  According to an ancient Greek philosopher, scientist and healer all matter is comprised of four elements: earth, water, fire and air and associated these four elements with gods and goddesses of Greek mythology. In more contemporary cosmologies these elements have been used to relate and contrast ideas of substance, feelings, energy and thought respectively.
