"Do you understand?" went on Caesar, as calmly as though he had been expounding a problem of metaphysics. "You can take this ring of mine, and by its aid go through the whole legion, and obtain the best horses for flight, before anything is discovered. Your conscience need not trouble you. You will only have done as I earnestly requested." The cold sweat started to Drusus's forehead, his head swam; he knew that it was more than the mist of the river-fog that drifted before his eyes. Then, filled with a sudden impulse, he sprang on the general and wrenched the dagger from its sheath. "Here!" cried Caesar, tearing back the mantle from his breast. "There!" cried Drusus, and the bright blade glinted once in the air, and splashed down into the dark ripple. He caught the Imperator about the arms, and flung his head on the other's neck. "Oh! Imperator," he cried, "do not desert us. Do not desert the Commonwealth! Do not hand us back to new ruin, new tyrants, new wars! Strike, strike, and so be merciful! Surely the gods have not led you thus far, and no farther! But yesterday you said they were leading us. To-day they still must guide! To you it has been given to pull down and to build up. Fail not! If there be gods, trust in them! If there be none slay me first, then do whatever you will!" Caesar shook himself. His voice was harsh with command. "Unhand me! I must accomplish my own fate!" and then, in a totally different tone, "Quintus Drusus, I have been a coward for the first time in my life. Are you ashamed of your general?" "I never admired you more, Imperator." "Thank you. And will you go aside a little, please? I will need a few moments for meditation." Drusus hesitated. His eyes wandered off to the river. In one spot it was quite deep. "_Phui!_" said the proconsul, carelessly, "I am too brave for such a venture now. Leave me on my embankment, like Diogenes and his tub."
