Bathos (Greek βάθος, meaning depth) is an abrupt transition in style from the exalted to the commonplace, producing a ludicrous effect. While often unintended, bathos may be used deliberately to produce a humorous effect. If bathos is overt, it may be described as Burlesque or mock-heroic. As used in English bathos originally referred to a particular type of bad poetry, but it is now used more broadly to cover any seemingly ridiculous artwork or bad performance. It should not be confused with pathos, a mode of persuasion within the discipline of rhetoric, intended to arouse emotions of sympathy and pity.
