How we cite our quotes: (Line)
Quote #1
Time and fevers burn away
Individual beauty from
Thoughtful children, and the grave
Proves the child ephemeral: (3-6)
This is the beginning of the speaker's focus on death. He notes that nothing lasts forever: children grow up and lose their beauty, and everyone dies eventually.
Quote #2
But in my arms til break of day
Let the living creature lie,
Mortal, guilty but to me
The entirely beautiful. (7-10)
By referring to his sleeping beloved as a "living creature," we're reminded of the fact that, one day, he will not be living. The speaker then goes on to call him "mortal;" just another reminder that we will all die some day.
Quote #3
Certainty, fidelity
On the stroke of midnight pass
Like vibrations of a bell, (21-23)
Here the speaker includes symbols of time passing – a clock and a bell – which have the effect of reminding us that time is always passing.
