Pleorama
The best-known pleorama was a 19th-century moving panorama entertainment where the viewers sat in a rocking boat while panoramic views on painted canvas rolled past. The word has sometimes been used for other entertainments or innovations. Architect Carl Ferdinand Langhans introduced a pleorama in Breslau in 1831 with scenes of the Bay of Naples on both sides of 24 "voyagers" sitting in a wooden boat floating in a pool of water. The illusion was enhanced by light and sound effects: the boatman singing, Vesuvius erupting. Writer/artist August Kopisch was involved in designing the hour-long show.
