The Roman attitude towards women and rape was such that rape was a property crime against the husband or paterfamilias. The story of Lucretia (who stabbed herself rather than allow her name to go through posterity tainted) epitomizes the shame felt by Roman victims.
Lucretia had been such a model of Roman feminine virtue that she inflamed the lust of Sextus Tarquin, the son of the king, Tarquinius Superbus, to the point that he arranged to accost her in private. When she resisted his pleas, he threatened to place her naked, dead body beside that of a male slave in the same state so that it would look like adultery. The threat worked and Lucretia permitted the violation.
Following the rape, Lucretia told her male relatives, elicited a promise for revenge, and stabbed herself. [Source: Livy]
Shortly after the rape of Lucretia, the Romans rebelled against their king, the last Roman king was overthrown, and the Roman Republic began.
From Livy Book 1 Heinemann translation (1919):
"57. It chanced, as they were drinking in the quarters of Sextus Tarquinius, where Tarquinius Collatinus, son of Egerius, was also a guest, that the subject of wives came up.  Every man fell to praising his own wife with enthusiasm, and, as their rivalry grew hot, Collatinus said that there was no need to talk about it, for it was in their power to know, in a few hours' time, how far the rest were excelled by his own Lucretia.  “Come! If the vigour of youth is in us let us mount our horses and see for ourselves the disposition of our wives. Let every man regard as the surest test what meets his eyes when the woman's husband enters unexpected.” They were heated with wine. “Agreed!”  they all cried, and clapping spurs to their horses were off for Rome. Arriving there at early dusk, they thence proceeded to Collatia, where Lucretia was discovered very differently employed from the daughters-in-law of the king.  These they had seen at a luxurious banquet, whiling away the time with their young friends; but Lucretia, though it was late at night, was busily engaged upon her wool, while her maidens toiled about her in the lamplight as she sat in the hall of her house.  The prize of this contest in womanly virtues fell to Lucretia. As Collatinus and the Tarquinii approached, they were graciously received, and the victorious husband courteously invited the young princes to his table. It was there  that Sextus Tarquinius was seized with a wicked desire to debauch Lucretia by force; not only her beauty, but her proved chastity as well, provoked him.  However, for the present they ended the boyish prank of the night and returned to the camp.
58. When a few days had gone by, Sextus Tarquinius, without letting Collatinus know, took a single attendant and went to Collatia.  Being kindly welcomed, for no one suspected his purpose, he was brought after dinner to a guest-chamber. Burning with passion, he waited till it seemed to him that all about him was secure and everybody fast asleep; then, drawing his sword, he came to the sleeping Lucretia. Holding the woman down with his left hand on her breast, he said, “Be still, Lucretia! I am Sextus Tarquinius. My sword is in my hand. Utter a sound, and you die!” In affright the woman started out of her sleep.  No help was in sight, but only imminent death. Then Tarquinius began to declare his love, to plead, to mingle threats with prayers, to bring every resource to bear upon her woman's heart.  When he found her obdurate and not to be moved even by fear of death, he went farther and threatened her with disgrace, saying that when she was dead he would kill his slave and lay him naked by her side, that she might be said to have been put to death in adultery with a man of base condition.  At this dreadful prospect her resolute modesty was overcome, as if with force, by his victorious lust; and Tarquinius departed, exulting in his conquest of a woman's honour. Lucretia, grieving at her great disaster, dispatched the same message to her father in Rome and to her husband at Ardea:  that they should each take a trusty friend and come; that they must do this and do it quickly, for a frightful thing had happened. Spurius Lucretius came with Publius Valerius, Volesus' son.  Collatinus brought Lucius Junius Brutus, with whom he chanced to be returning to Rome when he was met by the messenger from his wife. Lucretia they found sitting sadly in her chamber. The entrance of her friends brought the tears to her eyes, and to her husband's question, “Is all well?”  she replied, “Far from it; for what can be well with a woman when she has lost her honour? The print of a strange man, Collatinus, is in your bed. Yet my body only has been violated; my heart is guiltless, as death shall be my witness. But pledge your right hands and your words that the adulterer shall not go unpunished. Sextus Tarquinius is he that last night returned hostility for hospitality, and armed with force brought ruin on me, and on himself no less —if you are men —when he worked his pleasure with me.”  They give their pledges, every man in turn. They seek to comfort her, sick at heart as she is, by diverting the blame from her who was forced to the doer of the wrong.  They tell her it is the mind that sins, not the body; and that where purpose has been wanting there is no guilt.  “It is for you to determine,” she answers, “what is due to him; for my own part, though I acquit myself of the sin, I do not absolve myself from punishment; not in time to come shall ever unchaste woman live through the example of Lucretia.”  Taking a knife which she had concealed beneath her dress, she plunged it into her heart, and sinking forward upon the wound, died as she fell.  The wail for the dead was raised by her husband and her father. "
