The allurements of plenty engaged them to seek a permanent establishment on the frontiers of the empire.

Soon after the reign of Augustus, they obliged the Dacians, who subsisted by fishing on the banks of the River Teyss or Tibiscus, to retire into the hilly country, and to abandon to the victorious Sarmatians the fertile plains of the Upper Hungary, which are bounded by the course of the Danube and the semicircular enclosure of the Carpathian Mountains.

In this advantageous position, they watched or suspended the moment of attack, as they were provoked by injuries or appeased by presents; they gradually acquired the skill of using more dangerous weapons, and although the Sarmatians did not illustrate their name by any memorable exploits, they occasionally assisted their eastern and western neighbors, the Goths and the Germans, with a formidable body of cavalry.
They lived under the irregular aristocracy of their chieftains: but after they had received into their bosom the fugitive Vandals, who yielded to the pressure of the Gothic power, they seem to have chosen a king from that nation, and from the illustrious race of the Astingi, who had formerly dwelt on the shores of the northern ocean.
This motive of enmity must have inflamed the subjects of contention, which perpetually arise on the confines of warlike and independent nations.

The Vandal princes were stimulated by fear and revenge; the Gothic kings aspired to extend their dominion from the Euxine to the frontiers of Germany; and the waters of the Maros, a small river which falls into the Teyss, were stained with the blood of the contending Barbarians.

After some experience of the superior strength and numbers of their adversaries, the Sarmatians implored the protection of the Roman monarch, who beheld with pleasure the discord of the nations, but who was justly alarmed by the progress of the Gothic arms.
