Light-Winged Smoke

LIGHT-WINGED Smoke, Icarian bird,
  Melting thy pinions in thy upward flight,
  Lark without song, and the messenger of dawn,
  Circling above the hamlets as thy nest;
  Or else, departing dream, and shadowy form
  Of midnight vision, gathering up thy skirts;
  By night star-veiling, and by day
  Darkening the light and blotting out the sun;
  Go thou my incense upward from this hearth,
  And ask the gods to pardon this clear flame.
