The Pillar of Fame
BY ROBERT HERRICK
Fame’s pillar here at last we set,
Out-during marble, brass or jet;
Charmed and enchanted so
As to withstand the blow
O f o v e r t h r o w ;
Nor shall the seas,
Or o u t r a g e s
Of storms, o’erbear
What we uprear;
Tho’ kingdoms fall,
This pillar never shall
Decline or waste at all;
But stand for ever by his own
Firm and well-fixed foundation.
