“…Although first introduced, explained, and patented by one Prof. Pepper (at that time, the director of London's Royal Polytechnic Institute), they were subsequently extensively promoted by a number of international fairground showmen including the original "King of Showmen", Randall Williams. While the original meaning/reference of the term phantasmagoria (as visual apparition) may have been replaced by the term's use to describe an overstimulation of the senses, one with a possibly negative valence [hinting at sensory deception/disorientation; Lynn (2006), Tresch (2011], there is also a sense that technology is involved in the realization (e.g., Adorno, 2005), be it of people, ghosts, or actors. This then links to the use of the term when describing Wagner's Gesamtkunstwerk (Daub, 2009;Joe and Gilman, 2010).…”
