"'TIS THUS WHEN THE LOVELY SUMMER SUN

 OF OUR BOYHOOD, HIS COURSE HATH RUN:

 FOR ALL WE LIVE TO KNOW - IS KNOWN;

 AND ALL WE SEEK TO KEEP - HATH FLOWN;

 WITH THE NOON-DAY BEAUTY, WHICH IS ALL.

LET LIFE, THEN, AS THE DAY-FLOW'R FALL -

 THE TRANSIENT, PASSIONATE DAY-FLOW'R

 WITHERING AT THE EV'NING HOUR."

 - EDGAR ALLAN POE, 'TAMERLANE' VERSE XVI (1827)
