Oscar Wilde's voice is unique. His acerbic wit is iconic and instantly recognizable to those familiar with his work. Due to his distinctive style, many of his works are similar in tone. The Importance of Being Earnest most closely resembles his other three most famous comedies--Lady Windemere's Fan, A Woman Of No Importance and An Ideal Husband. All four are comedies that satire London's high society with Wilde's quintessential wit.
This may be made clearer in reading plays by Wilde's contemporaries, such as George Bernard Shaw or the operetta-writing duo W.S. Gilbert and Arthur Sullivan.
