Thank you. There are free guided tours of the cathedral most days, and the people there are friendly and ready to talk about the wonder in which they work. Those magnificent mosaics are the work of a single pair of craftsmen, a father and a son. The father died before they could finish, and the son completed the work alone. I can't think of a better example of work as a prayer.
It's inspiring and yes, peaceful. If you're in St. Louis, check it out.
Mrs. Barbarian got the best shot, darn it.
