Analysis of On Chloris Walking in the Snow

I saw fair Chloris walk alone,
    Whilst feather'd rain came softly down,
    And Jove descended from his tower
    To court her in a silver shower.
    The wanton snow flew on her breast
    Like little birds unto their nest;
    But overcome with whiteness there,
    For grief it thaw'd into a tear;
    Thence falling on her garment's hem,
  To deck her, froze into a gem.
