Herodotus, while praising the democracy of Athens and the Greeks, testifies to the comparative purity of Persian lives, their honesty and heroism in war, the simplicity of their habits, to their industry and thrift in struggling with the natural obstacles of poor soil and difficult terrain and to their love of agricultural pursuits, etc.
Herodotus also praised the Persian postal network and, with that praise, was the originator of the motto of the U.S. Postal Service.
"Not snow, no, nor rain, nor heat, nor night keeps them from accomplishing their appointed courses with all speed. (Volume 4, Book 8, Chapter 98) ".
