An illustrative interpretation of Genesis 1:17, "And God set them in the firmament of the heaven to give light upon the earth,". The illustration should be reminiscent of spiritual and celestial themes often seen in medieval art, emphasizing the grandeur and magnificence of the biblical event. It's not a painting but created in a modern, digitized format. The firmament is depicted as a brilliant night sky full of glowing stars. Shining brightly among them are two major lights - presumably the Sun and Moon - casting their radiant glow upon the Earth. The style should capture the essence of traditional, pre-1912 art.
