There is a story about a traveler from Italy who arrived at the French town of Chartres to see the great cathedral that was being built there. Arriving at the end of the day, he went to the site just as the laborers were leaving. He asked one man, covered with dust, what he did there. The man replied that he was a stonemason. He spent his days carving rocks. Another man, when asked, said he was a glassblower, who spent his days making slabs of colored glass for the windows. Still another workman replied that he was a blacksmith who hammered iron for a living.
