All sorts of views were examined, and finally the Lord Chancellor, as an expert on law, gave it as his mature opinion that Kobad was hiding extreme cunning under the guise of extreme simplicity: he intended to have Khosrou adopted as Justin's son so that he could legally claim the Empire when Justin died. Any ordinary person – but no ordinary person was present – would have realized at once the absurdity of this argument. In the first place, the Persians are a truthful people, and the Great King would not be capable of lowering his royal dignity by such a pettifogging trick; in the second, no Persian had the least prospect of being accepted by us as a candidate for the Roman Throne, not oven if he allowed himself to be baptized a Christian, which would, of course, cut him off from communion with his fellow fire-worshippers. The fact was, that Kobad was making a sincere and neighbourly offer (light-house signalling to light-house), just as Arcadius had once done. But the Lord Chancellor's view frightened Justinian, who wished to have no rivals to the succession; and even Theodora, who judged the letter to be what it purported to be, could not persuade him to return to a sensible view of the matter. So Justin was obliged to return an inept answer to Kobad, in which he offered to adopt Khosrou by the ceremony of arms, but not by Imperial charter. The former method of adoption is used chiefly among the Goths. The prospective father presents a horse and a complete suit of armour to the prospective son and utters the simple formula:' You are my excellent Son. This day, after the custom of the Nations and in manly fashion, I have begotten you. Let my foes be your foes; my friends, your friends; my kin, your kin.' The difference between this formula and civil adoption, by charter, is that it is not recognized by Roman Law as conferring on the son any title to the patrimony, but only as a contract of legal protection on the one hand and filial obedience on the other.
Before calling the Council, Justinian had privately assured the Persian ambassador that the Emperor would, he thought, accept the charge with alacrity; and the ambassador had thereupon sent a message to Khosrou to be ready at the frontier, whence he would shortly be escorted to Constantinople for the adoption ceremony. But now, of course, things were altered. Khosrou felt bitterly insulted at the shabby reply which a Roman ambassador brought to his representative at Nisibis on the frontier. A simple 'no' would have been far less galling than a 'no' masquerading as a 'yes'. Did Justin really expect that the ruler of the oldest and greatest kingdom in the civilized world would allow his favourite son, his chosen successor, a prince with the blood of Artaxerxes and Cyrus in his veins, to be treated like a barbarian German man-at-arms? War broke out soon afterwards; and in it Belisarius was given his first important command.
