Comment on The Belmont Club,"Waiting for D-Day"

There must be a short story or a poem by Cavafy in which the protagonist goes to visit a country house or a nations capital, some seat of ancient power. He runs in his mind over the giants that have walked the corridors, their dignity and courage and learning and sacrifice. He hopes that he will be found worthy to join their company in any capacity, no matter how small. Upon arrival he enters and admires the gleaming columns, the echoing chambers and the carved quotations of wisdom but all seems empty. Eventually he pushes open a huge bronze door and finds, the likes of Olberman and Franks and Obama.
