OF THE EOMAN EMPIRE 63 concealed a dark and bloody design, and the credulous prince was persuaded to accept the pressing invitation of Marcellinus. I am at a loss how to vary the naiTative of similar crimes ; or how to relate that, in the course of the same year, but in remote parts of the empire, the inhospitable table of two Im- perial generals was stained with the royal blood of two guests and allies, inhumanly murdered by their order and in their presence. The fate of Gabinius and of Para was the same : but the cruel death of their sovereign was resented in a very different manner by the servile temper of the Armenians and the free and daring spirit of the Germans. The Quadi were much declined from that formidable power which, in the time of Marcus Antoninus, had spread terror to the gates of Rome. But they still possessed arms and courage ; their courage was animated by despair, and they obtained the usual reinforcement of the cavalry of their Sarmatian allies. So improvident was the assassin Marcellinus that he chose the moment when the bravest veterans had been drawn away to suppress the revolt of Firmus ; and the whole province was exposed, with a very feeble defence, to the rage of the exasperated Barbarians. They invaded Pannonia in the season of harvest ; unmercifully destroyed every object of plunder which they could not easily transport ; and either disregarded or demolished the empty fortifications.

That royal maid, who had innocently supported the revolt of Procopius, was now the destined wife of the heir of the Western empire. She traversed the peaceful province with a splendid and unarmed train. Her person was saved from danger, and the republic from disgrace, by the active zeal of Messalla, governor of the provinces. As soon as he was informed that the village, where she stopped only to dine, was almost encompassed by the Bar- barians, he hastily placed her in his own chariot, and drove full speed till he reached the gates of Sirmium, which were at the distance of six and twenty miles. Even Sirmium might not have been secure, if the Quadi and Sarmatians had diligently advanced during the general consternation of the magistrates and people. Their delay allowed Pi'obus, the Praetorian prsefect, sufficient time to recover his own spirits and to revive the courage of the citizens. He skilfully directed their strenuous efforts to repair and strengthen the decayed fortifications; and procured the seasonable and effectual
