Incidents of this sort were, doubtless, of frequent occurrence and show what the Seleucids had to guard against. Their land policy seems to have been prudent and far-sighted. They were bound to deal cautiously with their gigantic domain, since from it came the most valuable and stable portion of their revenues. On the other hand, they found a limit set to the quantity which they could profitably retain by the fact that, unlike the Ptolemies, they inherited from the Persians a public service adequate, not to administer, but simply to supervise administration. They did indeed increase the number of their satrapies, without, perhaps, diminishing the number of chiliarchies or hyparchies into which each satrapy was divided, and they seem to have paralleled the general service by a distinct fiscal service and by a distinct priestly service; but, none the less, they had to leave the details of fiscal, judicial, and religious administration to the villages. Though we are singularly ill-informed as to how they organized the villages, it is conceivable that they picked out certain persons, like the elders in the Egyptian villages, and held them responsible for the taxes of the villagers and for their general good behavior. These men would be rather hostages than officials, and would be nominees of the central government rather than of the villages. But we really know nothing of the facts, except that the villagers had some means by which they paid their taxes collectively. One way by which the Seleucids could relieve themselves of the troubles of local administration and at the same time strengthen their hold upon the country was to make grants of whole blocks or complexes of their land, villages and villagers and all, to Macedonian and Greek feudatories, like Mnesimachus, who of course became responsible for the dues owing to the crown. But the evils of this system had been discovered by the Persian kings when they found their vassals more unruly than the villages. Hence the Seleucids refused to give a clear title to those to whom they made grants of portions of the royal domain, and in the case of Mnesimachus the temple of Artemis, to which he sold his rights, had to secure itself in the contract against the loss which it might sustain should the king recall his grant. On the other hand, when the king sold outright parts of the domain, as he frequently did, particularly in times of financial distress, and the lands and villages sold became with their peasants private property, he required that they should be added to the territory of some city-state, it being a privilege highly cherished by the purchasers that they should be given the liberty of deciding to which city their property should belong. The Seleucid policy that land should belong either to a city-state or to the crown was admirably calculated to destroy priestly and feudal sovereignties, and it was taken over by the Roman emperors,
