Today, for the first time ever in my memory, because we had six or seven inches of snow, the United States Postal Service did not deliver the mail in my neighborhood in Lawrence, KS. I called them up to ask about their official creed: “Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.” And they said that the United States Postal Service has no such official creed or motto.
So I did some checking, and they’re right. Apparently, the quotation in question is merely an inscription on the James Farley Post Office in New York City; and this, in turn, is attributed to Herodotus, the Greek historian who, in his Histories, was referring admiringly to the courier service of the ancient Persian Empire.
Oh, that our pony express should be outfoxed by camels!
