Could e'er be beautiful? yet so they were,
  And that with little change of shape or hue;
  All things had put their evil nature off;
  I cannot tell my joy, when o'er a lake,
  Upon a drooping bough with nightshade twined,
  I saw two azure halcyons clinging downward
  And thinning one bright bunch of amber berries,
  With quick long beaks, and in the deep there lay
  Those lovely forms imaged as in a sky;
  So with my thoughts full of these happy changes,
  We meet again, the happiest change of all.

ASIA
  And never will we part, till thy chaste sister,
  Who guides the frozen and inconstant moon,
  Will look on thy more warm and equal light
  Till her heart thaw like flakes of April snow,
  And love thee.

SPIRIT OF THE EARTH
  What! as Asia loves Prometheus?

ASIA
  Peace, wanton! thou art yet not old enough.
  Think ye by gazing on each other's eyes
  To multiply your lovely selves, and fill
  With spherèd fires the interlunar air?
