The mysteries of the rosary placed on the chapel walls want to remind us of rosary beads. “The light, glass melted into one, opalescent, and blown, want to express the poetry as well as the force and the excitement of the facts told in the twenty mysteries. Four fragments of a large crown hung on the wall, are crossed by a strip of the golden mosaic that expands sideways. The colours of the Joyful Mysteries are fresh and transparent. Those of the Luminous Mysteries are full of light and joy… they become dark and dramatic in the Sorrowful Mysteries but then return to being warm and lively in the Glorious Mysteries.
