Title page of the 1617 work Utriusque Cosmi, Maioris scilicet et Minoris, metaphysica, physica, atque technica Historia (The metaphysical, physical, and technical history of the two worlds, namely the greater and the lesser) by the English physician, astrologer, and mystic Robert Fludd (1574-1637). The Latin text gives the book's title, the name of the author, and a description of the contents. The artwork at bottom shows Fludd's theory of the microcosm and the macrocosm, with a human figure straddling the microcosm (the inner world), surrounded by the macrocosm (the outer world).
