Belived that atoms were made of four basic elements:

Fire
 
Water
 
Air
 
Earth
 
All things in the world were made up of different combinations of these four elements.  The elements were affected by gravity and levity which are the tendency to sink or rise.  Aristotle was alive during the Greek empire, and though his theory was the most poular another man, Democritus had already suggested that all things were made of atoms.
 
Aristole's theory also relied on to forces:
Harmony casued everything good
Conflict caused everytinhg bad
The heavens were made of Aither, the sacred element.
 
Aristotles thory whould remain unchallenged until the scientific revolution.
