He believed that a bastardisation of his vision had taken place that amounted to a commoditisation of the body he had tried to deny in his trilogy in the first place. The disconsolation this provided is seen as one of the primary reasons for his final film, "Salò", in which humans are not only seen as commodities under authoritarian control but are viewed merely as ciphers for its whims, without the free vitality of the figures in the Trilogy of Life. His final work, "Salò" ("Salò, or the 120 Days of Sodom", 1975), exceeded what most viewers could accept at the time in its explicit scenes of intensely sadistic violence. Based on the novel "120 Days of Sodom" by Marquis de Sade, it is considered Pasolini's most controversial film. In May 2006, "Time Out"'s Film Guide named it the "Most Controversial Film" of all time. Salò was intended as the first film of his "Trilogy of Death", followed by an aborted biopic film about Gilles de Rais. As a director, Pasolini created a picaresque neorealism, showing a sad reality. Many people did not want to see such portrayals in artistic work for public distribution. "Mamma Roma" (1962), featuring Anna Magnani and telling the story of a prostitute and her son, was an affront to the public ideals of morality of those times. His works, with their unequaled poetry applied to cruel realities, showing that such realities were less distant from most daily lives, and contributed to changes in the Italian psyche. Pasolini's work often engendered disapproval perhaps primarily because of his frequent focus on sexual behavior, and the contrast between what he presented and what was publicly sanctioned. While Pasolini's poetry often dealt with his gay love interests, this was not the only, or even main, theme. His interest in and use of Italian dialects should also be noted. Much of the poetry was about his highly revered mother. He depicted certain corners of the contemporary reality as few other poets could do. His poetry, which took some time before it was translated, was not as well known outside Italy as were his films. A collection in English was published in 1996. Pasolini also developed a philosophy of language mainly related to his studies on cinema. This theoretical and critical activity was another hotly debated topic. His collected articles and responses are still available today. These studies can be considered as the foundation of his artistic point of view: he believed that the language—such as English, Italian, dialect or other—is a rigid system in which human thought is trapped.
