Near the altar, the "columns" are organ pipes. If you have ever heard a pipe organ in a large cathedral, it is a sound like no other. The bass pipes almost seem to permeate the listener on a cellular level as music fills the space. When you hear such an organ played by a master, the very air becomes filled with life.
I am now dreaming about columns. I paint them by day and dream about them at night. On to arches. I wonder if they will start showing up in my dreams.
