I don't think Ron Silliman quite understands the H.D. poem, though I'm glad he pointed to it.
He overstates & overrates both the fury & the personal.
I see the poem as a balance, a conjunction of opposing forces. The poet is contemplating the contrast between the furious moralism of the Greeks (this woman betrayed her Greek husband for a Trojan & "caused" the 10-yr war) - a kind of ugly moralism - & the physical beauty of Helen - a kind of amoral beauty. These opposites form a tragic "bind", which the Greeks would like to resolve by putting her in the grave, and which Helen defies by her continuing presence - IN THE POEM ITSELF. By becoming a container of the beautiful, the poem then takes on a contemporary resonance, a kind of implicit attack on American philistine moralism. So it circles around on its pivot of balanced opposites.
Ron recognizes what he calls the "controlled" fury here - but (oddly for a Language poet!) he turns it into an occasion for speculating on the emotions & biography of the poet. I don't think that's the issue - I don't think H.D. is expressing her "fury" - she's expressing a tragic sense of life - & the agon - the "bind" - which motivates the uncanny charisma, the fascination, of works of art. Yes, of course we can always extrapolate personal aspects - but I think too often they are over-emphasized. Critics run to explain WHAT H.D. must have been furious about - something in her personal life, some social injustice - & by rationalizing the poem they only continue the philistine process of dismissing, marginalizing, & missing its IRRATIONAL (or supra-rational or inexplicable) beauty.
