But the mother's new line of argument, to soothe her son's dangerous agitation, was fruitless as the other. His eyes flashed still more brilliantly with his burning indignation, as he retorted again: "You say right, my mother. The land of Aragon is so poor and barren, that perchance her sons and daughters might all long since have forsaken their churlish, niggard-handed mother, and finally renounced her, but that she gives them liberty. Even in our oath of allegiance we tender no slaves' submission to oppression." The widowed mother turned her sad eyes upon her proud-spirited boy. "My son, no oath of allegiance has as yet been called for from thy lips." The flush deepened on the young Spaniard's face. He pressed his teeth into the crimson lower lip for some seconds to strangle back a groan that sought escape from his own over-burdened heart. He had heard of the tragedies of those months before his birth. "No," he muttered at length bitterly. "No. It is true. I am esteemed too contemptible to have even vows wrung from me that are counted worthless. But the oath that my father spoke is registered in my heart; the oath due from us, whose proud heritage it is to call ourselves the nobles of Aragon. And such is the oath that I, in my turn, tender to my sovereign, Ferdinand of Aragon and Castile." The lad paused a moment, and then, with folded arms, and in low, firm tones, repeated the proud words of the Aragonese oath of allegiance. "We, who are each of us as good, and who are altogether more powerful than you, promise obedience to your government if you maintain our rights and liberties, but if not, not." As he spoke Rachel Diego dropped her face into her hands, and as he ended she murmured in stifled tones: "Your father pronounced that haughty vow, and what availed the boast?" What indeed! The young Montoro gazed for a moment at his wan mother, at the bare room, and then, with all his haughtiness lost in a flood of sudden despair, he darted from the miserable apartment to wrestle with his agitation in the wild darkness of a stormy night. That his heart should be torn with bitterness and grief was little wonder, for all too well he knew how it came to pass that his mother was fatherless and a widow, and how he himself had been robbed of his parent and his patrimony. Something of the dismal tale of Don Philip's tortured death, and of the base villain who had grasped at his daughter's fortune, had been told the boy from time to time by his mother. Something, also, of the avarice and barbarity that had wrested a few despairing words to the destruction of his own father, the noble Don Montoro de Diego.
