Read 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 allow
for beauty's pattern to succeeding men.
yet, do thy worst old time: despite thy wrong,
my love shall in my verse ever live young.
