Archeologist Alberto Scuderi, geoarcheologist Francesca Mercadante and her husband and co-explorer Dr. Pippo Lo Cascio have discovered that a seven-foot high rock with a hole carved out of it on a hilltop in Palermo province was actually a second-millenium B.C. megalithic structure that celebrates the winter solstice. On December 22 the first rays of the sun pass through its hole, visible for kilometers all around, announcing the end of winter and the comforting return of the sun and longer days.
