That time of year thou mayst in me behold When yellow leaves, or none, or few, do hang Upon those boughs which shake against the cold, Bare ruin'd choirs, where late the sweet birds sang.
In me thou see'st the twilight of such day As after sunset fadeth in the west; Which by and by black night doth take away, Death's second self, that seals up all in rest.
In me thou see'st the glowing of such fire, That on the ashes of his youth doth lie, As the death-bed, whereon it must expire, Consum'd with that which it was nourish'd by.
This thou perceiv'st, which makes thy love more strong, To love that well, which thou must leave ere long.
It is a case of Hyperbaton because the normal order of words has been changed.
That time of year thou mayst in me behold .
When yellow leaves, or none, or few do hang .
This is a case of Metaphor since the poet compares his present condition to the season of winter. This comparison is not stated explicitly.
This is also a metaphor in another sense because the ‘sweet birds’ not only refer to the literal birds but also to the ,choir singers in the church.
In me thou see’st the twilight of such day
As after sunset fadeth in the west .
This is a case of Metaphor since the poet’s condition has been compared to taillight.
It may also be a case of simile because the comparison between the poet and the condition after the fading of the sun is stated explicitly by the use of the word ‘as’.
In me thou seest the glowing of such fire
This is a case of Metaphor . Here the poet compares his present condition to those glowing embers which are about to be extinguished.
