Suddenly the joy-bells began to ring, and the little people came laughing and singing and shouting from the steep streets and staircases and alleys, and they raced and danced into the piazza like Springtime let loose, and they chased each other, and caught hands and played in rings, and swarmed among the jars, as many and noisy as swallows when they gather for their flight over sea in the autumn-tide. "Look well, Messer Gianni," said the Frate, "and perceive who it is that shares their frolics." As the Brother spoke the eyes of the Syndic were opened; and there, with each little child, was his Angel, clothed in white, and white-winged; and as the little folk contended together, their Angels contended with each other; and as they ran and danced and sang, so ran and danced and sang their Angels. Which was the laughter of the children, and which that of the Angels, the Syndic could not tell; and when the plump two-year-olds tottered and tumbled, their Angels caught them and saved them from hurt; and even if they did weep and make a great outcry, it was because they were frightened, not because they were injured, and straightway they had forgotten what ailed them and were again merrily trudging about. In the midst of this wonderful vision of young Angels and bright-eyed children mingling so riotously together, the Syndic heard an inexpressibly joyous laugh behind him. Turning his head, he saw that it was the little marble Babe in the arms of the Madonna. He was clapping his hands, and had thrown back his head against his mother's bosom in sudden delight. Did the Syndic truly see this? He was certain he did--for a moment; and yet in that same moment he knew that the divine Babe was once more a babe of stone, with its sweet grave face and unconscious eyes; and when the Syndic turned again to watch the children, it was only the children he saw; the Angels were no longer visible. "It is not always given to our sinful eyes to see them," said Brother Agnolo, answering the Syndic's thought, "but whether we see them or see them not, always they are there." Now it was in the autumn of the same year that the fierce captain of Free-lances, the Condottiere Ghino, appeared one moonlight night before the gates of Spinalunga, and bade the guard open in the name of Pisa. As I have said, the little hill-town could only be attacked on the western side, on account of the precipitous ravine which divided it from the hills; but the ridge before the gate was crowded with eight hundred horsemen and two thousand men-at-arms clamouring to be admitted. Nothing daunted, the garrison on the square towers cried back a defiance; the war-bell was sounded; and the townspeople, men and women, hurried down to defend the walls.
