Voltaire, known as the protector of the innocent, was soon called upon to render a similar service for another family. A girl of the name of Sirven had been carried off from her Protestant family, and, according to the barbarous custom of the times, was shut up in a convent; where, not yielding to conversion as readily as was expected, she was treated with such severity that in a fit of desperation she threw herself into a well and was drowned. Instead of punishing the priests and nuns for the effects of their persecution, her family was accused of her death. They had time to escape, but were condemned to death for contumacy. The unfortunate father and mother resolved to apply to Voltaire. Reduced to destitution, they were forced to make the journey on foot, and presented themselves in a miserable state at Ferney. Voltaire was eager to raise his voice in their favour, though he was aware that the public, having lavished all their pity on the Calas would listen coldly to a new story. The spirit of toleration, which, nevertheless, he had spread abroad, served him in this case, as the enthusiasm of compassion had in the other; such delays, however, occurred, that the unfortunate mother died while the cause was yet pending. He could not obtain that the case should be tried in Paris. The accused were obliged to surrender to the parliament of Thoulouse. The principal people of that town had become eager to exonerate themselves from the charges of persecution and injustice which their former conduct had raised. The trial was carried on impartially, and Sirven was acquitted. Seven years, however, had elapsed before this tardy act of justice was completed. Another instance of religious intolerance, more frightful in some of its details than the preceding, roused Voltaire to combat the sanguinary clergy of his country with renewed zeal. But in this instance he could not save the victims already immolated by the malignancy of private enmity, and the cruel bigotry of public tribunals.
