The novel’s depiction of Victorian London seems to draw a lot from the historical events and fashions of the era. Dorian’s excursion into the seedy world of opium dens especially relates to an underground city obsession.
Other works of the 19th century that deal with Gothic settings and spooky, supernatural events: like Mary Shelley’s Frankenstein and The Tell-Tale Heart by Edgar Allan Poe. For its dark portrayal of opium and temptation-filled London, Charles Dickens’ The Mystery of Edwin Drood also creates a similar atmosphere.
