It is said that as many days as there are in the whole journey, so many are the men and horses that stand along the road, each horse and man at the interval of a days journey; and these are stayed neither by snow nor rain nor heat nor darkness from accomplishing their appointed course with all speed.
HerodotusIf an important decision is to be made, they [the Persians] discuss the question when they are drunk, and the following day the master of the house where the discussion was held submits their decision for reconsideration when they are sober. If they still approve it, it is adopted; if not, it is abandoned. Conversely, any decision they make when they are sober, is reconsidered afterwards when they are drunk.
