The dome ceiling symbolizes the roof of the world, and stained glass presents a huge map of the world. When light comes in through the stained glass, it illuminates the ocean and the five continents. Four colors are used to represent the four major elements of the world. Represents the earth, white for the wind, red for fire, and blue for water. Surrounding the five continents are the twelve constellations. The periphery of the pattern shows human activities and emotions on the earth in a semi-abstract form. What is to be expressed here is that humans are affected by astrology.
