In the next place, if on the side of both parents, which means _Hasab va Nasab_, “accomplishments and genealogy,” he were of royal descent, it would be more advantageous: the meaning of royal birth is to be the possessor of the kingdom of justice; if every external qualification be united with the supreme power, it is much more agreeable, so that the king should not say, “I am more excellent than my father, and he than his ancestors:” on the contrary, he styles his father “highly distinguished,” and his grandfather “far superior.” Moreover, if any one should praise him on this account, he should order that person to be chastised. _Azizi_, “a distinguished man,”[356] has said: “The following is what we mean by this principle; that as one sire is superior to another, if a son should imagine himself the greater, then each child would reckon himself superior to his father, and there would then be no acknowledged ruler.” A king must also be provided with a distinguished mathematician as prime minister, to whom the calculators and astronomers should be subject; in every city there should be an astronomer or surveyor; and an _Arshiya_,[357] or accountant, should act as vizir, one well versed in the amount of rents paid by the Rayas; he must also have commissaries; and as there are attached to every city many villages and hamlets, the king’s private property, to which the local director attends, that officer is called the _Vizhak_. Also with every vizir, whether absent or present, there should be two _Ustuwars_ or supervisors, and two _Shudahbands_, or recorders of occurrences; the same rule is to be observed with all administrators, and the _Samán Sálár_, or head steward, the chief reporters and inspectors should also be each accompanied by two Ustuwars and two Shudahbands. _Dustoor_, or prime minister, means the person to whose department the public revenue is attached: the copies of the registers of all the vizirs should be regularly kept at the seat of government, as well as the papers of the Shudahbands.
