The classic example in western architecture of the historical progression of an architectural idea which grows from technology - in this case the technical necessity of creating a platform on which to support stone beams on the top of a stone column in ancient Greek construction. The design of column capitols can be traced from the conceptual birth of the architectural idea [Doric Capital on the left], to full development and maturity of the idea [Ionic Capital in the center], to over-elaboration, where there is nothing new added because the basic idea has been exhausted and invention has slipped into decadance [Corinthian Capital on the right].
