In narratology, focalisation (also focalization) is the perspective through which events in a narrative are perceived and presented to the reader. The concept was introduced by French narrative theorist Gérard Genette to replace the vaguer notion of "point of view" by separating the question of who sees (the focaliser) from who speaks (the narrator). Genette distinguished three types: zero focalisation (an omniscient narrator whose knowledge exceeds that of any character), internal focalisation (the narrative is filtered through a character's consciousness), and external focalisation (the narrator reports only what is externally observable, knowing less than the characters).
The concept was substantially refined by Mieke Bal, who recast focalisation as a relationship between a focaliser (the agent whose perception orients the narrative) and the focalised (the object of that perception). Focalisation has become one of the central analytical categories in narratology, with applications in literary criticism and film studies.
Genette proposed focalisation as part of the category of mood (mode) in his systematic framework for narrative analysis. He distinguished three types based on the relationship between the narrator's knowledge and the characters' knowledge:
Genette noted that these types rarely appear in pure form throughout an entire work; most narratives involve shifts or combinations of focalisation, and "any single formula of focalization does not, therefore, always bear on an entire work, but rather on a definite narrative section."
Mieke Bal argued that Genette's typology conflated the subject and object of perception. In her reformulation, focalisation is a relationship between two entities:
Bal further distinguished between a character-bound focaliser (internal to the story, yielding a subjective perspective) and an external focaliser (outside the story, producing a more detached view). This two-level model allows analysts to ask not only through whom the reader perceives, but also what is being perceived, and with what degree of subjective colouring.
Bal's refinement has been influential but also debated. Genette himself responded critically in Narrative Discourse Revisited (1988), defending his original categories while acknowledging some of Bal's points.
Focalisation overlaps with but is distinct from several related narratological concepts:
