Herotodus (c. 484 BC–c. 425 BC), on how the Persians reached decisions:
As regards their deliberations, all important decisions are first discussed when they are drunk. On the next day, the master of the house where they have assembled submits the decisions for reconsideration when they are sober. If it is approved, it is ratified; if not, it is abandoned. Conversely, any decision they have reached when they are sober is reconsidered when they are drunk.
