In the first part of Foakes’s introduction, the editor examines King Lear as it is read in the mind versus how it is performed on the stage, analyzing historical productions and certain elements of the play that shine in performance but not in text, and vice versa. This section also explores how and why the play has invited so many interpretations, in reading and performance, since its inception. The next part of the introduction considers trends in the criticism and staging of the play, such as the recent shift of favor from redemptive to bleak readings. Foakes then addresses the dating of the play, the differences among the Quarto and Folio texts, and whether these changes are mere discrepancies or intentional revisions. Finally, the editor discusses the casting of the play and explains notable usages in his edition. There are two appendices that follow the play: the first examines two textual problems that are particularly difficult to interpret, and the second explains differences in lineation between the Quarto and Folio editions, which resulted from confusion whether certain lines were in prose or verse. This edition also includes lists of illustrations, abbreviations, and references, as well as a general editors’ preface and an index.
