William Shakespeare wrote at least two plays that are completely lost.

In 1598, a writer named Francis Meres listed a play called 'Love's Labour's Won' in his book. No physical copy of this play has ever been found. Some experts think it was a sequel to another play. Others believe it was just a different name for 'Much Ado About Nothing'.Another missing play is 'Cardenio'. Records show a theater group called the King’s Men performed it in 1613. Shakespeare likely wrote it with another writer named John Fletcher. The story was based on a famous book called 'Don Quixote'.In 1727, a man named Lewis Theobald released a play called 'Double Falsehood'. He claimed he used Shakespeare's lost 'Cardenio' script to write it. Modern computer tests show that some of the writing style matches Shakespeare's work. However, the original 1613 version is still missing.During the 1500s and 1600s, plays were written for actors to perform rather than for people to read. Only about 15% of all plays from that time survived. Most were lost to fires, dampness, or neglect. These missing plays leave gaps in what we know about the world's most famous playwright.
