Here you will find the Poem Snake of poet Theodore Roethke
I saw a young snake glide Out of the mottled shade And hang, limp on a stone: A thin mouth, and a tongue Stayed, in the still air. It turned; it drew away; Its shadow bent in half; It quickened and was gone I felt my slow blood warm. I longed to be that thing. The pure, sensuous form. And I may be, some time.
