Plate taken from 'Ars Magna Lucis Et Umbrae' ('The Great Art of Light and Shadow') (published 1646) by the Jesuit priest and scholar Athanasius Kircher (1602-1680). In this book Kircher discused eclipses, comets and astrological influences, as well as colour, optics, sundials and magic lanterns. His major concern was with heavenly bodies believing, like Tycho Brahe (1546-1601), that the Sun and Moon circled the Earth, while the other five planets circled the Sun.
