On the 15th of January, as Galba was sacrificing in front of the temple of Apollo, the Haruspex Umbricius announced to him that the entrails had a sinister aspect, that treachery threatened him, that he had an enemy at home. Otho heard, for he had taken his place close by, and interpreted it by contraries in a favourable sense, as promising success to his designs. Not long after his freedman Onomastus informed him that the architect and the contractors were waiting for him. It had been arranged thus to indicate that the soldiers were assembling, and that the preparations of the conspiracy were complete. To those who inquired the reason of his departure, Otho pretended that he was purchasing certain farm-buildings, which from their age he suspected to be unsound, and which had therefore to be first surveyed. Leaning on his freedman's arm, he proceeded through the palace of Tiberius to the Velabrum, and thence to the golden milestone near the temple of Saturn. There three and twenty soldiers of the body-guard saluted him as Emperor, and, while he trembled at their scanty number, put him hastily into a chair, drew their swords, and hurried him onwards. About as many more soldiers joined them on their way, some because they were in the plot, many from mere surprise; some shouted and brandished their swords, others proceeded in silence, intending to let the issue determine their sentiments.
