Montaigne, on leaving Paris, stayed a short time at Blois, to attend the meeting of the States-General. We do not know what part he took in that assembly: but it is known that he was commissioned, about this period, to negotiate between Henry of Navarre (afterwards Henry IV.) and the Duke of Guise. His political life is almost a blank; but De Thou assures us that Montaigne enjoyed the confidence of the principal persons of his time. De Thou, who calls him a frank man without constraint, tells us that, walking with him and Pasquier in the court at the Castle of Blois, he heard him pronounce some very remarkable opinions on contemporary events, and he adds that Montaigne had foreseen that the troubles in France could not end without witnessing the death of either the King of Navarre or of the Duke of Guise. He had made himself so completely master of the views of these two princes, that he told De Thou that the King of Navarre would have been prepared to embrace Catholicism, if he had not been afraid of being abandoned by his party, and that the Duke of Guise, on his part, had no particular repugnance to the Confession of Augsburg, for which the Cardinal of Lorraine, his uncle, had inspired him with a liking, if it had not been for the peril involved in quitting the Romish communion. It would have been easy for Montaigne to play, as we call it, a great part in politics, and create for himself a lofty position but his motto was, ‘Otio et Libertati’; and he returned quietly home to compose a chapter for his next edition on inconveniences of Greatness.
The author of the Essays was now fifty-five. The malady which tormented him grew only worse and worse with years; and yet he occupied himself continually with reading, meditating, and composition. He employed the years 1589, 1590, and 1591 in making fresh additions to his book; and even in the approaches of old age he might fairly anticipate many happy hours, when he was attacked by quinsy, depriving him of the power utterance. Pasquier, who has left us some details his last hours, narrates that he remained three days in full possession of his faculties, but unable to speak, so that, in order to make known his desires, he was obliged to resort to writing; and as he felt his end drawing near, he begged his wife to summon certain of the gentlemen who lived in the neighbourhood to bid them a last farewell. When they had arrived, he caused mass to be celebrated in apartment; and just as the priest was elevating the host, Montaigne fell forward with his arms extended in front of him, on the bed, and so expired. He was in his sixtieth year. It was the 13th September 1592.
