Aristotlewho had been Plato's student at the Academyagreed on this point with his former mentor, emphasizing additionally that fire has sometimes been mistaken for aether.

The symbols were in common use through the 17th century, and some are still in use today.

These different cultures and even individual philosophers had widely varying explanations concerning their attributes and how they related to observable phenomena as well as cosmology. Sometimes these theories overlapped with mythology and were personified in deities. Some of these interpretations included atomism the idea of very small, indivisible portions of matter , but other interpretations considered the elements to be divisible into infinitely small pieces without changing their nature.
