Robert Fludd here depicts the correspondence between the Human (the Ape of Nature) and the Universe as the human is held by a Great Chain of Being from the hand of God (inside cloud). Higher levels of being descended from God's Heaven through the sphere of stars and planetary orbs to the sphere of the four elements. Humans were thought to contain essences of all other parts of the universe. Fludd was a proponent of alchemical medicine and the theory of correspondences was important to alchemical notions.
