Two couples-Benedick and Beatrice, and Hero and Claudio-must overcome deception, gossip, and, occasionally, their own misplaced pride if their love is to persevere. Aided by military commander Don Pedro and impeded by his brother Don John, the friends go to great lengths in the pursuit of marriage. Known as "The Bard of Avon," William Shakespeare is arguably the greatest English-language writer known. Enormously popular during his life, Shakespeare's works continue to resonate more than three centuries after his death, as has his influence on theatre and literature. Shakespeare's innovative use of character, language, and experimentation with romance as tragedy served as a foundation for later playwrights and dramatists, and some of his most famous lines of dialogue have become part of everyday speech.
