For The New Yorker, Stephanie Burt examines how the work of poet Seamus Heaney became synonymous with happiness and joy—and how it came to be quoted by presidents and casual readers alike. “It is this later, happier Heaney who comes into his own in his family’s idiosyncratic selection. Almost buoyant, occasionally repetitive, surprised by himself at least as often as he surprised readers, this Heaney remained self-conscious, revisiting and answering earlier verse. ‘The Conway Stewart’ is a fancy pen, the first the poet owned, and the sharp-lined, short-lined poem of that name returns to a three-way comparison in ‘Digging’ (the first poem in his first book), between spade and pen and gun.”
