The word "diorama" originated in 1823 as a type of picture-viewing device, from the French in 1822. The word literally means "through that which is seen", from the Greek di- "through" + orama "that which is seen, a sight". The diorama was invented by Louis Daguerre and Charles Marie Bouton, first exhibited in Paris in July 1822 and at The Diorama, Regent's Park on September 29, 1823. The meaning "small-scale replica of a scene, etc." is from 1902.
