This paper will delve into the similarities between Patrick Bateman, the modern day libertine of Wall Street, and the four essential characters of Marquis De Sade’s, “120 Days of Sodom”. My preparation for this paper includes a light reread of 120 Days, watching the film, “Salo”, and reading and watching “American Psycho”. Through this paper I hope to uncover the elements of ultimate power, sexual fantasies, and murder that intersect the times these two books were written. 120 Days of Sodom was was written during the French Revolution, while American Psycho was written in 1991 but takes place during Reagan-era capitalist New York. There is an essential theme in both books of hidden identities, and personification of job titles. For example, Patrick Bateman is a Wall Street banker and his temperament is very violent, cold, and calculated. Bateman cares deeply about his appearance – so much so that it consumes his daily life. This theme manifests itself in 120 Days through the libertines, whose physical and sexual descriptions echo their job titles in life, such as the bishop who is described to have a disgusting mouth alluding to the distain for the words of God being spoken. The painstaking descriptions of procedures and rituals rings true for both books as the order of events and way of execution for these character is highly important. Even upon one of the first scenes in American Psycho, Bateman goes into great detail on his morning routine. This is also present in 120 Days of Sodom when describing their process of sexual acts and the schedule for each day in the castle.
