This edition was rewritten and expanded from the first edition in quarto. Kircher's definitive work on magnetism and electromagnetism (a term coined by Kircher in this work), which he conceived as a universal force of nature. Kircher carefully compiled measurements of magnetic declination from several places around the world, as reported by Jesuit scholars, and particularly by his disciple Martin Martine, who in a letter suggested the possibility of determining longitudes by the declination of a magnetic needle. Recognizing the importance of this method, Kircher brought it to the attention of the scientific world. An extensive chapter discusses the magnetic properties of the planets. Kircher's Magnes is filled with curiosities, both profound and frivolous. The work does not deal solely with what modern physicists call magnetism. Kircher discusses, for example, the magnetism of the earth and heavenly bodies; the tides; the attraction and repulsion in animals and plants; and the magnetic attraction of music and love. He also explains the practical applications of magnetism in medicine, hydraulics, and even in the construction of scientific instruments and toys. In the epilogue Kircher moves from the practical to the metaphysical - and Aristolelian - when he discusses the nature and position of God: "the central magnet of the universe." Practically all of Kircher's works begin with an illustrated title-page. Sometimes these were changed even for later issues of the same work, as for this second and greatly enlarged edition of his Magnes. Sommervogel IV 1048.6; Merrill 5.
