] and this was due to no other cause (nor is any other reported) save that event which gave rise to the title in this very war,--an event which enabled the Romans to survive on this occasion and brought destruction upon the barbarians. It was not Arnouphis, the wizard, for Marcus is not accounted to have taken pleasure in the company of wizards and charms. But what I have reference to is as follows: Marcus had a company (and the Roman name for company is "legion") of soldiers from Melitene. They were all worshipers of Christ. Now it is stated that in that battle, when Marcus was in a quandary over having been surrounded and feared the loss of his whole army, the prefect approached him and said that those called Christians can accomplish anything whatever by their prayers, and that among them there chanced to be a whole company of this sect. Marcus, on hearing this, made an appeal to them to pray to their God. And when they had prayed, the God immediately gave ear, hurling a thunderbolt upon the enemy and encouraging the Romans with rain. Marcus was astounded at what happened and honored the Christians by an official decree, while the legion he named "The Thunderbolt." It is said also that there is a letter of Marcus extant on this matter. But the Greeks, though they know that the company was called "Thunderbolt" and bear witness to the fact themselves, make no statement whatever about the reason for the appellation.

Dio goes on to say that when the rain poured down at first all bent their faces upwards and received it in their mouths. Then some held their shields and their helmets as pails, and they themselves took fullmouthed draughts of it and gave their horses to drink. The barbarians making a charge upon them, they drank and fought at the same time; and some who were wounded gulped down together the water and the blood that flowed into their helmets. The most of them had given so much attention to drinking that they would have suffered some great damage from the enemy's onset had not a violent hail and numbers of thunderbolts fallen upon the latter's ranks. In the same spot one might see water and fire descending from Heaven at the same time: the one side was being drenched and drinking, the other was being burned with fire and dying. The fire did not touch the Romans, but if it fell anywhere among them it was straightway extinguished. On the other hand, the shower did the barbarians no good, but like oil served rather to feed the flames that fed on them, and they searched for water while in the midst of rain. Some wounded themselves in the attempt to put out the fire with blood, and others ran over to the side of the Romans, convinced that they alone had the saving water. Marcus finally took pity on them. He was for the seventh time saluted as imperator by the soldiers. And although he was not wont to accept any such honor before the senate voted it, [
] nevertheless this time he took it under the assumption that it was bestowed from Heaven, and he sent a despatch to that effect to the senate.--Moreover Faustina was named "Mother of the Legions."

[Marcus [Antoninus] remained in Pannonia in order to transact business with the embassies of the barbarians. Many came to him also at this time. Some promised an alliance: they were led by Battarius, a child twelve years old, and they received money and succeeded in restraining Tarbus, a neighboring potentate, who had come into Dacia, was demanding money, and threatening to make war if he should not get it. Others, like the Quadi, were asking for peace, and they obtained it, the emperor's purpose being to have them detached from the Marcomani. Another reason was that they gave horses and cattle, surrendered all the deserters and the captives at first to the number of thirteen thousand, though later they promised to restore the remainder as well. However, the right of free intercourse even at markets was not granted them, the intention being to prevent the Iazyges and the Marcomani, whom they had sworn not to receive nor let pass through their country, from either mingling with them or presenting themselves also in the guise of Quadi,--a plan which would enable them to reconnoitre the Roman position and to purchase provisions. Besides these who came to Marcus, many others despatched envoys, some by tribes and some by nations, offering to surrender themselves. Some of them were sent on campaigns to other parts of the world, and the captives and deserters who were fit for it were similarly treated. Others received land, in Dacia or in Pannonia or in Moesia and Germany or in Italy itself. A few of them who settled at Ravenna made an uprising and even dared to take possession of the city: and for this reason he did not again bring any barbarian into Italy, but made even those who had previously come there find homes outside.]
