"Marat/Sade" is Crazy Good
“The Persecution and Assassination of Jean Paul Marat as Performed by the Inmates of the Asylum of Charenton under the Direction of the Marquis de Sade” by Peter Weiss, commonly known as "Marat/Sade" is perhaps the ultimate play within a play.
The audience members are informed when the play begins that they are about to watch the inmates of Charenton perform a historical play written about the death of Jean Paul Marat written by the Marquis de Sade.
All of the inmates of Charenton who participate in the play suffer from diseases; the inmate playing Charlotte Corday, for example, suffers from “Sleeping Sickness”, and the fellow playing Marat is paranoid and delusional. We are informed that the play is intended to serve as art therapy, for everyone who participates, including the Marquis de Sade, who also serves as director.
