This study shows how playwrights in the early modern Low Countries undermined their contemporaries' belief in the magical power of language. This is evident in the way they depicted and ridiculed exorcism rituals in their farces. Such rituals were seen in the early modern period as 'administering' inherently powerful words to a beneficiary. This view is also reflected in a contemporary 'speech act theory' avant la lettre, which attributes to spoken words the ability to interact on their own accord with other forces in the universe, regardless of the authority or intention of the speaker. The farcical exorcisms served not only to ridicule Roman Catholic rituals and their underlying demonic beliefs, or to make a show of the bizarre behavior of possessed individuals and devil banners. Their creators also took a stand against the idea that language possessed autonomous powers, and instead argued for a view of language as a fully human-made and human-controlled instrument.
