Euphuism is a peculiar mannered style of English prose. It takes its name from a prose romance by John Lyly. It consists of a preciously ornate and sophisticated style, employing a deliberate excess of literary devices such as antitheses, alliterations, repetitions and rhetorical questions. Classical learning and remote knowledge of all kinds are displayed. Euphuism was fashionable in the 1580s, especially in the Elizabethan court. Its origins can be traced back to Spanish writer Antonio de Guevara, whose ornate, manierist courtesan prose became very popular throughout Europe, and whose work The Clock of the Princes, translated into English in 1557 by Thomas North, reached its peak in popularity during Elizabeth I's reign.

John Lyly was an English writer, playwright, courtier, and parliamentarian. He was best known during his lifetime for his two books Euphues: The Anatomy of Wit (1578) and its sequel Euphues and His England (1580), but is perhaps best remembered now for his eight surviving plays, at least six of which were performed before Queen Elizabeth I. Lyly's distinctive and much imitated literary style, named after the title character of his two books, is known as euphuism. He is sometimes grouped with other professional dramatists of the 1580s and 1590s like Christopher Marlowe, Robert Greene, Thomas Nashe, George Peele, and Thomas Lodge, as one of the so-called University Wits. He has been credited by some scholars with writing the first English novel, and as being 'the father of English comedy'.
