The goddess was indignant. On the Cynthian mountain top she thus addressed her son and daughter: "My children, I who have been so proud of you both and have been used to hold myself second to none of the goddesses except Juno alone, begin now to doubt whether I am indeed a goddess. I shall be deprived of my worship altogether unless you protect me." She was proceeding in this strain, but Apollo interrupted her. "Say no more," said he; "speech only delays punishment." So said Diana also. Darting through the air, veiled in clouds, they alighted on the towers of the city. Spread out before the gates was a broad plain where the youth of the city pursued their warlike sports. The sons of Niobe were there with the rest,--some mounted on spirited horses richly caparisoned, some driving gay chariots. Ismenos, the first-born, as he guided his foaming steeds was struck by an arrow from above. "Ah me!" he cried,--dropped the reins and fell lifeless. Another, hearing the sound of the bow, gave the rein to his horses and attempted to escape. The inevitable arrow overtook him as he fled. Two others, younger, stood wrestling breast to breast: one arrow pierced them both. Alphenor, an elder brother, hastened to the spot to render assistance, but fell in the act of brotherly duty. One only was left, Ilioneus. "Spare me, ye gods!" he cried, addressing all of them, in his ignorance that all needed not his supplication; and Apollo would have spared him, but the arrow had already left the string, and it was too late.
