This Norton Critical Edition is based on the Folio text of King Lear (carefully corrected prior to its printing in 1623). The editor has interpolated the best-known and most-often discussed passages from Quarto I (including the “mock-trial” scene) as is fully explained in both “A Note on the Text” and the annotations that accompany the play.“Sources” helps readers navigate King Lear’s rich history and includes the nine essential primary sources from which Shakespeare borrowed significantly in creating his play, along with two additional likely sources. “Criticism”provides thirteen major critical interpretations and three provocative adaptations and responses to King Lear. Critical interpretation is provided by Samuel Johnson, Charles Lamb, Peter Brook, Michael Warren, Lynda E. Boose, Janet Adelman, and R. A. Foakes, among others. The adaptations and responses are by Nahum Tate, John Keats, and Edward Bond. A Selected Bibliography is also included.
