“The laser beam hits the black crust formed on the surface of the statues over the years, and that absorbs energy and disintegrates,” said Vassiliadis, who heads the six-strong team. “The crust has a much lower resistance threshold than the marble, which is not affected.” (AP Photo/Thanassis Stavrakis)
