NUDE DESCENDING A STAIRCASE - by X.J. KENNEDY Toe upon toe, a snowing flesh, A gold of lemon, root and rind, She sifts in sunlight down the stairs With nothing on. Nor on her mind. We spy beneath the banister A constant thresh of thigh on thigh-- Her lips imprint the swinging air That parts to let her parts go by. One-woman waterfall, she wears Her slow descent like a long cape And pausing, on the final stair Collects her motions into shape.
