The Summary of Physics Restored

26Because love stretches entirely beyond itself, divine nature, unable to endure solitude and admiring its own beauty in the light already created as in a mirror, burned to extend that light and multiply its own image. It commanded the light to spread and propagate. Then, as a fiery spirit proceeded from the divine mind and turned in a circle, the light began to act upon the neighbouring darkness. When this had been conquered and pressed down towards the centre, the second day shone forth and the second dwelling of light was established, or second heaven, embracing the entire ethereal region. In its upper part so many torches were afterwards scattered and fixed; in its lower part the seven wandering stars were placed in order, to give law to the nature beneath them through their light, motion and influence, like rulers and governors.
