A Menippean - Cynic - satire is a device for producing a specific kind of effect on the reader. Menippean satire is an active form, not a passive one: any work that produces the effect of a Menippean satire is a Menippean satire. It is the embodiment of a Cynic - of a Diogenes or a Menippus or a Lucian or a Rabelais. For centuries, it has frustrated the best efforts of critics to define it. Descriptive criteria (such as "a mixture of verse and prose") invariably fail because the form is determinedly fluid and polymorphous, and playful: it shifts its mode of attack with every change in culture
