Du Vair died at Tonneins, August 3, 1621, six weeks after receiving Grotius's Letter. This was a great loss to him: but it would have been advantageously repaired, had the Seals, agreeable to the wishes of the Public, been given to the President Jeannin, the most esteemed Magistrate in the kingdom for his excellent talents and virtue. He had the highest friendship for Grotius, who ardently wished that great man might receive the reward of the signal services he had done the State: "But, he writes to Du Maurier[134], those who know the court, dare not flatter themselves with so much good luck." While the seals were vacant the Constable De Luynes did the office of keeper: they were at length given, not to the President Jeannin, but to De Vic, who had on all occasions given Grotius proofs of his friendship. He made profession of an esteem for men of learning; Casaubon held him in great veneration, and Grotius flattered himself that he would be his friend. "His behaviour to Casaubon, says Grotius to Du Maurier[135], proves his love to learning; and before he left Paris he gave me some evident marks of his good-will." It had been determined in the King's Council to do something for Grotius; but it was long before this resolution had its effect. Du Maurier had written to all his friends warmly to solicit the issuing of the warrant for the sum granted him: it was sent at length, but there was no money in the treasury. The King was absent, and when he returned to Paris, the thing, it was said, would be done. The Prince of Conde openly interested himself for him. What made Grotius uneasy was, that on the promises made him he had hired a house. His wife came to Paris in October, 1621[136], and their expences so much exceeded the small revenue which he had still left, that he wrote to Du Maurier, December 3, 1621, that if something were not done for him soon, he must seek a settlement in Germany, or hide himself in some corner of France. He asks a recommendation to the Chancellor De Silleri: "and as he is somewhat slow, it would be proper (says he) to refresh the Marquis de Puysieux's memory." The King returned to Paris January 30, 1622. Grotius was presented to him by the Chancellor and the Keeper of the seals in the beginning of March[137]: the Court was very numerous. His Majesty received him most graciously, and granted him a pension of three thousand livres. He was much obliged to the Prince of Conde and the Keeper of the Seals on this occasion. The King did not only confer marks of his favour on Grotius; but on his account protected all who were persecuted by the States; and by his Letters Patent, dated at Nantes, April 22, 1627, takes such as were condemned in Holland under his protection as if they were his own subjects; willing, that in case of death, their children and heirs should succeed, and that their effects should not be liable to be escheated.
