This marvelous engraving is a miniature version of Athanasius Kircher's early view of the sun, first published in 1665 in his Mundus Subterraneus (The Underground World). The engraving graphically depicts the sun's solar flares and surface eruptions based on the observations of Kircher and Christoph Scheiner in 1635. Happel published this miniature edition in Mundus Mirabilis Tripartitus oder Wunderbare Welt in einer Kurzen Cosmographia.
