As Augustus meanwhile was taking his winter rest at Sirmium, frequent serious reports showed that the Sarmatians and the Quadi, who were in agreement because they were neighbours and had like customs and armour, had united and were raiding the Pannonias[*](That is, First and Second (Lower) Pannonia; the province was divided by Galerius.) and Second Moesia in detached bands.
These people, better fitted for brigandage than for open warfare, have very long spears and cuirasses made from smooth and polished pieces of horn, fastened like scales to linen shirts;[*](Pausanias, i. 21, 6, says that the Sarmatians made such armour from horses’ hoofs, having no iron, and that in the temple of Aesculapius at Athens, he saw a specimen, in which pieces of horn looked like clefts on a pine-cone.) most of their horses are made serviceable by gelding, in order that they may not at sight of mares become excited and run away, or when in ambush become unruly and betray their riders by loud neighing.
And they run over very great distances, pursuing others or themselves turning their backs,
And so, when the spring equinox was past, the emperor mustered a strong force of soldiers and set out under the guidance of a more propitious fortune; and although the river Ister was in flood since the masses of snow and ice were now melted, having come to the most suitable place, he crossed it on a bridge built over the decks of ships and invaded the savages’ lands with intent to lay them waste. They were outwitted by his rapid march, and on seeing already at their throats the troops of a fighting army, which they supposed could not yet be assembled owing to the time of year, they ventured neither to take breath nor make a stand, but to avoid unlooked-for destruction all took to precipitate flight.
The greater number, since fear clogged their steps, were cut down; if speed saved any from death, they hid in the obscure mountain gorges and saw their country perishing by the sword; and they might undoubtedly have protected her, had they resisted with the same vigour that had marked their flight.
