Just as in this corporeal world there is a light by means of which whatever things continue to be preserved, also in the archetype, that invisible and super celestial world, there is a light from which,as from an abundant source, all things proceed...and of which this material light is, so to speak, but a symbol.
Athanasius Kircher, Ars magna lucis et umbrae (1646) Roma

Athanasius Kircher(1602 – 1680) was a German Jesuit scholar and polymath who published around 40 major works, most notably in the fields of comparative religion, egyptology, geology, medicine and music.
