But from thine eyes my knowledge I derive,

And constant stars in them I read such art

As truth and beauty shall together thrive

If from thy self, to store thou wouldst convert: 

Or else of thee this I prognosticate,

Thy end is truth's and beauty's doom and date.

When I consider every thing that grows

Holds in perfection but a little moment.

That this huge stage presenteth nought but shows

Whereon the stars in secret influence comment.

When I perceive that men as plants increase,

Cheered and checked even by the self-same sky:

Vaunt in their youthful sap, at height decrease,

And wear their brave state out of memory.

Then the conceit of this inconstant stay,

Sets you most rich in youth before my sight,

Where wasteful time debateth with decay

To change your day of youth to sullied night,

And all in war with Time for love of you,

As he takes from you, I engraft you new.

But wherefore do not you a mightier way

Make war upon this bloody tyrant Time?

And fortify your self in your decay

With means more blessed than my barren rhyme?

Now stand you on the top of happy hours,

And many maiden gardens yet unset,

With virtuous wish would bear you living flowers,

Much liker than your painted counterfeit:

So should the lines of life that life repair

Which this (Time's pencil) or my pupil pen

Neither in inward worth nor outward fair

Can make you live your self in eyes of men.

To give away your self, keeps your self still,

And you must live drawn by your own sweet skill.

Who will believe my verse in time to come

If it were filled with your most high deserts?

Though yet heaven knows it is but as a tomb

Which hides your life, and shows not half your parts: 

If I could write the beauty of your eyes,
