There was once a girl named Tarpeia, whose father was guard of the outer gate of the citadel of Rome. It was a time of war,—the Sabines were besieging the city. Their camp was close outside the city wall.
Tarpeia used to see the Sabine soldiers when she went to draw water from the public well, for that was outside the gate. And sometimes she stayed about and let the strange men talk with her, because she liked to look at their bright silver ornaments. The Sabine soldiers wore heavy silver rings and bracelets on their left arms,—some wore as many as four or five.
The soldiers knew she was the daughter of the keeper of the citadel, and they saw that she had greedy eyes for their ornaments. So day by day they talked with her, and showed her their silver rings, and tempted her. And at last Tarpeia made a bargain, to betray her city to them. She said she would unlock the great gate and let them in, if they would give her what they wore on their left arms.
The night came. When it was perfectly dark and still, Tarpeia stole from her bed, took the great key from its place, and silently unlocked the gate which protected the city. Outside, in the dark, stood the soldiers of the enemy, waiting. As she opened the gate, the long shadowy files pressed forward silently, and the Sabines entered the citadel.
As the first man came inside, Tarpeia stretched forth her hand for her price. The soldier lifted high his left arm. "Take thy reward!" he said, and as he spoke he hurled upon her that which he wore upon it. Down upon her head crashed—not the silver rings of the soldier, but the great brass shield he carried in battle!
She sank beneath it, to the ground.
"Take thy reward," said the next; and his shield rang against the first.
"Thy reward," said the next—and the next—and the next—and the next; every man wore his shield on his left arm.
So Tarpeia lay buried beneath the reward she had claimed, and the Sabines marched past her dead body, into the city she had betrayed.
