The author of _Vindiciae Grotianae_ assures us[554], after Morhof, that Grotius's Letters are not all printed; and he adds, that he knew a cabinet in which were preserved upwards of two hundred and sixty, written to Queen Christina and the High Chancellor. Bunau, a Privy Counselor at Dresden, is said to have had many of them. Puffendorf saw several in cypher, to which he had a key. Among those, which are printed in the collection of Grotius's letters, there are some in cypher, relating to the general affairs and secret intrigues of the Court of France. M. de Boze has a copy of these letters in his curious cabinet, with an explanation of the cypher, given him by a Swedish gentleman, which he communicates to those who desire it, with a politeness that it were to be wished were common to all men of learning.

One of the most interesting parts of Grotius's life is the knowledge of his sentiments in religion, and the ardent zeal with which he undertook to reunite Christians in one belief. Brought up in the principles of Protestantism, he had in the former part of his life a great aversion to Popery. A letter to Antony Walaeus, Nov. 10, 1611[555], in which he opens all his mind, acquaints us, that however much he might be attached to the prevailing religion in the State wherein he lived, he was persuaded that the Roman Catholics held all the fundamental truths; but they superadded, he thought, several other articles, which he treated as new opinions. The zeal of the Jesuits for the Roman Catholic religion, and their attachment to the Pope, had rendered them extremely odious to all the enemies of the Romish church. Grotius viewed them in the same light, agreeably to the sentiments which had been instilled into him in his infancy, as we find in a letter written, April 1, 1617[556], to his brother then in France; but when he came to riper years, he did them justice, highly valuing their society, and receiving many of them into his confidence, particularly the learned Dionysius Petavius.
