- Nothing that is can pause or stay;
The moon will wax, the moon will wane,
The mist and cloud will turn to rain,
The rain to mist and cloud again,
To-morrow be to-day.
- Henry Wadsworth Longfellow, Kéramos (1878), line 34.

- To-day what is there in the air
That makes December seem sweet May?
There are no swallows anywhere,
Nor crocuses to crown your hair
And hail you down my garden way.
Last night the full moon's frozen stare
Struck me, perhaps; or did you say
Really—you'd come, sweet Fnend and fair!
- Theopbile Marzials, Rondel.
- Rise! for the day is passing,
And you lie dreaming on;
The others have buckled their armour,
And forth to the fight have gone:
A place in the ranks awaits you,
Each man has some part to play;
The Past and the Future are nothing,
In the face of the stern To-day.
- Adelaide Procter, Legends and Lyrics.
