The Roman History of Ammianus Marcellinus

filled with mourning for these executions which were perpetrated either by Maximin himself when he was present in the city, or by his emissaries when he was at a distance.

57. But the avenging Furies of those who had been murdered were preparing retribution. For, as I will afterwards relate at the proper season, this same Maximin giving way to his intolerable pride when Gratian was emperor, was put to death by the sword of the executioner; and Simplicius also was beheaded in Illyricum. Doryphorianus too was condemned to death, and thrown into the Tullian prison, but was taken from thence by the emperor at his mother's suggestion, and when he was brought back to his own country was put to death with terrible torments. Let us now return to the point at which we left our history. Such, however, was the state of affairs in the city of Rome.

II.

A.D. 369.

§ 1. Valentinian having several great and useful projects in his head, began to fortify the entire banks of the Rhine, from its beginning in the Tyrol to the straits of the ocean,[166] with vast works; raising lofty castles and fortresses, and a perfect range of towers in every suitable place, so as to protect the whole frontier of Gaul; and sometimes, by constructing works on the other side of the river, he almost trenched upon the territories of the enemy.

2. At last considering that one fortress, of which he himself had laid the very foundations, though sufficiently high and safe, yet, being built on the very edge of the river Neckar, was liable to be gradually undermined by the violent beating of its waters, he formed a plan to divert the river itself into another channel; and, having sought out some workmen who were skilful in such works and collected a strong military force, he began that arduous labour.

3. Day after day large masses of oaken beams were fastened together, and thrown into the channel, and by them huge piles were continually fixed and unfixed, being all thrown into disorder by the rising of the stream, and afterwards they were broken and carried away by the current.

4. However, the resolute diligence of the emperor and the labour of the obedient soldiery prevailed; though the troops were often up to their chins in the water while at work; and at last, though not without considerable risk, the fixed camp was protected against all danger from the violence of the current, and is still safe and strong.

5. Joyful and exulting in this success, the emperor, perceiving that the weather and the season of the year did not allow him any other occupation, like a good and active prince began to apply his attention to the general affairs of the republic. And thinking the time very proper for completing one work which he had been meditating, he began with all speed to raise a fortification on the other side of the Rhine, on Mount Piri, a spot which belongs to the barbarians. And as rapidity of action was one great means of executing this design with safety, he sent orders to the Duke Arator, through Syagrius, who was then a secretary, but who afterwards became prefect and consul, to attempt to make himself master of this height in the dead of the night.

6. The duke at once crossed over with the secretary, as he was commanded; and was beginning to employ the soldiers whom he had brought with him to dig out the foundations, when he received a successor, Hermogenes. At the very same moment there arrived some nobles of the Allemanni, fathers of the hostages, whom, in accordance with our treaty, we were detaining as important pledges for the long continuance of the peace.
