"He," said the priestess, "who shall first kiss his mother on his return." The two brothers agreed that they would keep this a secret from their elder brother Sextus, and, as soon as they reached home, both of them rushed into the women's rooms, racing each to be the first to embrace their mother Tullia; but at the very entrance of Rome Brutus pretended to slip, threw himself on the ground and kissed his Mother Earth, having thus guessed the right meaning of the answer.
He waited patiently, however, and still was thought a fool when the army went out to besiege the city of Ardea; and while the troops were encamped round it, some of the young patricians began to dispute which had the best wife.

They agreed to put it to the test by galloping late in the evening to look in at their homes and see what their wives were about.

Some were idling, some were visiting, some were scolding, some were dressing, some were asleep; but at Collatia, the farm of another of the Tarquin family, thence called Collatinus, they found his beautiful wife Lucretia among her maidens spinning the wool of the flocks.

All agreed that she was the best of wives; but the wicked Sextus Tarquin only wanted to steal her from her husband, and going by night to Collatia, tried to make her desert her lord, and when she would not listen to him he ill-treated her cruelly, and told her that he should accuse her to her husband.

She was so overwhelmed with grief and shame that in the morning she sent for her father and husband, told them all that that happened, and saying that she could not bear life after being so put to shame, she drew out a dagger and stabbed herself before their eyes--thinking, as all these heathen Romans did, that it was better to die by one's own hand than to live in disgrace.
Lucius Brutus had gone to Collatia with his cousin, and while Collatinus and his father-in-law stood horror-struck, he called to them to revenge this crime.
