Helen Vendler has become one of our most trusted companions in reading poetry. Among critics today she has an unrivaled ability to show--lucidly and invitingly--just what a poem does. Insight and wit distinguish these essays, in which Vendler elucidates the function of criticism as well as different critical methods and styles. Poets commented on range from Seamus Heaney and Czeslaw Milosz to Silvia Plath, James Merrill, and Amy Clampitt.
