The term EARTH, AIR, FIRE OR WATER is a reference to the four classical elements of ancient Greek philosophy. These elements were believed to be the fundamental components of all matter and were thought to be the building blocks of the universe. Earth was seen as the solid foundation of the world, air was seen as the breath of life, fire was seen as the source of energy and water was seen as the source of life. Each ELEMENT was believed to have its own unique properties and characteristics.
