Rigorously treated at first, his docility and resignation soon won the respect and affection of his keepers. Writing materials and books were in time accorded him, and finally, on condition that she would continue to share his captivity, he was granted the presence of his wife. The studious prisoner and his devoted companion completely disarmed all suspicion of an intention to escape, and the ponderous chest in which books came and went continued to bring periodic consolation to the mind of the busy scholar. A treatise on the truth of the Christian religion, a catechism for the use of his children, a digest of Dutch law, and other compositions served to occupy and alleviate the weary months of confinement, until one day when the time seemed opportune Madame Grotius secretly inclosed her husband in the great chest and it was borne away by two soldiers. Descending the stone steps of the prison the bearers remarked that the trunk was heavy enough to contain an Arminian, but Madame Grotius's jest on the heaviness of Arminian books smoothed over the suspicion, if one was really entertained, and the great jurist was sent in the chest safe to Gorcum, attended by a faithful domestic, where in the house of a friend the prisoner emerged without injury and in the guise of a stone mason hastened to Antwerp. From Antwerp he took refuge in France, where he arrived in April, 1621, and was joined by his faithful wife at Paris in the following October. The bitterness of exile was now to be added to the miseries of imprisonment, for Grotius was not only excluded from The Netherlands, but in extreme poverty. His letters reveal his anguish of spirit at this period, but a generous Frenchman, Henri de Même, placed his country house at Balagni at his disposition, and there, supported by a small pension, which Louis XIII had graciously accorded him, though irregularly and tardily paid, Grotius commenced his great work, "_De Jure Belli ac Pacis_," in the summer of 1623. Much speculation has been indulged in regarding the causes which led to the composition of this masterpiece, but a recent discovery has rendered all this superfluous, as well as the ascription of special merit to the Counselor Peyresc for suggesting the idea of the work. It is, indeed, to the pacific genius of Grotius more than to all other causes that the world owes the origin of his great work; for it sprang from his dominant thought, ever brooding on the horrors of war and the ways of peace, during more than twenty years, and never wholly satisfied till its full expression was completed.
