Dissecting Leonardo's Anatomy
 

Dissect by Macro- and Microcosm On the macrocosm and microcosm: "Man has been called by the ancients a lesser world, and indeed the term is rightly applied, seeing that if man is compounded of earth, water, air and fire, this body of the earth is the same; and as man has within himself bones as a stay and framework for the flesh, so the world has the rocks which are the supports of the earth; as man has within him pool of blood wherein the lungs as he breathes expand and contract, so the body of the earth has its ocean, which also rises and falls every six hours with the breathing of the world [the tides]; as from the said pool of blood proceed from the veins which spread their branches through the human body, in just the same manner the ocean fills the body of the earth with an infinite number of veins of water" (qtd. in Gould 31).
