I presume a four-leaved clover is the "symbolic/ Leaf" Glück is looking for here? Here's At's hand holding some luck he made himself: A four-leaf clover engineered with spit--he told me he tried sweat first, but it didn't hold. (circa 2008, SD's outdoor wedding in DC; Baby Nu in the stroller.)
I've loved this poem for years and am so happy for Louise Glück's Nobel--poets so rarely get big prizes; but are there non Eurocentric writers who are being overlooked? Absolutely.
