The Scythian hordes, which, towards the east, bordered on the new settlements of the Goths, presented nothing to their arms, except the doubtful chance of an unprofitable victory. But the prospect of the Roman territories was far more alluring; and the fields of Dacia were covered with rich harvests, sown by the hands of an industrious, and exposed to be gathered by those of a warlike, people. It is probable that the conquests of Trajan, maintained by his successors, less for any real advantage than for ideal dignity, had contributed to weaken the empire on that side. The new and unsettled province of Dacia was neither strong enough to resist, nor rich enough to satiate, the rapaciousness of the barbarians. As long as the remote banks of the Niester were considered as the boundary of the Roman power, the fortifications of the Lower Danube were more carelessly guarded, and the inhabitants of Mæsia lived in supine security, fondly conceiving themselves at an inaccessible distance from any barbarian invaders. The irruptions of the Goths, under the reign of Philip, fatally convinced them of their mistake. The king, or leader, of that fierce nation, traversed with contempt the province of Dacia, and passed both the Niester and the Danube without encountering any opposition capable of retarding his progress. The relaxed discipline of the Roman troops betrayed the most important posts, where they were stationed, and the fear of deserved punishment induced great numbers of them to enlist under the Gothic standard. The various multitude of barbarians appeared, at length, under the walls of Marcianopolis, a city built by Trajan in honor of his sister, and at that time the capital of the second Mæsia. The inhabitants consented to ransom their lives and property by the payment of a large sum of money, and the invaders retreated back into their deserts, animated, rather than satisfied, with the first success of their arms against an opulent but feeble country. Intelligence was soon transmitted to the emperor Decius, that Cniva, king of the Goths, had passed the Danube a second time, with more considerable forces; that his numerous detachments scattered devastation over the province of Mæsia, whilst the main body of the army, consisting of seventy thousand Germans and Sarmatians, a force equal to the most daring achievements, required the presence of the Roman monarch, and the exertion of his military power.
