The years of plenty (left), with men pouring harvested grain from their clothes and the Egyptians storing provisions (right), with men pouring grain into storage boxes, from the Life of Joseph stained glass window, 13th century, in the nave of Chartres cathedral, Eure-et-Loir, France. Chartres cathedral was built 1194-1250 and is a fine example of Gothic architecture. Most of its windows date from 1205-40 although a few earlier 12th century examples are also intact. It was declared a UNESCO World Heritage Site in 1979. Picture by Manuel Cohen
