Religious satire is a form of satire that refers to religious beliefs and can take the form of texts, plays, films, and parody. From the earliest times, at least since the plays of Aristophanes, religion has been one of the three primary topics of literary satire, along with politics and sex. Satire which targets the clergy is a type of political satire, while religious satire is that which targets religious beliefs. Religious satire is also sometimes called philosophical satire, and is thought to be the result of agnosticism or atheism. Notable works of religious satire surfaced during the Renaissance, with works by Geoffrey Chaucer, Erasmus and Albrecht Dürer.
