In addition to the oft-remarked affinity with Moore, affinities with poets May Swenson, Stevie Smith, Emily Dickinson, Wendy Cope, and Amy Clampitt have been noted by some critics. Thus Katha Pollitt wrote that Ryan's fourth collection, "Elephant Rocks" (1997), is "Stevie Smith rewritten by William Blake" but that "Say Uncle" (2000) "is like a poetical offspring of George Herbert and the British comic poet Wendy Cope." Another reviewer of "Say Uncle" (2000) wrote of Ryan, "Her casual manner and nods to the wisdom tradition might endear her to fans of A. R. Ammons or link her distantly to Emily Dickinson. But her tight structures, odd rhymes and ethical judgments place her more firmly in the tradition of Marianne Moore and, latterly, Amy Clampitt."
