Boullée, Cénotaphe a Newton (1784)

Étienne-Louis Boullée (1728 –1799) was a visionary French neoclassical architect whose work greatly influenced contemporary architects and is still influential today.
Boullée promoted the idea of making architecture expressive of its purpose, a doctrine that his detractors termed architecture parlante (“talking architecture”), which was an essential element in Beaux-Arts architectural training in the later 19th century.
