Henry Wadsworth Longfellow said this quote
“ Sadly as some old mediaeval knightGazed at the arms he could no longer wield,The sword two-handed and the shining shieldSuspended in the hall, and full in sight,While secret longings for the lost delightOf tourney or adventure in the fieldCame over him, and tears but half concealedTrembled and fell upon his beard of white,So I behold these books upon their shelf,My ornaments and arms of other days;Not wholly useless, though no longer used,For they remind me of my other self,Younger and stronger, and the pleasant waysIn which I walked, now clouded and confused. ”
