Philological Works; the eighth, Poetical Translations, the Anthologia, Stobaeus, and the Extracts from the Tragedies and Comedies; and, lastly, the ninth, his Poems and Letters.  It is probable, that this design was defeated by Grotius’s departure from Holland.  It was not till long after, in 1679, that the handsome edition of Grotius’s theological works was published in three volumes in folio, dedicated to King Charles II. of England by Peter Grotius, Feb. 28, 1678.  The bookseller promised, in an advertisement prefixed to it, to print all Grotius’s other works, even those that had never been published; but he did not fulfil his engagements.

Grotius’s enemies still opposing his son’s advancement, he entered into the service of Charles Lewis, Elector Palatine, to whom Hugo Grotius had done singular service during his misfortunes.  This Prince nominated him his Agent at the Hague.

The ferment in mens minds having subsided, and the face of affairs being changed in Holland, Peter Grotius was nominated Pensionary of Amsterdam in 1660; which important place he filled for seven years with great reputation.  This office was the height of Hugo’s wishes for his son.  The Count D’Estrade, at that time Ambassador from France in Holland, was dissatisfied with the Pensionary of Amsterdam, who opposed the interest of the French King, in resentment of that Prince’s having driven Mombas, Peter Grotius’s brother-in-law, out of France.  Feb. 1, 1633, he writes to the King, “I have not been at Amsterdam, because the Pensionary M. de Groot is brother-in-law to M. de Mombas, whom your Majesty ordered to quit the kingdom for some affair in which you were dissatisfied with his conduct:  since that time M. de Groot has constantly opposed your Majesty’s interest at Amsterdam.  He is a man of spirit and firmness; and has much credit in that city.  I shall neglect nothing to bring him back to his former sentiments.”  The King answered him, May 23, 1633, that he had had reason to be dissatisfied with Mombas’s conduct; that if any consideration could make him forget it, it would certainly be a regard for M. de Groot, whose person, says the King, I esteem:  In fact, Lewis XIV, as he writes to his Ambassador, Sept. 22, 1665, dropt his resentment against Mombas out of consideration for the Pensionary of Amsterdam.  After the conclusion of the triple alliance, the necessity of regulating the subsidies with the northern powers induced the States of Holland to send Grotius to Denmark and Sweden.  He went first to Copenhagen, and afterwards to Stockholm, where he assumed the quality of Ambassador in ordinary.  The States used only to keep a Minister of the second rank at this Court; but it was thought proper, says Wicquefort, to do something more than common for such an extraordinary person; and he was ordered to make a splendid entry at the expence of the States.
