I was rereading Virtu when I read The Wasteland a couple weeks ago in my lit class, and the line "And the dead tree gives no shelter, the cricket no relief" struck me as very similar to part of the huphantike: "the dead tree will not shelter you, and the dead will not stay dead." Seeing as you took other influences from the poem, was I right to assume this had also been taken from Eliot?
