“Rodrigo,” he whispers, and with an unutterable expression of despair he looks into his eyes, “are you brave?”

“Sir!” answers Rodrigo, drawing back his arm, “any other but you should feel it on the instant.”

“Oh, blessed anger!” replies Don Diego, watching the deep flush mounting on his face, “you are indeed my son. My blood flows in your veins. I was like that once. Prompt, ready, dexterous. Rodrigo, will you avenge me?”

I have told you vengeance is in your hand, for me, for you. Be worthy of your father, who was once a valiant knight. Go, I say,—rush—fly,—as though the earth burned under your footsteps! Nor let me behold you until you have washed out the stain!”
