Neither snow, nor rain, nor heat, nor gloom of night stays these couriers from the swift completion of their appointed rounds. [The Motto Of The U.S. Postal Service]
HerodotusAnd now for the vapor-bath: on a framework of three sticks, meeting at the top, they stretch pieces of woolen cloth, taking care to get the joints as perfect as they can, and inside this little tent they put a dish with red-hot stones in it. Then they take some hemp seed, creep into the tent, and throw the seed on to the hot stones. At once it begins to smoke, giving off a vapor unsurpassed by any vapor-bath one could find in Greece. The Sythians enjoy it so much that they howl with pleasure. This is their substitute for an ordinary bath in water, which they never use.
