Boullée, Cénotaphe a Newton (1784)

Étienne-Louis Boullée’s style was most notably exemplified in his proposal for a cenotaph for the English scientist Isaac Newton, which would have taken the form of a sphere 150 m (500 ft) high embedded in a circular base topped with cypress trees. Though the structure was never built, its design was engraved and circulated widely in professional circles.
