ZAMET, SÉBASTIEN. - Bishop, b. in Paris in 1588, son of the financier Sebastiano; d. at Mussy on 2 February 1655.
Chaplain to Queen Maria de' Medici, on 6 April 1615 he was elected bishop of Langres and immediately worked in the Assembly of the Clergy to ensure that observance of the reform canons of the Council of Trent might finally be imposed in France; in his diocese he set an example through preaching, hearing confessions, and fostering the reform of religious women. He promptly became a member of the Compagnia del S.SACRAMENTI (v.) and was a friend of S. Vincenzo de' Paoli and of the most deserving reformers of his age.
From 1626 in Paris he was for some time the spiritual director of Angélique Arnaud, whom in 1633 he entrusted to his friend, Saint Cyran (v.). When the latter began to spread Jansenist doctrine and spirit, especially concerning Confession, Z. refuted him in two writings, one of which he had conveyed to Cardinal Richelieu, who consequently proceeded to arrest the celebrated abbé.
