Analysis of The Old Moon In The New Moon's Arms

The beautiful and slender young New Moon,
 In trailing robes of pink and palest blue,
Swept close to Venus, and breathed low: 'A boon,
 A precious boon, I ask, dear friend, of you.'

'O queen of light and beauty, you have known
 The pangs of love - its passions and alarms;
Then grant me this one favour, let my own -
 My lost Old Moon be once more in my arms.'

Swift thro' the vapours and the golden mist -
 The Full Moon's shadowy shape shone on the night,
The New Moon reached out clasping arms and kissed
 Her phantom lover in the whole world's sight.
