This collection of essays offers a variety of perspectives on John Dryden's work and its contexts. A towering literary figure in the late seventeenth and early eighteenth centuries, Dryden authored a series of highly successful plays and poems, in addition to influential essays of literary criticism.
As with all the Cambridge Companions, this is a good resource if you're writing on Dryden in general -- to bad it was absolutely no help to me in writing about Troilus and Cressida. There's some interesting stuff, and a good range of essays, though.
