XIII. On his expedition to meet the Cimbri, Marius continually exercised his forces in various ways in running and in forced marches; he also compelled every man to carry all his baggage and to prepare his own food, in consequence of which men who were fond of toil, and promptly and silently did what they were ordered, were called Marian mules. Some, however, think that this name had a different origin; as follows:--When Scipio was blockading Numantia, he wished to inspect not only the arms and the horses, but also the mules and waggons, in order to see in what kind of order and condition the soldiers kept them. Marius accordingly produced his horse, which he had kept in excellent condition with his own hand, and also a mule, which for good appearance, docility, and strength far surpassed all the rest. The general was much pleased with the beasts of Marius and often spoke about them, which gave rise to the scoffing epithet of Marian mule, when the subject of commendation was a persevering, enduring, and labour-loving man.
XIV. Marius was favoured by a singular piece of good fortune; for there was a reflux in the course of the barbarians, and the torrent flowed towards Iberia before it turned to Italy, which gave Marius time to discipline the bodies of his men and to confirm their courage; and what was most of all, it gave the soldiers an opportunity of knowing what kind of a man their general was. For the first impression created by his sternness and by his inexorable severity in punishing, was changed into an opinion of the justice and utility of his discipline when they had been trained to avoid all cause of offence and all breach of order; and the violence of his temper, the harshness of his voice, and ferocious expression of his countenance, when the soldiers became familiarised with them, appeared no longer formidable to them, but only terrific to their enemies. But his strict justice in all matters that came before him for judgment pleased the soldiers most of all; and of this the following instance is mentioned, Caius Lusius, who was a nephew of Marius, and was an officer in the army, was in other respects a man of no bad character, but fond of beautiful youths. This Caius conceived a passion for one of the young men who served under him, by name Trebonius, and had often ineffectually attempted to seduce him. At last Caius one night sent a servant with orders to bring Trebonius; the young man came, for he could not refuse to obey the summons, and was introduced into the tent; but when Caius attempted to use violence towards him, he drew his sword and killed him. Marius was not present when this happened, but on his arrival he brought Trebonius to trial. There were many to join in supporting the accusation, and not one to speak in his favour, but Trebouius boldly came forward and told the whole story; and he produced witnesses who proved that he had often resisted the importunities of Lusius, and that though great offers had been made, he had never prostituted himself; on which Marius, admiring his conduct, ordered a crown to be brought, such as was conferred for noble deeds according to an old Roman fashion, and he took it and put it on the head of Trebonius as a fit reward for so noble an act at a time when good examples were much needed. The news of this, reaching Rome, contributed in no small degree to the consulship being conferred on Marius for the third time; the barbarians also were expected about the spring of the year, and the Romans did not wish to try the issue of a battle with them under any other commander. However, the barbarians did not come so soon as they were expected, and the period of the consulship of Marius again expired. As the Comitia were at hand, and his colleague had died, Marius came to Rome, leaving Manius Aquilius in the command of the army. There were many candidates of great merit for the consulship, but Lucius Saturninus, one of the tribunes, who had most influence with the people, was gained over by Marius; and in his harangues he advised them to elect Marius consul. Marius indeed affected to decline the honour, and begged to be excused; he said he did not wish for it; on which Saturninus called him a traitor to his country for refusing the command at so critical a time. Now though it was apparent that Saturninus was playing a part at the bidding of Marius, and in such a way that nobody was deceived, still the many seeing that the circumstances required a man of his energy and good fortune, voted for the fourth consulship of Marius, and gave him for colleague Catulus Lutatius, a man who was esteemed by the nobility and not disliked by the people.
