The death of Rugilas suspended the progress of the treaty. His two nephews, Attila and Bleda, who succeeded to the throne of their uncle, consented to a personal interview with the ambassadors of Constantinople; but as they proudly refused to dismount, the business was transacted on horseback, in a spacious plain near the city of Margus, in the Upper Mæsia. The kings of the Huns assumed the solid benefits, as well as the vain honors, of the negotiation. They dictated the conditions of peace, and each condition was an insult on the majesty of the empire. Besides the freedom of a safe and plentiful market on the banks of the Danube, they required that the annual contribution should be augmented from three hundred and fifty to seven hundred pounds of gold; that a fine or ransom of eight pieces of gold should be paid for every Roman captive who had escaped from his Barbarian master; that the emperor should renounce all treaties and engagements with the enemies of the Huns; and that all the fugitives who had taken refuge in the court or provinces of Theodosius, should be delivered to the justice of their offended sovereign. This justice was rigorously inflicted on some unfortunate youths of a royal race. They were crucified on the territories of the empire, by the command of Attila: and as soon as the king of the Huns had impressed the Romans with the terror of his name, he indulged them in a short and arbitrary respite, whilst he subdued the rebellious or independent nations of Scythia and Germany.
