Earth, Air, Fire & Water

Empedoclean Theory The Greek philosopher Empedocles of Acragas asserts that matter consists of four elements - earth, air, fire & water - a theory that is later supported and embellished upon by Aristotle. This concept influenced the philosophical basis for the next advance in the science of matter - alchemy. The image above is based upon symbols and diagrams from various periods in history featuring the four elements.
