daughter of Tanneguy Lefevre, professor of Greek at Saumur, in France. She early showed a fine genius, which her father cultivated with great care and satisfaction. After his death she went to Paris, whither her fame had already preceded her. She was then preparing an edition of Callimachus, which she published in 1674. Having shown some sheets of it to M. Huet, preceptor to the dauphin, and to several other men of learning at the court, the work was so highly admired, that the Duke of Montausier made a proposal to her of publishing several Latin authors for the use of the dauphin. She at first rejected this proposal, as a task to which she was not equal; but the duke insisting upon it, he at last gained her consent, and she undertook an edition of Florus, which was published in 1674. Her reputation being now diffused over all Europe, Christina, queen of Sweden, ordered Count Königsmarck to compliment her in the name of his mistress; upon which Mademoiselle Lefevre sent the queen a Latin letter, with her edition of Florus, to which her majesty wrote an obliging answer, and not long afterwards wrote another letter to persuade her to abandon the Protestant religion, and to settle at the Swedish court. In 1683 she married M. Dacier, upon which occasion it was pleasantly remarked that this was the marriage of the Greek and the Latin; and she soon afterwards declared her design to the Duke of Montausier and the Bishop of Méaux, of reconciling herself to the church of Rome, which she had entertained for some time; but as M. Dacier was not yet convinced of the reasonableness of such a change, they retired in 1684 to Castres, where they had a small estate, in order to examine the points of controversy between the Protestants and the Roman Catholics. They at last determined in favour of the latter, and made a public abjuration of Protestantism in 1685. After this, the king gave both the husband and wife marks of his favour. In 1693 she applied herself to the education of her son and daughter, who made great progress; but the son died in 1694, and the daughter became a nun in the abbey of Longchamp. Madame Dacier had another daughter, who united in her all the virtues and accomplishments that could adorn the sex; but she unfortunately died at the age of eighteen. Her mother has immortalized her memory in the preface to her translation of the Iliad. Madame Dacier was in a very infirm state of health the two last years of her life; and she died, after a very painful sickness, on the 17th of August 1720, aged sixty-nine. She was remarkable for her firmness, generosity, equality of temper, and piety.
