Book excerpt: Literary Theory and Criticism: An Introduction provides an accessible overview of major figures and movements in literary theory and criticism from antiquity to the twenty-first century. It is designed for students at the undergraduate level or for others needing a broad synthesis of the long history of literary theory. An introductory chapter provides an overview of some of the major issues within literary theory and criticism; further chapters survey theory and criticism in antiquity, the Middle Ages and Renaissance, the Enlightenment, and the nineteenth century. For twentieth- and twenty-first-century theory, the discussion is subdivided into separate chapters on formalist, historicist, political, and psychoanalytic approaches. The final chapter applies a variety of theoretical concepts and approaches to two famous works of literature: William Shakespeare’s Hamlet and Mary Shelley’s Frankenstein.
