Analysis of New-Year's Eve

As when at twelve o'clock
Strong January opes the gates of Life
And we that were so cabined and so dark
Within the round tower of the rounded year
Feel the far Spring blown in on us and look
Straight to the primroses, and with the swallow
Skim thro' the dawns of daffodils and up
To bluebell skies, and from the bluebell skies,
Like a wild hawk upon a flight of doves,
Swoop upon June and Paradise, and on
Beyond the bounds of Eden to an Earth
Boss'd with great purples of new-clustered wine
Betwixt the tented harvests red and gold,
And so into a cloud, and know no more--
