The voice in which these words were uttered rose like thunder above the _mêlée_, compelling even the two long lines of combatants to pause and turn their eyes towards the speaker. On the edge of the choir, and with hand uplifted, stood a stately figure clothed in a brilliant and imposing uniform, a figure half a head taller at least than the usual height of men, and standing as he did upon the elevated pavement of the choir, his stature seemed more than human. Though few in the cathedral had ever before seen this personage, yet all recognized in a moment the superb brow, the severe, haughty features, the dark eyes always melancholy, even when the mouth smiled. "The devil himself at last!" murmured Zabern, a grim joy stealing over his face. "Now have the saints delivered him as a hostage into our hands!" The stranger's form seemed really to dilate, as, with the voice of one born to command, he again cried,-- "Down with your arms!" Furious conspirators, advancing to slay, had once been awed and checked by that lofty voice, that majestic presence, which did not fail now to produce a remarkable effect. "The Czar! the Czar!" cried the Poles. "The little father! the little father!" cried the Muscovites. The fighting ceased. The assailants on each side fell back. Slowly the tumult died away in utter silence. The wounded repressed their groans; for wounded there were; many, too, brief as had been the combat; and one man lay dead upon the pavement, slain by the hand of a woman. The Czar, for it was in truth the mighty Nicholas, turned his face slowly round upon all sides. The fiercest of the Poles felt compelled to sheathe his blade and to resume his seat as that terrible eye fell upon him. Who durst continue to assail a Muscovite with the lord of the Muscovites looking on, even though that lord were without a single guard? It was somewhat mortifying to Barbara's pride that the cessation of the strife should have been caused by the authority of the Czar rather than by her own, since it seemed to place him upon a higher plane than herself. Clearly he had prevented a massacre of her Muscovite subjects, and thus far thanks were due to him. But Barbara was in no mood to offer courtesies to one who had always shown himself a bitter enemy. The very authority now assumed by him was an infringement of her own, and put her instantly upon her mettle. Among the combatants there was one at least who retained an undaunted mien, namely, Katina. She advanced towards the choir, wiping her reddened blade upon the silken standard, which during the fray had become detached from the staff. At the edge of the choir Katina knelt. "Seek not pardon of me," exclaimed the Czar loftily, mistaking her purpose. "You who commenced the fray, you who have slain one of my own subjects!"
