• This article is a slightly revised version of a plenary panel address presented at the ‘Passages’ Symposium at the Sorbonne, Paris on the 12th of June 2019, in honor of the centenary of the birth of the American poet Robert Duncan. The article traces some of the mutual interest and influence between the poets Robert Duncan and Hilda Doolittle (H.D.), especially with regard to selected work of Duncan from the 1950s and 1960s, H.D.’s hugely influential “Trilogy” of the 1940s, as well as the origins of H.D.’s final major work “Hermetic Definition” (1961). The first page of the article features an abstract, as well as a string of key words. The article is being considered for publication by an online poetry and poetics journal.
