Entitled: "Utriusque cosmi maioris scilicet et minoris metaphysica"; by Robert Fludd, page, 83. Fludd's philosophy is presented in 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, published in Germany between 1617 and 1621). During the 16th and 17th centuries, notions of macrocosm and microcosm were widely accepted. Many people believed that the same patterns are to be found in the human body (microcosm) on a small scale, as are found in the natural universe as a whole (macrocosm).
