Elizabethan literature saw the flowering of plays of classical tragedy, drama and comedy told in five acts, with a minimal description of the setting and focused on characters' dialogues, which was usually written in iambic pentameter. A great Elizabethan play-writer whose works had those features was William Shakespeare. Likewise, this age saw the development of many great poets that preferred writing sonnets, a poem consisting of 14 lines that followed a specific pattern, usually, a five-foot iambics rhyming, which gave the verse a rhythmical and melodious sound.
In this literally era the five-act structure was widely used, and the iambic pentameter was the chosen structure for the verses in most lines of Shakespeare's plays for example.
