In het voetspoor van Athanasius Kircher
Documentary about seventeenth-century Athanasius Kircher (1601-1680), a visionary who studied nearly everything and interconnected everything to boot. He designed an eavesdropping device for the Pope, read magical records, but became particularly famous by deciphering the hieroglyphics. Apart from engravings from his books, the film shows two German spokesmen of the International Athanasius Kircher Scientific Society who travel to Rome in Kircher's footsteps. Verhoeff establishes that the journey leads to an underground world.
