Xenophon quotes
Just as the various trades are most highly developed in large cities, in the same way food at the palace is prepared in a far superior manner. In small towns the same man makes couches, doors, plows and tables, and often he even builds houses, and still he is thankful if only he can find enough work to support himself. And it is impossible for a man of many trades to do all of them well. In large cities, however, because many make demands on each trade, one alone is enough to support a man, and often less than one: for instance one man makes shoes for men, another for women, there are places even where one man earns a living just by mending shoes, another by cutting them out, another just by sewing the uppers together, while there is another who performs none of these operations but assembles the parts, Of necessity, he who pursues a very specialised task will do it best.
Xenophon
The company, then, were feasting in silence, as though some one in authority had commanded them to do so, when Philip the buffoon knocked at the door and told the porter to announce who he was and that he desired to be admitted; he added that with regard to food he had come all prepared, in all varieties-to dine on some other person's,-and that his servant was in great distress with the load he carried of-nothing, and with having an empty stomach. Hearing this, Callias said, "Well, gentlemen, we cannot decently begrudge him at the least the shelter of our roof; so let him come in.” With the words he cast a glance at Autolycus, obviously trying to make out what he had thought of the pleasantry. But Philip, standing at the threshold of the men's hall where the banquet was served, announced: "You all know that I am a jester; and so I have come here with a will, thinking it more of a joke to come to your dinner uninvited than to come by invitation.”.
