Weapons and Helmet of the Gauls
Had the Roman Empire been in the condition in which it was left by Augustus, Valerian might have emulated that emperor, and have displayed his virtues and beneficence in promoting the happiness of his subjects. But a great change had taken place in the condition of Rome; her legions no longer inspired their ancient terror; her northern and eastern provinces were exposed to the ravages of those who had formerly cowered before her eagles. Valerian could therefore only exhibit his wisdom in the selection of his generals; and it is to be observed that his choice never fell on an unworthy subject.
The enemies by whom the empire was assailed at this period were the Franks, the Alamanni, the Goths, and the Persians. As the scanty notices of these times do not enable us to arrange events chronologically, we will give a separate view of the wars with each of these peoples during the reigns of Valerian and his son.
[256-262 A.D.]
We have already observed the proneness of the Germanic tribes to form confederations. The Chauci, Cherusci, Chatti, and some adjoining states, had lately, it would seem, entered into one of these political unions under the name of Franks—i.e., freemen. Their strength and number now causing uneasiness for Gaul, the young emperor Gallienus was sent to that country; but the chief military command was conferred on Postumus, a man of considerable ability. The arms of the legions were successful in various encounters; but they were finally unable to prevent the passage of an army of the Franks through Gaul, whence surmounting the barrier of the Pyrenees they poured down into the now unwarlike Spain. The rich city of Tarraco was taken and sacked; the whole country was devastated, and the Franks, then seizing the vessels which they found in the ports, embarked to ravage Africa. We know not what was their ultimate fate; they were probably, however, destroyed in detail by the Roman troops and the provincials.
A portion of the great Suevian confederation had formed a new combination under the name of Alamanni—i.e., all men, on account of the variety of tribes which composed it. Like the Suevi, their forces were chiefly composed of cavalry, with active footmen mingled with them; and they always proved a formidable foe. While Gallienus was in Gaul a body of them entered Italy, penetrated as far as Ravenna, and their advanced troops came nearly within sight of Rome. The senate drew out the prætorian guards, and added to them a portion of the populace to oppose them; and the barbarians, finding themselves greatly outnumbered, hastened to get beyond the Danube with their plunder. Gallienus it is said was so much alarmed at the spirit and energy shown by the senate on this occasion, that he issued an edict interdicting all military employments to the senators, and even prohibiting their access to the camps of the legions. It is added that the luxurious nobles viewed this indignity as a favour rather than an insult.
Gallienus is also said to have overcome a large army of Alamanni in the vicinity of Mediolanum.[47] He afterwards espoused Pipa, daughter of the king of the Marcomanni (one of the confederates), to whom he gave a territory in Pannonia, as a means of averting the hostilities of the barbarians.
The Goths were now masters of the northern coast of the Euxine, and finding their attacks on the northern provinces generally repelled with vigour, they resolved to direct their efforts against more unwarlike districts. Collecting a quantity of the vessels used for navigating the Euxine, they embarked (258) and crossed that sea. They made their first attempt on the frontier town of Pityus, which was long ably defended against them; but they at length succeeded in reducing it. They thence sailed to the wealthy city of Trapezus (Trebizond); and though it was defended by a numerous garrison, they effected an entrance during the night. The cowardly garrison fled without making any resistance; the inhabitants were massacred in great numbers; the booty and number of captives were immense, and the victors having ravaged the province of Pontus embarked there on board of the ships which they found in the harbours, and returned to their settlement in the Tauric Chersonesus.
The next expedition of the Goths was directed to the Bosporus (261). They took and plundered Chalcedon and Nicomedia, Nicæa, Apamea, Prusa, and other cities of Bithynia. The accidental swelling of the little river Rhyndacus saved the town of Cyzicus from pillage.
The third expedition of the Goths was on a larger scale (262). Their fleet consisted of five hundred vessels of all sizes. They sailed along the Bosporus and Propontis; took and plundered Cyzicus; passed the Hellespont, and entered the Ægean. They directed their course to the Piræus; Athens could offer no resistance; the Goths ravaged Greece with impunity, and advanced to the shores of the Adriatic. Gallienus roused himself from his pleasures and appeared in arms. A Herulian chief with his men was induced to enter the Roman service; the Goths, weakened by this defection, broke up; a part forced their way to the Danube overland; the rest embarked and, pillaging and burning the temple of Diana at Ephesus on their way, returned to the Euxine.
