XVII. His brilliant success at the Bar, which he treats as ungrateful, procured him, however, a very considerable promotion. The place of Advocate-general of the Fisc for Holland and Zealand becoming vacant, it was unanimously conferred on Grotius. This is an employment of great distinction and authority, the person invested with it being charged with the preservation of the public peace and the prosecution of offenders. It was in 1607 he took possession of this important office, which he filled with so much reputation, the States augmented his salary, and promised him a seat in the Court of Holland. XVIII. John Grotius, on his son's being made Advocate-general, began to think of a wife for him; and fixed upon Mary Reigersberg, of one of the first families in Zealand, whose father had been Burgomaster of Veer: the marriage was solemnised in July, 1608. The greatest encomium of the new-married lady is, that she was worthy such a husband as Grotius. The most perfect harmony subsisted between them, and Grotius held her in the highest esteem[52]. This alliance gave occasion to a number of poems. John Grotius wrote his son's Epithalamium; Daniel Heinsius composed a Poem on that subject, which, in the opinion of Grotius, was the best of the kind that ever had been written. Grotius himself celebrated his nuptials in some Latin verses, approved of by Scaliger, and translated them into Dutch: he also wrote some in French on that occasion. FOOTNOTES: [52] Ep. 423. p. 876. XIX. At the time of his marriage he was employed in a work of great importance, which was not published till the year following. This was his _Freedom of the Ocean, or the Right of the Dutch to trade to the Indies_; dedicated to all the free nations of Christendom, and divided into thirteen Chapters. The author shews in the first, that by the law of Nations navigation is free to all the world: In the second, that the Portuguese never possessed the sovereignty of the countries in the East-Indies with which the Dutch carry on a trade: In the third, that the donation of Pope Alexander VI. gave the Portuguese no right to the Indies: In the fourth, that the Portuguese had not acquired by the law of arms the sovereignty of the States to which the Dutch trade: He shews in the fifth, that the ocean is immense and common to all; that it is absurd to imagine that those who first navigate a sea ought to be judged to have taken possession of it; that a vessel which cuts the waves of a sea, gives no more right to that sea, than she leaves marks of her way in it; that, besides, the Portuguese are not the first who sailed in the Indian sea, since there are facts which demonstrate it was neither unknown to the Ancients, to the Spaniards, nor to the Carthaginians, nor even to the Romans. The sixth chapter proves, that the right of navigation in that sea cannot belong exclusively to the Portuguese by virtue of Alexander VI's donation, because donation cannot take place in
