raised enemies for him at court. The king, who valued Turquet, did his best to persuade him to conform to the Church of Rome as he himself had done, and to moderate the rancour of his professional foes. But he was unsuccessful in both efforts. Still Henri tried to keep him, ignoring his heresies, and perhaps rather sympathising with them.
