Church windows

Directions: Enjoy, as always, the surprise of colored light streaming down upon the back stairway. Think of all times these windows were rewards for opening neglected doors and peering into forgotten rooms. Ask, with George Herbert:

Lord, how can man preach thy eternall word?
                  He is a brittle crazie glasse:
Yet in thy temple thou dost him afford
                  This glorious and transcendent place,
                  To be a window, through thy grace.
