Doppelgänger

A double or look-alike whose resemblance creates uncanny parallels or mistaken identity. In fiction and folklore, a doppelgänger often signals a fractured identity or ominous fate.

Uncanny: An unsettling feeling produced when something familiar seems strange or ambiguously alive. A double makes the familiar face uncanny by separating appearance from identity.
The Double (Dostoevsky novel): Fyodor Dostoevsky’s 1846 novella about a civil servant displaced by his socially successful double. Golyadkin’s double turns social insecurity into a struggle over who counts as the original.
German folklore: Traditional stories, beliefs, and customs associated with German-speaking communities. The doppelgänger entered wider culture through German-language folklore and literature.
Look-alike: A person who closely resembles another person in appearance. Ordinary resemblance needs no uncanny parallel or supernatural interpretation.
Identity: The qualities and relations through which a person or thing is recognized as itself. Doppelgängers unsettle the assumption that appearance reliably identifies a person.
The Strange Case of Dr Jekyll and Mr Hyde: Robert Louis Stevenson’s 1886 novella about a doctor whose experiments divide his respectable and violent selves. Jekyll and Hyde make the double an embodied split within one person.
Romanticism: An artistic and intellectual movement that emphasized emotion, imagination, nature, and individual experience. Romantic-era writing made the double a vehicle for inner conflict and uncanny experience.
Doppelganger (folklore): A supernatural double whose appearance is traditionally treated as an omen or portent. Folklore gives the double an independent, often ominous existence beyond resemblance.
Narcissus: A figure in Greek mythology who falls in love with his reflection and dies beside it. The myth makes self-recognition through a double a source of danger.
The Student of Prague: A 1913 German silent film about a student whose reflection becomes an independent double. Its stolen reflection gives the doppelgänger a literal visual form.
