In Rev 16.13–14 we encounter minor characters of the book's diabolic bestiary, ‘three unclean spirits like frogs’ that proceed from the mouths of the Dragon and the two Beasts. This article attempts to understand this detail in relation to the metaphorical connotations other ancient Greek and Jewish writers attributed to frogs: they were mostly connected with silliness and loquaciousness. In this context, the picturesque detail of frog-like demons belongs to John's strategy of reassuring his audiences by ridiculing the Dragon and the Beasts and the powers they represent.
