the lights and checking for anything "anomalous" but then we know how it's so easy for us humans to hallucinate, specially when we're expectant and know what's supposed to be detected/perceive. The mere suggestion that we should alert people if we see sparks is enough to elicit the hallucination in some people.
Mesmerized by dancing suns and sparkling eyes. Human psychology is fascinating indeed.
