 The modern scientific [[periodic table of the elements]] and the understanding of [[combustion]] (fire) can be considered successors to such early models.
 
Interestingly, if one associates the modern term '[[Plasma]]' with Fire, the other three elements  correspond with the modern concept of 'states of [[matter]]', this is to say '[[Solid]]' corresponds to Earth, '[[Liquid]]' to Water and '[[Gas]]' to Air.

 The modern scientific [[periodic table of the elements]] and the understanding of [[combustion]] (fire) can be considered successors to such early models.
 
Interestingly, if one associates the modern term '[[plasma]]' with Fire -- a fairly accurate mapping, as [[flame]]s are in fact a visible plasma -- the four elements correspond to the modern '[[Phase (matter)|states of matter]]' -- [[solid]] mapping to Earth, [[liquid]] to Water, and [[gas]] to Air. However, as the ancient Greeks had no experience with other states of matter -- such as [[Bose-Einstein condensate]]s -- it is understandable that these are not represented in the classical system.
