Refrigerator magnet pictures a 1910 rural mail delivery on snowy wintertime lane with a phrase frequently, but inaccurately, described as the USPS creed: "Neither snow, nor rain, nor heat, nor gloom of night, stays these couriers from the swift completion of their appointed rounds." USPS does not have an official motto or creed and this much remembered phrase was actually popularized after being inscribed on the granite wall of the post office at 33rd Street and 8th Avenue in New York City. It is a modified translation of a remark used in an ancient Greece book, The Persian Wars by Herodotus, to describe postal workers in 503 BC. Constructed in 1914, the NYC post office architects included William Mitchell Kendal, son of a classics scholar, who got the phrase from his father, who in turn got the original translation from a Harvard professor, George Herbert Palmer. That it has "stuck" for a century, without any official designation, is testimony to the admiration America has for its postal workers.
