There aren't many words in H.D.'s poems, but the words that are there pack a punch. H.D. is known for doing more with less, and she was one of the founders of the Imagist movement of poetry, which was focused on vivid imagery (check!) and an economy of language (check!).
If you're digging H.D.'s short and intense "Helen," you might want to check out her similarly short and intense "Sea Rose". It's a quick one, and its plain language belies its complex issues—just as "Helen" does.
