I love book-length poems: the long arc, the immersion, some of the pleasures of a novel combined with the repetition of images, the hypnotic pull forward. Like living in a house instead of a series of rooms, maybe. A world in a book. As Stevens said, a planet on the table. Some of my own favorites, right off the top of my head: C. D. Wright’s Deep Step Come Shining, Louise Gluck’s The Wild Iris and Faithful and Virtuous Night, Derek Walcott’s epic Omeros, Ellen Bryant Voigt’s Kyrie, Allen Ginsberg’s Kaddish. What comes to your mind?
