Vicarious lives, the alter egos of unwritten or belatedly written poems, trap doors into hitherto unseen aspects of a personality, feints and personae—poets’ letters can be and have been all these and more, and the all-star lineup of critics, poets and essayists here demonstrate. This collection isn’t just the last word so far on a topic (two topics, at least) or permanent interest, but an example for literary critics in general: Anne Fadiman’s defense of Hartley Coleridge, Paul Muldoon on Bishop and (or Bishop vs.) Lowell, Michael Hurley on humour in Hopkins, Ellis himself on frustration and temporality in Bishop and Keats—here is a model for writers. And for readers. And for letter-writers, scholarly and otherwise, everywhere.
