The sophisticatedly constructed novel "The Strange Case of Dr. Jekyll and Mr. Hyde" was conceived in 1886, during the revolutionary Victorian era, by author Robert Louis Stevenson. Stevenson developed a desire to write early in life, and "Dr. Jekyll and Mr. Hyde" cemented his reputation. The novel is widely known for its shocking principles that terrified and alarmed Victorian readers. 'Dr Jekyll and Mr Hyde' plays with the idea of ​​man's dual nature, of his two identities. On the surface, Dr. Jekyll is a conventional Victorian gentleman, but beneath the surface lurks the primitive and satanic creature of Mr. Edward Hyde. One of the elements that play a significant role in the novel is the setting. Stevenson subtly uses the setting to portray the atmosphere throughout the book. The novel focuses on Victorian London, during the industrial revolution. The very British and civilized behavior on the surface masked the uncivilized life beneath. London was a heavily polluted city, submerged in thick, heavy smog. As a result, it was a brilliant location to base a Gothic novel. Another reason why setting it in London was suitable was the closeness between rich and poor. The rich used their positions of power to exploit society's poorer citizens, but despite their superiority, they still felt threatened by the close proximity of the poor. Stevenson uses the position effectively to represent the duplicity of his own nature. For example, the front entrance to Dr. Jekyll's house is traditionally Victorian, but the back entrance, used by the troglodyte character Hyde, is depicted with "marks of prolonged and sordid neglect", representing the dishonorable deeds taking place there. interior of the house. .... half of the sheet ...... feelings of tension, aggression and violence.- and of evil prevailing over good. The originality and ingenuity of the novel mean that it is still popular today (there were over 123 produced film versions of the book). The book covers many scary principles, for example the concept of regression. Victorian society was afraid of Darwin's theory that animals evolved from monkeys, so the book struck fear into the hearts of many people. It raises the idea of ​​supernatural beings and what the Victorians feared most of all, that God is powerless. It can be interpreted that psychoanalyst Sigmund Freud's divisions were influenced by the portrayal of Mr. Hyde and Dr. Jekyll in the novel. Therefore, when Stevenson wrote the book, he had to express these principles, and the setting was one of the crucial ways he used to convey the turbulent battle between good and evil..
