This web page wanders on and on with many interesting links and leads for further study. I found it a couple of weeks ago after thinking (and posting a little) about Whitsun/Pentecost and Rosemary Bergman who was the priest for the Christian Community in Chicago when I went there with my father in about 1972 or 73. In the search that came up with this page I was hoping there would be a picture of the painting over the alter at the Christian Community in Chicago currently. It's really three paintings making up one piece. A modern triptych. That truly glorious work isn't shown here, alas, but there are some photos of other questing art.
This particular article I will come back to again. It's a page-turner.
