a disturbed kingdom. Roman invasions made apparently little mark, or perhaps are regarded by our historians as part of the course of nature, like an occasional flood; and are therefore received as sign-posts by which to date a chronicle, rather than as causes for astonishment or complaint. Less regular invasions, however, are noted. Thus, during the second century, the descent of hordes of robbers "from the mountains of Kardu"[1] is recorded, as if to show us that the Kurd of the period was still the turbulent fellow that Xenophon found him to be, and that he is to-day. A royal army had to be sent to put a stop to the inroad; and it was the good service rendered during the campaign by the Christian, Agha Raqbokt, that rendered it impossible for the Magians to proceed against him at the moment. It was his local knowledge that enabled the royalist general to extricate his army with credit from an awkward situation. Possibly the Magi might not have forgotten their quarrel, but the Agha was killed in action before the conclusion of the campaign.

The rebellion was put down by Valges IV, not without difficulty; and Narses, King of Adiabene, who was apparently a Persian sympathizer, paid the penalty of his treason by being drowned in the Zab. His country was plundered as punishment for the crime of its king, and all creeds suffered alike.
These, however, are but the ordinary troubles of an oriental kingdom; and on the whole it will be seen that under the Arsacids Christianity had a fair field, and came as near to complete toleration as was possible at the time. Hence it spread rapidly;
