Colomiez, in his Bibliotheque choisie[711], has collected some of the Elogiums which had been then made of Grotius: "The President Jeannin, says he, according to the relation of Balzac, opposes Grotius to the greatest men of antiquity. Salmasius, in his notes on Solinus, styles him Virum excellentissimæ doctrinæ in omni genere litterarum; Selden, in his Mare clausum, virum acuminis et omnigenæ doctrinæ præstantiâ incomparabilem; Gerard Vossius, in his Latin Poems, Seculi nostri grande ornamentum; Pricæus, on the xivth of St. Matthew, Virum ingentem, quem non sine horrore mirati sumus: In fine, M. Blondel, who was not lavish of his praise, says of him in his Sibyls, that he was a very great man, whether we consider the sublimity of his genius, the universality of his learning, or the diversity of his writings; in fine, says Colomiez[712], he appears a great critic in his Martianus Capella, his Aratus, and his Stobæus; in his Notes on Lucan and Tacitus a great historian, a great statesman, a great divine; but however excellent these different works may be, we must however acknowledge that Grotius's Letters and Poems much surpass them; and that if he appeared great in those, in these he is incomparable. But what astonishes me is, that he should have written so many letters, and made so many verses, and all should be of equal strength, that is, that all should partake of the powerful and divine genius which animated that great man." Episcopius, who was regarded as an oracle by his party, looked on Grotius as his oracle. "Your opinion, he writes to him[713], shall be to me the decision of an oracle; for I know your love to truth and friendship for me to be such, that in giving it you regard only truth."
Christian Habsoeker and Philip Limborch speak of him with raptures in the Preface to the Letters of illustrious men: "At the name of the incomparable Grotius, who is above all praise, and even all envy, we are in a sort of transport. How shall we sufficiently praise the virtues of that most illustrious hero, whom all true scholars regard as the most learned of the Learned: we shall only relate the prophecy concerning him in 1614 by Daniel Heinsius in some verses which ought to be put under his picture."
Those lines are in fact the most complete Elogium that can be made of a man.
Depositum Coeli, quod jure Batavia mater
Horret, et baud credit se peperisse sibi;
Talem oculis, talem ore tulit se maximus Hugo:
Instar crede hominis, cætera crede Dei.
Heinsius and Grotius had been most intimate in their youth: the divisions which happened in the Republic destroyed this close union: Heinsius joined the Contra-Remonstrants, and was Secretary to the Commissioners of the Synod of Dort. Grotius had reason to complain of him on several occasions: nevertheless, talking with Cardinal Richelieu about him, Grotius greatly commended his genius and learning. He gives an account of this conversation to his brother; adding, "In this manner I am wont to revenge myself on those who hate me." Cardinal Richelieu, though not prejudiced in favour of Grotius, ranked him however among the three first scholars of the age: the other two were Claudius Salmasius, and Jerom Bignon. This famous Advocate-General said of Grotius[714], that he was the most learned man who had appeared in the world since Aristotle.
Foreigners who loved the sciences would not leave France without seeing Grotius. John Christenius, who was at Paris in 1629, had more satisfaction in seeing him, than in the whole kingdom beside: he writes thus to John Kirkman, June 20, 1629. "The pleasure I have had, received considerable addition not only from having seen, but also often conversed with that great and eloquent man who has no fellow, I mean Hugo Grotius; for whom I have the highest esteem, and have been for many years of the same opinion with all who know that he possesses singly what would be sufficient to entitle many to great praise. He is master of all that is worth knowing in sacred and profane literature. Besides the Eastern languages, there is no art nor science with which he is not perfectly acquainted: this appears from his agreeable conversation: ask him about any thing, he immediately gives you an exact answer, and in such a manner as to excite the admiration of those who hear him. After talking about the sciences, if you enquire of him what passes in this part of the world, or the other, you will imagine you heard the answer of an oracle who delivers what is most worthy to be known. His virtue is above all I can say of it, and I want eloquence sufficiently to extol so great a man."
Sarrau[715], who had been prejudiced against Grotius since his leaving the Protestants, ventures not however to decide whether Salmasius or Grotius excelled in literature; and he hesitates to make the determination, even in a letter written to Salmasius, wherein he appears much dissatisfied with Grotius. "Whether the first place in literature in this age be due to you or to him, posterity will judge more equitably than this generation."
On hearing of Grotius's death, he writes to Salmasius in these terms[716]: "Hugo Grotius was certainly a great man in name and in fact: he was the star of our age. How great a loss has learning sustained! Whilst books and sciences are held in honour his name will flourish. For my part, whilst I live I shall glory in my intimacy with him. You now reign singly (he concludes, addressing himself to Salmasius) I pray God you may reign long." He calls him elsewhere[717] the Coryphæus of learning sacred and prophane.
Queen Christina, hearing of his death, wrote to his widow to make her compliments of condolence, and to get the manuscripts he left. "My Ambassador, she says, may have acquainted you in part with my high esteem for his admirable learning and the good services he did me: but he could not express how dear I hold his memory, and the effects of his great labours. If gold and silver could contribute any thing to the redeeming such a valuable life, I would chearfully employ all I am mistress of for that purpose." She concludes with asking his widow to procure her all the manuscripts of this learned man, whose works had always given her great pleasure: assuring her that they could not fall into better hands, and that the author having been of use to her in his life-time, it was just that she should not be deprived after his death of the fruits of his illustrious labours.
Duncomius wrote to Gerard Vossius, February 2, 1646[718], "It is certain and beyond dispute that Grotius was a very illustrious hero, usque ad stuporem ferè et miraculum; that he joined science with wisdom; that he was above all praise; and that he was deeply skilled in divine and human learning."
