Astronomy is truly the handmaid of science, and the road to knowledge. For if the heavens declare the glory of God, that science which opens a door to the investigation into the heavens, which declare God's glory, and furnishes the means of illustration of the firmament, where God's handiwork is seen and exhibited, is a Divine Science.
