This constable felt death approaching and, being able to place little reliance on the good sense or courage of his sons, wrote to Anastasius, who had shown him many marks of favour, and offered to sell him the castle and the pass for a few thousand gold pieces. Anastasius called his principal Senators together and asked them for their opinion on the matter, which they gave as follows: 'The Caspian Gates would have been of great commercial importance to Your Sacred Majesty, had you been able to use the northern caravan-route for direct trade with China; but as this has been denied you by Persian intrigue there is no profit to be derived from them. Your Majesty will realize that the present constable, or his sons, will continue to hold the fortress without any inducement from you, merely to restrain raiders from the steppes from overrunning their own country. Moreover, to post a Roman garrison there would be both dangerous and expensive: for the Caspian Gates are situated two hundred miles beyond the eastern end of the Black Sea, and more than that distance from the Diocese of Pontus, which is the nearest of Your Clemency's personal dominions on the southern shores of that Sea: the Persian satrapy of Iberia lies between. We therefore advise Your Greatness to thank this Hun most courteously and to send him a worthy gift, but not to throw good money after bad; the Eastern frontier has already cost the Empire too dear.'
Anastasius unwisely took their advice. The constable died shortly afterwards, and the sons quarrelled over his will. Then the youngest of them, who was robbed of his inheritance, wrote to Kobad suggesting that a strong Persian force should seize the Gates, and that he himself should be appointed constable with a large yearly salary. Kobad sent the force, seized the Gates, killed all the sons, including the youngest one, and congratulated himself that his extreme Western dominions were now secure from attack by the Huns. If Anastasius had only had the courage to garrison the Gates, he could, whenever he pleased, have let loose swarms of raiders on the Persian part of Armenia, as easily as a gardener removes a stop from a garden reservoir and floods the irrigation channels.
So much for the Caspian Gates. As for Anastasius's fortification of Daras: it was forbidden by ancient treaty for either side to build any new fortifications on the frontier. The Persians greatly resented his action, but Anastasius further fortified the village of Erzeroum in Roman Armenia, and made a strong city of it. This, too, the Persians took very ill, and also his intriguing with the Manichcan monks in Persian Armenia, pretending to be a secret convert to their sect.
When Anastasius died, and Justin succeeded, Kobad grew anxious about the future. He knew Justin for a capable soldier and he felt his own death approaching. Like so many Eastern Kings, he hated his natural heir, whose name was Khaous. He doted on his youngest son Khosrou, the child of his second wife who by her self-sacrifice had once enabled him to escape from the so-called Castle of Oblivion, where he had been confined for two years by a usurper. She had changed clothes and places with him, and when the deception was discovered had been put to death by very cruel tortures. Kobad had sworn to her before he escaped that if ever he recovered his throne her son should be his successor. Besides Khaous, there was another son, Jamaspes, who was the most capable soldier in all Persia and had the confidence of the entire nobility; but he was not eligible for the throne because he had lost an eye in a battle with the Huns. No man with any deformity or mutilation is permitted to rule in Persia, and it is a peculiarity of Persian laws that they may never be cancelled or amended. Kobad pondered for years as to how he could set aside Khaous, who was loyally supported by his brother Jamaspes; but could hit on no answer to the problem. It was only when Anastasius died and Justin became Emperor that he decided on a course of action. He wrote Justin a strange letter, accompanying it with some very handsome presents of jewels and works of art. I quote it here with a few immaterial omissions.
'Kobad of the Sassanids, Brothcr of the Sun, Great King of the Persians, Acknowledged Emperor of Media, Iraq, Transjordania, Hither Arabia, Persarmenia, Kirman, Khorasan, Mckran, Oman, Sind, Sogdiana, and other lands too numerous conveniently to name in the course of this short letter, to Justin the Christian Emperor of the Romans, resident at Constantinople, sends greeting.
