Fifty years should be easily perceptible, but open The New American Poetry and the shock is how ordinary it seems and thus how hard it is to sense the passage of what, after all, have been fifty very real years. When I read Donald Allen's list of great modernists at the beginning of his introduction, for a few seconds, it's as if I'm reading the present. I'll temporarily omit the opening phrase to further this temporal mirage: “American poetry has entered upon a singularly rich period, [one which] has seen published William Carlos Williams’ Paterson, The Desert Music and Other Poems, and Journey to Love; Ezra Pound's The Pisan Cantos, Section: Rock-Drill, and Thrones; H.D.'s later work culminating in her long poem Helen in Egypt; and the recent verse of E. E. Cummings, Marianne Moore, and the late Wallace Stevens.” [1] Such a list seems, in 2010, obvious: only one name, Cummings, would likely be omitted today. "The late Wallace Stevens" provides a glimmer of temporal shock, reminding us that, in 1960, Stevens would just have died and that Williams, Pound, H.D., Cummings, and Moore would still be alive.
