Towards the evening he quenched his thirst with a draught of cold water. Two daggers were brought to him; he tried the edge of each, and then put one under his head. After satisfying himself that his friends had set out, he passed a tranquil night, and it is even said that he slept. At dawn he fell with his breast upon the steel. Hearing a groan from the dying man, his freedmen and slaves, and Plotius Firmus, prefect of the Praetorian Guard, came in. They found but one wound. His funeral was hastily performed. He had made this the subject of earnest entreaties, anxious that his head might not be cut off and subjected to indignities. The Praetorian cohorts carried his body with praises and tears, covering his wound and his hands with kisses. Some of the soldiers killed themselves near the funeral pile, not moved by remorse or by fear, but by the desire to emulate his glory, and by love of their prince. Afterwards this kind of death became a common practice among all ranks at Bedriacum, at Placentia, and in other camps. Over Otho was built a tomb unpretending and therefore likely to stand.
