Narratology is the study of narrative and narrative structure and the ways that these affect our perception. While in principle the word may refer to any systematic study of narrative, in practice its usage is rather more restricted. It is an anglicisation of French narratologie, coined by Tzvetan Todorov (Grammaire du Décaméron, 1969). Narratology is applied retrospectively as well to work predating its coinage. Its theoretical lineage is traceable to Aristotle (Poetics) but modern narratology is agreed to have begun with the Russian Formalists, particularly Vladimir Propp (Morphology of the Folktale, 1928).
The origins of narratology lend to it a strong association with the structuralist quest for a formal system of useful description applicable to any narrative content, by analogy with the grammars used as a basis for parsing sentences in some forms of linguistics. This procedure does not however typify all work described as narratological today; Percy Lubbock's work in point of view (The Craft of Fiction, 1921) offers a case in point.
In 1966 a special issue of the journal Communications proved highly influential, becoming considered a program for research into the field and even a manifesto. It included articles by Barthes, Claude Brémond, Genette, Greimas, Todorov and others, which in turn often referred to the works of Vladimir Propp (1895-1970).
