As his wife, Emilia must know Iago better than anybody else. She does not know, any more than the others, that he is malevolent, but she does know that her husband is addicted to practical jokes. What Shakespeare gives us in Iago is a portrait of a practical joker of a peculiarly appalling kind, and perhaps the best way of approaching the play is by a general consideration of the Practical Joker.
