The fourth in a series of editions of Shakespeare’s most political and history-soaked plays, this Macbeth offers copious aids to understanding the play not found in any other edition. By attending to the play’s medieval Scottish setting in a way that rival editors have never matched—when they have even dug beyond the early seventeenth-century context in which it was produced—Jan H. Blits’s edition richly rewards readers left unsatisfied by “decodings” of the play’s supposed allusions to the politics of early modern England who wish to look deeper. In doing so, it opens the text for readers to encounter, in new ways, the play’s historical, political, and psychological significance.
