"Of all the days in the year, the one which they celebrate most is their birthday. It is customary to have the board furnished on that day with an ampler supply than common. The richer Persians cause an ox, a horse, a camel, and an ass to be baked whole and so served up to them: the poorer classes use instead the smaller kinds of cattle. They eat little solid food but abundance of dessert, which is set on table a few dishes at a time; this it is which makes them say that "the Greeks, when they eat, leave off hungry, having nothing worth mention served up to them after the meats; whereas, if they had more put before them, they would not stop eating." They are very fond of wine, and drink it in large quantities. To vomit or obey natural calls in the presence of another is forbidden among them. Such are their customs in these matters. It is also their general practice to deliberate upon affairs of weight when they are drunk; and then on the morrow, when they are sober, the decision to which they came the night before is put before them by the master of the house in which it was made; and if it is then approved of, they act on it; if not, they set it aside. Sometimes, however, they are sober at their first deliberation, but in this case they always reconsider the matter under the influence of wine" (Source: Encyclopedia of Ancient Persia).
