Eucatastrophe is a term coined by English writer J. R. R. Tolkien which refers to the sudden turn of events at the end of a story which ensures that the protagonist does not meet some terrible, impending, and very plausible doom. Tolkien formed the word by affixing the Greek prefix eu, meaning good, to catastrophe, the word traditionally used in classically inspired literary criticism to refer to the “unraveling” or conclusion of a drama’s plot. For Tolkien, the term appears to have had a thematic meaning that went beyond its literal etymological meaning in terms of form. In his definition as outlined in his 1947 essay “On Fairy-Stories“
Tolkien calls the Incarnation of Christ the eucatastrophe of “human history” and the Resurrection the eucatastrophe of the Incarnation.
