Healing
Two large figures in the center of the window evoke the work of mercy captured in the phrase
"I was sick and you visited me."
One represents a sick man with a skull, a reminder that the physician (the second figure) attends to us from birth to death and is the guardian of our physical life. Things to look for: a microscope, test tubes, and other lab equipment; the caduceus (a staff with two intertwined serpents).
