An elaborate Court ceremonial was the natural accompaniment of the ideas with respect to royalty embodied in the Persian system. Excepting the “Seven Princes,” no one could approach the royal person unless introduced by a Court usher, Prostration--the attitude of worship--was required of all as they entered the presence. The hands of the persons introduced had to be hidden in their sleeves so long as their audience lasted. In crossing the Palace Courts it was necessary to abstain carefully from touching the carpet which was laid for the king to walk on. Coming into the king’s presence unsummoned was a capital crime, punished by the attendants with instant death, unless the monarch himself, as a sign that he pardoned the intrusion, held out towards the culprit the golden sceptre which he bore in his hands. It was also a capital offence to sit down, even unknowingly, upon the royal throne; and it was a grave misdemeanor to wear one of the king’s cast-off dresses. Etiquette was almost as severe on the monarch himself as on his subjects. He was required to live chiefly in seclusion; to eat his meals, for the most part, alone; never to go on foot beyond the palace walls; never to revoke an order once given, however much he might regret it; never to draw back from a promise, whatever ill results he might anticipate from its performance. To maintain the quasi-divine character which attached to him it was necessary that he should seem infallible, immutable, and wholly free from the weakness of repentance. As some compensation for the restrictions laid upon him, the Persian king had the sole enjoyment of certain luxuries. The wheat of Assos was sent to the Court to furnish him with bread, and the vines of Helbon were cultivated for the special purpose of supplying him with wine. Water was conveyed to Susa for his use from distant streams regarded as specially sweet and pure; and in his expeditions he was accompanied, by a train of wagons, which were laden with silver flasks, filled from the clear stream of the Choaspes. The oasis of Ammon contributed the salt with which he seasoned his food. All the delicacies that the Empire anywhere produced were accumulated on his board, for the supply of which each province was proud to send its best and choicest products.
