<P> In Central and Eastern Europe, the style is usually referred to as Classicism (German: Klassizismus), while the newer revival styles of the 19th century until today are called neoclassical . </P> <P> Intellectually, neoclassicism was symptomatic of a desire to return to the perceived "purity" of the arts of Rome, to the more vague perception ("ideal") of Ancient Greek arts and, to a lesser extent, 16th - century Renaissance Classicism, which was also a source for academic Late Baroque architecture . </P> <P> Many early 19th - century neoclassical architects were influenced by the drawings and projects of Étienne - Louis Boullée and Claude Nicolas Ledoux . The many graphite drawings of Boullée and his students depict spare geometrical architecture that emulates the eternality of the universe . There are links between Boullée's ideas and Edmund Burke's conception of the sublime . Ledoux addressed the concept of architectural character, maintaining that a building should immediately communicate its function to the viewer: taken literally such ideas give rise to "architecture parlante". </P> <P> A return to more classical architectural forms as a reaction to the Rococo style can be detected in some European architecture of the earlier 18th century, most vividly represented in the Palladian architecture of Georgian Britain and Ireland . </P>
