Frightened at the outburst, the women removed the wreaths from their heads, left their sacrifices and slunk home, still honoring Latona with silent prayer.
On the summit of the Delian mountain Cynthas stood Latona with her two children, watching what was taking place in distant Thebes. "See, my children," she said, "I, your mother, who am so proud of your birth, who yield place to no goddess except Juno, I am held up to ridicule by an upstart mortal, and if you do not defend me, my children, I shall be driven away from the ancient and holy altars. Yes, you too are insulted by Niobe, and she would like to have you set aside for her children!"
Latona was about to go on, but Apollo interrupted her: "Cease your lamentations, mother; you only delay the punishment."
Then he and his sister wrapped themselves in a magic cloud cloak that made them invisible, and flew swiftly through the air until they reached the town and castle of Cadmus.
Just outside the walls of the city was an open field that was used as a race-course and practice ground for horses. Here the seven sons of Amphion were amusing themselves, when suddenly the oldest dropped his reins with a cry and fell from his horse, pierced to the heart by an arrow. One after another the whole seven were struck down.
The news of the disaster soon spread through the city. Amphion, when he heard that all his sons had perished, fell on his own sword. Then the loud cries of his servants penetrated to the women's quarters.
For a long time Niobe could not believe that the gods had thus brought vengeance. When she did, how unlike was she to the Niobe who drove the people from the altars of the mighty goddess and strode through the city with haughty mien. Crazed with grief she rushed out to the field where her sons had been stricken, threw herself on their dead bodies, kissing now this one and now that. Then, raising her arms to heaven, she cried, "Look now upon my distress, thou cruel Latona; for the death of these seven bows me to the earth. Triumph thou, O my victorious enemy!"
Now the seven daughters of Niobe, clad in garments of mourning, drew near, and with loosened hair stood around their brothers. And the sight of them brought a ray of joy to Niobe's white face. She forgot her grief for a moment, and casting a scornful look to heaven, said, "Victor! No, for even in my loss I have more than thou in thy happiness!"
