ined to acclaim Otho as he was returning from
dinner on the night of the fourteenth. However, they hesitated: the
darkness spelt uncertainty, the troops were scattered all over the
town, and unanimity could scarcely be expected from drunken men. They
were not deterred by any affection for their country's honour, which
they were deliberately preparing to stain with its emperor's blood,
but they were afraid that, as Otho was unknown to the majority, some
one else might by mistake be offered to the Pannonian or German
legions and proclaimed emperor. Some evidence of the brewing plot
leaked out, but it was suppressed by the conspirators. Rumours even
reached Galba's ears, but Laco made light of them, being totally
ignorant of soldiers' characters, hostile to any suggestion, however
wise, that was not his own, and extremely obstinate with men who knew
more than he did.

On January 15, as Galba was sacrificing in front of the temple of 27
Apollo, the priest Umbricius declared the omens unfavourable: treason
was impending, and an enemy within the walls. Otho, who was standing
beside Galba, overheard and construed the omen as being from his own
point of view a good one, favourable to his plans. In a few moments
his freedman, Onomastus, announced that the architect and contractors
were waiting to see him. This had been agreed upon as the signal that
the troops were assembling and the conspiracy was ripe. On being asked
where he was going, Otho pretended that he was buying an old property,
but suspected its condition and so had to inspect it first. Thus,
leaning on his freedman's shoulder, he passed through Tiberius' house
into the Velabrum and thence to the Golden Milestone at the foot of
the Temple of Saturn.[55] There thirty-three soldiers of the Body
Guard saluted him as emperor. When he showed alarm at the smallness of
their number they put him hastily into a litter, and, drawing their
swords, hurried him away. About the same number of soldiers joined
them on the way, some accomplices, others merely curious. Some marched
along shouting and flourishing swords; others kept silent, intending
to take their cue from subsequent events.

Julius Martialis was the tribune on duty in the camp. He was so 28
overcome by the magnitude of this unexpected crime and so afraid that
the treason was widespread in the camp, and that he might be killed if
he offered any opposition, that he led most people to suppose he was
in the
