Legend of Heraclitus NFT
The Three element theory asserts that the universe is comprised for three primary elements, namely: earth, water, and fire, and that among these fire is the fundament or underlying essential nature of earth and water. The three element theory was introduced by Greek philosopher Heraclitus, in circa 500BC, supposedly derived in some way from the Egyptian Heliopolis creation myth, according to which the universe resulted from a primordial abyss from which fire (Ra) burst forth thereafter self-engendering earth (Geb) and water (Nun).
