Shakespeare's Sonnet 14

Not from the stars do I my judgement pluck;And yet methinks I have astronomy,But not to tell of good or evil luck,Of plagues, of dearths, or seasons’ quality;Nor can I fortune to brief minutes tell,Pointing to each his thunder, rain and wind,Or say with princes if it shall go wellBy oft predict that I in heaven find:But from thine eyes my knowledge I derive,And constant stars in them I read such artAs ‘Truth and beauty shall together thrive,If from thyself, to store thou wouldst convert’;Or else of thee this I prognosticate:‘Thy end is truth’s and beauty’s doom and date.’

I do not draw my judgments from the stars, and yet I think I know something of astrology. But I cannot predict good or bad luck, plagues, famines, or what the seasons will be like. Nor can I tell anyone's fortune minute by minute, predicting their thunder, rain, and wind, or say whether princes will prosper from the predictions I often find in the heavens.
Instead, I draw my knowledge from your eyes. In those steady stars I read this lesson: truth and beauty will thrive together if you turn from living for yourself to having children. Otherwise, this is what I predict for you: your death will mark the final end of truth and beauty.
