The headstrong and forward temper of the person who was appointed his coadjutor crowned all his uneasiness. In effect, no body could be more the reverse of Grotius than Cerisante. The Memoirs of the Duke of Guise have placed this man in a very ridiculous light: his family indeed complain that the duke of Guise did not do him justice; but we know from others that he was as vain as he was inconsiderate. He was the son of Duncan, Minister of Saumur, and being perfect master of the Belles Lettres, he had been nominated Governor to the Marquis de Foix, who afterwards made him Lieutenant-Colonel of the regiment of Navarre; but a quarrel with the Duke of Candale in the beginning of Anne of Austria's regency obliged him to quit the kingdom. He retired into Sweden, in hopes that the Queen, who loved men of wit, would make his fortune. He was not disappointed: she gave him a commission to levy a regiment, which he never raised; and sent him into France with the titles of Colonel and Agent of Sweden. He soon laid aside that regard for Grotius which was recommended to him; and gave on all occasions proofs of his rash and vain-glorious humour. Grotius tells us that he sent very false intelligence to Sweden, which he affirmed that he had from the first hand: in short, he was guilty of so many extravagancies, that Queen Christina, being informed how little he was esteemed, and that she was in some sort censured on his account, dismissed him her service; but it was not till after Grotius's departure from Paris.
