The Marisus River flows through their country into the Danuvius,1
on which the Romans used to convey their equipment for war; the “Danuvius” I say, for so they used to call the upper part of the river from near its sources on to the cataracts, I mean the part which in the main flows through the country, of the Daci, although they give the name “Ister” to the lower part, from the cataracts on to the Pontus, the part which flows past the country of the Getae. The language of the Daci is the same as that of the Getae. Among the Greeks, however, the Getae are better known because the migrations they make to either side of the Ister are continuous, and because they are intermingled with the Thracians and Mysians. And also the tribe of the Triballi, likewise Thracian, has had this same experience, for it has admitted migrations into this country, because the neighboring peoples force them2
to emigrate into the country of those who are weaker; that is, the Scythians and Bastarnians and Sauromatians on the far side of the river often prevail to the extent that they actually cross over to attack those whom they have already driven out, and some of them remain there, either in the islands or in Thrace, whereas those3
on the other side are generally overpowered by the Illyrians. Be that as it may, although the Getae and Daci once attained to very great power, so that they actually could send forth an expedition of two hundred thousand men, they now find themselves reduced to as few as forty thousand, and they have come close to the point of yielding obedience to the Romans, though as yet they are not absolutely submissive, because of the hopes which they base on the Germans, who are enemies to the Romans.
