Which excerpt highlights the theme of the fleeting nature of life?

But at my back I always hear

Time's winged chariot hurrying near,

And yonder all before us lle

Deserts of vast eternity

(Andrew Marvell, "To His Coy Mistress)

And poppy or charms can make us sleep as well

And better than thy stroke; why swell'st thou then?

One short sleep past, we wake eternally

And death shall be no more; Death, thou shalt die

(john Donne, Sonnet 10)

of what is fit and not. Forsake thy cage,

Thy rope of sands,

Which petty thoughts have made, and made to thee

(George Herbert, "The Collar)

Thy beams, so reverend and strong

Why shouldst thou think?

I could eclipse and doud them with a wink,

But that I would not lose her sight so long

John Donne, "The Sun Rising
