This weekend, I was in Chicago with my family, having a Passover seder at their synagogue, when I noticed the most gorgeous stained glass windows. These windows depict bible stories, and are designed by an artist called William Gropper. Although his other art work is not my cup of Manishewitz, these windows left me transfixed. Instead of traditional stained glass techniques, Gropper used one inch thick chunks of brilliantly colored glass which were cut to shape and chipped or faceted on the surface. Each window is two stories high and contain 11 panels this chiseled glass set in a matrix.
