Since Robert Lowell’s sudden death in 1977 his critical reputation has suffered from the usual post-mortem slump. Interest in Lowell’s life, however, remains as strong as during his celebrity heyday, when he graced the cover of Time magazine and marched on the Pentagon with Norman Mailer. A biography (excellent, by Ian Hamilton), an edition of his letters, and a volume of the correspondence between Lowell and Elizabeth Bishop are all firmly in print.
