But Glaucon met the Persian’s glance with one more bold.

“No, Mardonius, good friend, for do not think that we must be foes one to another because our people are at war,—I can answer you with ease. Leonidas you have slain, and his handful, and you have pierced the mountain wall of Œta, and no doubt your king’s host will march even to Athens. But do not dream Hellas is conquered by striding over her land. Before you shall possess the land you must first possess the men. And I say to you, Athens is still left, and Sparta left, free and strong, with men whose hearts and hands can never fail. I doubted once. But now I doubt no more. And our gods will fight for us. Your Ahura-Mazda has still to prevail over Zeus the Thunderer and Athena of the Pure Heart.”

“And you?” asked the Persian.

“And as for me, I know I have cast away by my own act all the good things you and your king would fain bestow upon me. Perhaps I deserve death at your hands. I will never plead for respite, but this I know, whether I live or die, it shall be as Glaucon of Athens who owns no king but Zeus, no loyalty save to the land that bore him.”

There was stillness in the tent. The wounded man sank back on the pillows, breathing deep, closing his eyes, expectant almost of a burst of wrath from the Persian. But Mardonius answered without trace of anger.

“Friend, your words cut keenly, and your boasts are high. Only the Most High knoweth whether you boast aright. Yet this I say, that much as I desire your friendship, would see you my brother, even,—you know that,—I dare not tell you you do wholly wrong. A man is given one country and one manner of faith in God. He does not choose them. I was born to serve the lord of the Aryans, and to spread the triumphs of Mithra the Glorious, and you were born in Athens. I would it were otherwise. Artazostra and I would fain have made you Persian like ourselves. My sister loves you. Yet we cannot strive against fate. Will you go back to your own people and share their lot, however direful?”

“Since life is given me, I will.”

Mardonius stepped to the bedside and gave the Athenian his right hand.

“At the island you saved my life and that of my best beloved. Let it never be said that Mardonius, son of Gobryas, is ungrateful. To-day, in some measure, I have repaid the debt I owe. If you will have it so, as speedily as your strength returns and opportunity offers I will return you to your people. And amongst them may your own gods show you favour, for you will have none from ours!”

Glaucon took the proffered hand in silent gratitude. He was still very weak and rested on the pillows, breathing hard. The bow-bearer went out to his wife and his sister and told his promise. There was little to be said. The Athenian must go his path, and they go theirs, unless he were to be handed over to Xerxes to die a death of torments. And not even Roxana, keenly as pierced her sorrow, would think of that.
