In France the revival of these sanguinary sentiments served to increase reaction and to strengthen the party of the throne. In preference to such defenders of religion and the public good, people turned to the austere Royalists and Gallicans. The change was not final or complete, and did not carry all men with it. Imitators of Jacques Clement arose among the clergy, and Henry fell at last by the hand of a fanatic. When Mayenne sent the leaders of the populace to the scaffold, the defence became hopeless. Henry foiled his enemies by becoming a Catholic. He was not capable of taking dogmatic issues much to heart, and never ceased to hope for reunion, believing that the breach could be repaired, and that men who took pains to understand each other would find that there was no insurmountable obstacle to reconciliation. Many profited by the change who doubted his sincerity. But Henry was in the hands of Duperron, one of the most expert divines of modern times, who proved more than a match for Duplessis Mornay, and whom Casaubon, a better scholar than Duplessis Mornay, described as a thunderbolt of a man. Nobody supposed that he would have conformed if it had involved the sacrifice of the crown. It is not clear that it did actually involve the sacrifice of his conviction. The Pope, under Spanish influence, hesitated long to acknowledge him. It was a defeat and a humiliation to accept as eldest son of the Church an excommunicated heretic, who, by the law of the Supreme Tribunal, deserved to die, and to submit to him because he was victorious over Catholics of France and Spain. His elevation was a boon to the French, because he restored the prosperity of their Church; but it was none to Rome, because his belief was a compromise between Roman doctrine and ethics the reverse of Roman. The delicate negotiation was carried to a satisfactory end by Cardinal D'Ossat, whose despatches were long received, and perhaps still are, as the best in the language, and the model of all diplomacy. Spain followed Rome, and a conference was held under the presidency of the Pope, which concluded peace in the Treaty of Vervins. Then Philip II died, a defeated and disappointed man, whose schemes were wrecked by an inflexible intolerance; but with his military power undiminished, still the master of incomparable legions, still the ruler of the greatest empire in History.
