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 believed that it had one of the three most perfect plots in literature. The play's clever fulfilment of the classical unities and vivid depiction of human folly have made it one of the few Renaissance plays with a continuing life on stage, apart from a period of neglect during the Victorian era.
