‘The wave always returns’, writes Marina Tsvetaeva. And it ‘always returns as a different wave’. Such Color reveals such a relentless renewal of lyricism as a signature of Tracy K. Smith’s poetry. A selected edition promises to highlight images and ideas across the American poet’s work. For Smith, one constant is the movement of water. In ‘Minister of Saudade’, from her second collection, Duende (2007), the speaker asks: ‘What kind of game is the sea?’ After a pause at the stanza break, an incantatory reply comes: ‘Lap and drag. Crag and gleam. / The continual work of wave / And tide.’ Ceaseless making, flux, and patterning are also a poem’s work. Smith’s image of creative marine energy recalls Sylvia Plath’s image of words’ ‘indefatigable hooftaps’, echoing as they carry meaning outwards. In Plath’s case, as in Smith’s, one direction is seawards.
