Microcosm and Macrocosm in the Renaissance

The idea of a microcosm-macrocosm correspondence is fundamental in the Renaissance interpretation of the world. To reach a better understanding of Renaissance natural philosophy, but also astrology, medicine, and in general the strong relation between many different sciences, is important to know how microcosm, plants, minerals, and animals, and macrocosm, planets and stars, are related. In medicine, in particular, the human body is considered a microcosm in its own right and knowing the correspondence between its parts and macrocosm was a fundamental requirement for the healing process.
