The most famous and the most important of these embassies was that which arrived in Constantinople in 449. The ambassadors then employed by Attila are worthy of notice, for in them we see not only the condition of things at that time, but also the naive cunning of the Hun. The two chief legates whom Attila dispatched to Constantinople upon this occasion were Edecon and Orestes. Edecon was a Scythian or Hun by birth, a heathen of course, and a Barbarian, the commander of the guard of Attila, and the father of Odoacer, later to be so famous. Orestes, on the other hand, who was one of Attila’s chief ministers, was a Roman provincial of Pannonia, born at Petavium (probably Pettau on the Drave), who had made a fortunate marriage as a young man when he allied himself with Romulus, a considerable Roman personage of that province. He had, however, deserted the Imperial service, certainly open to him, for that of the Barbarians, and had made his fortune. Nor was his part in history to be played out in the service of Attila, for his son Romulus was to be the last of the Western Emperors, contemptuously known to history as Romulus Augustulus. Orestes was then an adventurer pure and simple, but in sending him with the Barbarian Edecon, we see the system of Attila in his blackmail of the Empire. The employment of a Roman provincial was a check upon the Barbarian envoy. A bitter jealousy subsisted between them, each spied on the other, and thus Attila was well served. The fact that the Hun was able to command the services of such as Orestes is a sufficient comment upon the condition of the frontier provinces. It was these two jealous envoys that, in the early months of 449, appeared in Constantinople bringing, of course, new demands. Their mission, indeed, was the most insolent that Attila had so far dared to send. It demanded three main things; first, that all the country to the south of the Danube as far as Naissus should be regarded as a part of the Hunnish Empire; second, that in future Theodosius should send to the Hunnish court only the most illustrious ambassadors, but if this were done Attila for his part would consent to meet them on the frontier at Sardica; third, that the refugees should be delivered up. This last demand was a repetition of many that had gone before it. As before Attila threatened if his requests were not granted he would make war.
