The Alchemist is a comedy by English playwright Ben Jonson. First performed in 1610 by the King's Men, it is generally considered Jonson's best and most characteristic comedy; Samuel Taylor Coleridge claimed that it had one of the three most perfect plots in literature. The play's clever fulfillment of the classical unities and vivid depiction of human folly have made it one of the few Renaissance plays (except the works of Shakespeare) with a continuing life on stage (except for a period of neglect during the Victorian era).
