This is the Rose Window at the Chartres Cathedral. Stained glass windows was the visible soul of the Middle Ages. This is a 13th century stained glass window and it caught my eye because I recently returned from a study abroad program in France, where we compared stained glass windows from multiple places. The amount of detail that goes into preparing a stained glass window is breathtaking, many even depict different stories from the Bible. I can see a lot of reds in this window, and the color red in stained glass windows was and still is the most costly of additives because it needs gold to be made. The windows at Chartres Cathedral is the most intact collection of medieval glass in the world, with measures of 26,900 feet in total area.
