Curtains open to reveal a female figure holding a lyre labelled 'harmonia' in her right hand and a triangle labelled 'symetria' in her left. Her head is the sun and around it are the other six planets. Within her body we see a growing child, her digestive system is shown with grains and vines. Her intestines have the symbols of the planetary metals antimony and sulphur added. A hand from the left gestures 'ratio', while another from the right bears 'experientia'.]
