Galba (19.3-19.4)

For because of Otho’s lavish prodigality Nero made an intimate friend of him, and was well pleased to be rallied by him often for parsimony and meanness. Thus, we are told that Nero once anointed himself with a costly ointment and sprinkled a little of it upon Otho; whereupon Otho, entertaining the emperor in his turn on the following day, suddenly brought into play gold and silver pipes on all sides of the room, out of which the ointment gushed freely, like so much water.

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.
