I grew up in both the Catholic and Orthodox churches with their highly ornate and pictorial windows, but I always liked this style of church windows as well, featuring the glass itself as well as the arrangement of the pieces. It’s especially fitting for a tiny chapel which would be overwhelmed by a figurative window. This simply let in colored light, and along with two other windows provided just this little bit of color in the dimness.
Often the patterns for these windows were entirely abstract, but just like looking at clouds, I always saw something in them. In this one I see a person praying. Now that’s not so outlandish.
