The north of Italy was also threatened by the rude people beyond the Alps, from the borders of Gallia to the eastern side of the Hadriatic. These barbarians attempted to break into Italy, as the Germanic nations had attempted near three hundred years before; and the rest of the life of Antoninus, with some intervals, was employed in driving back the invaders. In 169 Verus suddenly died, and Antoninus administered the state alone.
During the German wars Antoninus resided for three years on the Danube at Carnuntum. The Marcomanni were driven out of Pannonia and almost destroyed in their retreat across the Danube; and in A.D. 174 the emperor gained a great victory over the Quadi.
In A.D. 175, Avidius Cassius, a brave and skilful Roman commander who was at the head of the troops in Asia, revolted, and declared himself Augustus. But Cassius was assassinated by some of his officers, and so the rebellion came to an end. Antoninus showed his humanity by his treatment of the family and the partisans of Cassius; and his letter to the Senate, in which he recommends mercy, is extant. (Vulcatius, Avidius Cassius, c. 12.)
Antoninus set out for the East on hearing of Cassius' revolt. Though he appears to have returned to Rome in A.D. 174, he went back to prosecute the war against the Germans, and it is probable that he marched direct to the East from the German war. His wife Faustina, who accompanied him into Asia, died suddenly at the foot of the Taurus, to the great grief of her husband. Capitolinus, who has written the life of Antoninus, and also Dion Cassius, accuses the empress of scandalous infidelity to her husband, and of abominable lewdness. But Capitolinus says that Antoninus either knew it not or pretended not to know it. Nothing is so common as such malicious reports in all ages, and the history of imperial Rome is full of them. Antoninus loved his wife, and he says that she was "obedient, affectionate, and simple." The same scandal had been spread about Faustina's mother, the wife of Antoninus Pius, and yet he too was perfectly satisfied with his wife. Antoninus Pius says after her death, in a letter to Fronto, that he would rather have lived in exile with his wife than in his palace at Rome without her. There are not many men who would give their wives a better character than these two emperors. Capitolinus wrote in the time of Diocletian. He may have intended to tell the truth, but he is a poor, feeble biographer. Dion Cassius, the most malignant of historians, always reports, and perhaps he believed, any scandal against anybody.
Antoninus continued his journey to Syria and Egypt, and on his return to Italy through Athens he was initiated into the Eleusinian mysteries. It was the practice of the emperor to conform to the established rites of the age, and to perform religious ceremonies with due solemnity. We cannot conclude from this that he was a superstitious man, though we might perhaps do so if his book did not show that he was not. But that is only one among many instances that a ruler's public acts do not always prove his real opinions. A prudent governor will not roughly oppose even the superstitions of his people; and though he may wish they were wiser, he will know that he cannot make them so by offending their prejudices.
Antoninus and his son Commodus entered Rome in triumph, perhaps for some German victories, on the 23d. of December, A.D. 176. In the following year Commodus was associated with his father in the empire, and took the name of Augustus. This year A.D. 177 is memorable in ecclesiastical history. Attalus and others were put to death at Lyon for their adherence to the Christian religion. The evidence of this persecution is a letter preserved by Eusebius (E.H. V. I; printed in Routh's Reliquiae Sacrae, vol. i, with notes). The letter is from the Christians of Vienna and Lugdunum in Gallia (Vienna and Lyon) to their Christian brethren in Asia and Phrygia; and it is preserved perhaps nearly entire. It contains a very particular description of the tortures inflicted on the Christians in Gallia, and it states that while the persecution was going on, Attalus, a Christian and a Roman citizen, was loudly demanded by the populace and brought into the amphitheatre; but the governor ordered him to be reserved, with the rest who were in prison, until he had received instructions from the emperor. Many had been tortured before the governor thought of applying to Antoninus. The imperial rescript, says the letter, was that the Christians should be punished, but if they would deny their faith, they must be released. On this the work began again. The Christians who were Roman citizens were beheaded; the rest were exposed to the wild beasts in the amphitheatre. Some modern writers on ecclesiastical history, when they use this letter, say nothing of the wonderful stories of the martyrs' sufferings. Sanctus, as the letter says, was burnt with plates of hot iron till his body was one sore and had lost all human form; but on being put to the rack he recovered his former appearance under the torture, which was thus a cure instead of a punishment. He was afterwards torn by beasts, and placed on an iron chair and roasted. He died at last.
The letter is one piece of evidence. The writer, whoever he was that wrote in the name of the Gallic Christians, is our evidence both for the ordinary and the extraordinary circumstances of the story, and we cannot accept his evidence for one part and reject the other. We often receive small evidence as a proof of a thing we believe to be within the limits of probability or possibility, and we reject exactly the same evidence, when the thing to which it refers appears very improbable or impossible. But this is a false method of inquiry, though it is followed by some modern writers, who select what they like from a story and reject the rest of the evidence; or if they do not reject it, they dishonestly suppress it. A man can only act consistently by accepting all this letter or rejecting it all, and we cannot blame him for either. But he who rejects it may still admit that such a letter may be founded on real facts; and he would make this admission as the most probable way of accounting for the existence of the letter; but if, as he would suppose, the writer has stated some things falsely, he cannot tell what part of his story is worthy of credit.
The war on the northern frontier appears to have been uninterrupted during the visit of Antoninus to the East, and on his return the emperor again left Rome to oppose the barbarians. The Germanic people were defeated in a great battle A.D. 179. During this campaign the emperor was seized with some contagious malady, of which he died in the camp at Sirmium (Mitrovitz), on the Save, in Lower Pannonia, but at Vindebona (Vienna), according to other authorities, on the 17th of March, A.D. 180, in the fifty-ninth year of his age. His son Commodus was with him. The body, or the ashes probably, of the emperor were carried to Rome, and he received the honor of deification. Those who could afford it had his statue or bust; and when Capitolinus wrote, many people still had statues of Antoninus among the Dei Penates or household deities. He was in a manner made a saint. Commodus erected to the memory of his father the Antonine column which is now in the Piazza Colonna at Rome. The bassi rilievi which are placed in a spiral line round the shaft commemorate the victories of Antoninus over the Marcomanni and the Quadi, and the miraculous shower of rain which refreshed the Roman soldiers and discomfited their enemies. The statue of Antoninus was placed on the capital of the column, but it was removed at some time unknown, and a bronze statue of St. Paul was put in the place by Pope Sixtus the fifth.
The historical evidence for the times of Antoninus is very defective, and some of that which remains is not credible. The most curious is the story about the miracle which happened in A.D. 174, during the war with the Quadi. The Roman army was in danger of perishing by thirst, but a sudden storm drenched them with rain, while it discharged fire and hail on their enemies, and the Romans gained a great victory. All the authorities which speak of the battle speak also of the miracle. The Gentile writers assign it to their gods, and the Christians to the intercession of the Christian legion in the emperor's army. To confirm the Christian statement it is added that the emperor gave the title of Thundering to this legion; but Dacier and others, who maintain the Christian report of the miracle, admit that this title of Thundering or Lightning was not given to this legion because the Quadi were struck with lightning, but because there was a figure of lightning on their shields, and that this title of the legion existed in the time of Augustus. Scaliger also had observed that the legion was called Thundering (κεραυνοβόλος or κεραυνοφόρος) before the reign of Antoninus. We learn this from Dion Cassius (Lib. 55, c. 23, and the note of Reimarus), who enumerates all the legions of Augustus' time. The name Thundering of Lightning also occurs on an inscription of the reign of Trajan, which was found at Trieste. Eusebius (v. 5), when
