But as for Poppaea, Otho corrupted her with hopes of Nero’s favour and seduced her first himself, and persuaded her to leave her husband. However, after she had come to live with him as his wife, he was not content to have only a share in her favours, and was loth to give Nero a share, while Poppaea herself, as we are told, was not displeased at the rivalry between them.
For it is said that she would shut out Nero although Otho was not at home; whether it was that she sought to keep his pleasure in her from cloying, or whether, as some say, she recoiled from a marriage with the emperor, but was not averse to having him as a lover, out of mere wantonness. Otho, accordingly, came into peril of his life; and it was strange that although his own wife and sister were put to death by Nero on account of his marriage with Poppaea, Otho himself was spared.[*](Cf. Tacitus, Annals, xiii. 45 f. )
But Otho had the good will of Seneca, by whose advice and persuasion Nero sent him out as governor of Lusitania to the shores of the western ocean. Here he made himself acceptable and pleasing to his subjects, although he knew that his office had been given him to disguise and mitigate his banishment.
When Galba revolted, Otho was the first of the provincial governors to go over to him, and bringing all the gold and silver that he had in the shape of drinking-cups and tables, he gave it to him for conversion into coin, presenting him also with those of his servants who were qualified to give suitable service for the table of an emperor. In other ways he was trusted by Galba, and when put to the test was thought to be inferior to none as a man of affairs; and during the entire journey of the emperor he would travel in the same carriage with him for many days together.
