That salutary warning had been rung in Catharine's ears more than once, and was destined to be repeated again and again, with little effect: "All those who violate public faith are punished for it." L'Hospital had but a few months before been urging to a course of political integrity, and pointing out the rock on which all previous plans of pacification had split. There was but one way to secure the advantages of permanent peace, and that was an upright observance of the treaties formed with the Huguenots. But Catharine was slow to learn the lesson. Crooked paths, to her distorted vision, seemed to be the shortest way to success. Her Italian education had taught her that deceit was better, under all circumstances, than plain dealing, and she could not unlearn the long-cherished theory. Whether L'Hospital's views were originally the chief motives that influenced her in consenting to the peace of Longjumeau, or whether she had acquiesced in it as a cover to treacherous designs, certain it is that she now began to side openly with the chancellor's enemies, and that the Cardinal of Lorraine regained his old influence in the council. The fanatical sermons that had been a premonitory symptom of the previous wars were again heard with complacency in the court chapel; for, about the month of June, the king appointed as his preachers four of the most blatant advocates of persecution: Vigor, a canon of Notre Dame; De Sainte Foy; the gray friar, Hugonis; and Claude de Sainctes, whose acquaintance the reformers had made at the Colloquy of Poissy.[554] [Sidenote: Remonstrance of the three marshals.] [Sidenote: Catharine's intrigues.]
