On that day, in the morning, Galba sacrificed in the Palatium in the presence of his friends, when Umbricius, the priest, taking up the entrails, and speaking not ambiguously, but in plain words, said that there were signs of great troubles ensuing, and dangerous snares laid for the life of the emperor. Thus Otho had even been discovered by the finger of the god; being there just behind Galba, bearing all that was said, and seeing what was pointed out to them by Umbricius. His countenance changed to every colour in his fear, and he was betraying no small discomposure, when Onomastus, his freedman, came up and acquainted him that the master builders had come, and were waiting for him at home. Now that was the signal for Otho to meet the soldiers. Pretending then that he had purchased an old house, and was going to show the defects to those that had sold it to him, he departed; and passing through what is called Tiberius's house, he went on into the forum, near the spot where a golden pillar stands, at which all the several roads through Italy terminate.
Here, it is related, no more than twenty-three received and saluted him emperor; so that, although he was not in mind as in body enervated with soft living and effeminacy, being in his nature bold and fearless enough in danger, nevertheless, he was afraid to go on.
But the soldiers that were present would not suffer him to recede, but came with their swords drawn around his chair, commanding the bearers to take him up, whom he hastened on, saying several times over to himself, "I am a lost man." Several persons overheard the words, who stood by wondering, rather than alarmed, because of the small number that attempted such an enterprise. But as they marched on through the forum, about as many more met him, and here and there three or four at a time joined in. Thus returning towards the camp, with their bare swords in their hands, they saluted him as Caesar;whereupon Martialis, the tribune in charge of the watch, who was, they say, noways privy to it, but was simply surprised at the unexpectedness of the thing, and afraid to refuse, permitted him entrance. And after this, no man made any resistance; for they that knew nothing of the design, being purposely encompassed by the conspirators, as they were straggling here and there, first submitted for fear, and afterwards were persuaded into compliance.
Tidings came immediately to Galba in the Palatium, whilst the priests were still present and the sacrifices at hand, so that persons who were most entirely incredulous about such things, and most positive in their neglect of them, were astonished, and began to marvel at the divine event. A multitude of all sorts of people now began to run together out of the forum; Vinius and Laco and some of Galba's freedmen drew their swords and placed themselves beside him;Piso went forth and addressed himself to the guards on duty in the court; and Marius Celsus, a brave man, was despatched to the Illyrian legion, stationed in what is called the Vipsanian chamber, to secure them.
Galba now consulting whether he should go out, Vinius dissuaded him, but Celsus and Laco encouraged him by all means to do so, and sharply reprimanded Vinius. But on a sudden a rumour came hot that Otho was slain in the camp; and presently appeared one Julius Atticus, a man of some distinction in the guards, running up with his drawn sword, crying out that he had slain Caesar's enemy; and pressing through the crowd that stood in his way, he presented himself before Galba with his bloody weapon, who, looking on him, demanded, "Who gave you your orders?" And on his answering that it had been his duty and the obligation of the oath he had taken the people applauded, giving loud acclamations, and Galba got into his chair and was carried out to sacrifice to Jupiter, and so to show himself publicly. But coming into the forum, there met him there, like a turn of wind, the opposite story, that Otho had made himself master of the camp. And as usual in a crowd of such a size, some called to him to return back, others to move forwards; some encouraged him to be bold and fear nothing, others bade him to be cautious and distrust. And thus whilst his chair was tossed to and fro, as it were on the waves, often tottering, there appeared first horse, and straightway heavy-armed foot coming through Paulus's court, and all with one accord crying out, "Down with this private man." Upon this, the crowd of people set off running, not to fly and disperse, but to possess themselves of the colonnades and elevated places of the forum, as it might be to get places to see a spectacle. And as soon as Atillius Vergilio knocked down one of Galba's statues, this was taken as the declaration of war, and they sent a discharge of darts upon Galba's litter, and missing their aim, came up and attacked him nearer hand with their naked swords.
No man resisted or offered to stand up in his defence, save one only, a centurion, Sempronius Densus, the single man among so many thousands that the sun beheld that day act worthily of the Roman empire, who, though he had never received any favour from Galba, yet out of bravery and allegiance endeavoured to defend the litter. First, lifting up his switch of vine, with which the centurions correct the soldiers when disorderly, he called aloud to the aggressors, charging them not to touch their emperor. And when they came upon him hand-to-hand, he drew his sword, and made a defence for a long time, until at last he was cut under the knees and brought to the ground.
