The Importance of Being Earnest is Oscar Wilde's most brilliant tour de force, a witty and buoyant comedy of manners that has delighted millions in countless productions since its first performance in London's St. James' Theatre on February 14, 1895. The Importance of Being Earnest is celebrated not only for the lighthearted ingenuity of its plot, but for its inspired dialogue, rich with scintillating epigrams still savored by all who enjoy artful conversation.
