Shakespeare's Sonnet 19

Devouring Time, blunt thou the lion’s paws,And make the earth devour her own sweet brood;Pluck the keen teeth from the fierce tiger’s jaws,And burn the long-liv’d phoenix, in her blood;Make glad and sorry seasons as thou fleets,And do whate’er thou wilt, swift-footed Time,To the wide world and all her fading sweets;But I forbid thee one most heinous crime:O! carve not with thy hours my love’s fair brow,Nor draw no lines there with thine antique pen;Him in thy course untainted do allowFor beauty’s pattern to succeeding men.Yet do thy worst, old Time; despite thy wrong,My love shall in my verse ever live young.

All-devouring Time, blunt the lion's claws and make the earth swallow her own beloved young. Pull the sharp teeth from the fierce tiger's jaws, and burn the long-lived phoenix alive. Bring happy and sorrowful seasons as you pass, and do whatever you want, swift-moving Time, to the wide world and all its fading beauties.
But I forbid you one terrible crime: do not carve wrinkles into my love's beautiful forehead with your passing hours, or draw lines there with your pen that makes things old. Let him pass through your course untouched, a model of beauty for future generations.
Still, do your worst, old Time. Despite the harm you do, my love will live forever young in my verse.
