Microcosm
Microcosm(from a Greek compound of μικρο- "Micro-", which means “small”, and the word κόσμος kósmos which means "order" as well as "world" or "ordered world.") is a Western philosophical term. Man was seen as a microcosm and the universe as a macrocosm. Man and the universe are constructed according to the same harmonic proportions. All of the characteristics of the world can be found on the human body and the characters of men can also be found from the earth: the stars in the sky not only influence every little world- people's lives, including birth, death, destiny and all daily sorts of incident, and his hobbies, interests, temperament, personality, but also even affect the country's rise and fall, dynastic chronology, the outcome of the war, economic prosperity and decline. That explains why many people in the Renaissance thought the planets could influence their lives. That man is the microcosm was, in the Renaissance, widely taken to mean that cosmic knowledge and influence might be achieved through contemplation of the powers and tendencies men find in their own imaginations. So were hierarchies and order very important in the Renaissance culture.
