Sonnet 126

Written in 1594, Sonnet 126 is one of 154 sonnets by the English playwright and poet William Shakespeare. It's the final member of the Fair Youth sequence, in which the poet shows how Time and Nature coincide.

Sonnet 126 O thou, my lovely boy, who in thy power

O thou, my lovely boy, who in thy power
Dost hold Time's fickle glass, his sickle, hour;
Who hast by waning grown, and therein show'st
Thy lovers withering as thy sweet self grow'st;
If Nature, sovereign mistress over wrack,
As thou goest onwards, still will pluck thee back,
She keeps thee to this purpose, that her skill
May time disgrace and wretched minutes kill.
Yet fear her, O thou minion of her pleasure!
She may detain, but not still keep, her treasure:
Her audit, though delay'd, answer'd must be,
And her quietus is to render thee. 

Paraphrase: O you, my lovely boy, who hold in your power Time’s hour-glass and his sickle—you who wane as you grow older and in that show your friends withering as you yourself grow up: if Nature, sovereign mistress over chaos, as you go onwards will ever pluck you back, she keeps you to demonstrate her power to hold up time. Yet fear her, you who are Nature’s darling: she may detain her treasure, but not keep it for ever. Her last account, though delayed, must be paid and her discharge is to render you up.
