Komenský, now sixty-five years old, was again homeless, and he was at first uncertain where he should seek refuge. He proceeded to Hamburg, but there received an invitation to Amsterdam from Lawrence De Geers, the son of his old patron Louis De Geers. Komenský started for Amsterdam, and here spent the latest years of his life. His literary activity continued to the last. He published at Amsterdam the only complete edition of his educational works, and even wrote new "pansophic" books. Differing on this point from his father, Lawrence De Geers took great interest in these studies, and even in the writings of the "prophets," in whom Komenský obstinately continued to believe. De Geers was foolish enough to invite Drabik to Amsterdam, and it was through his financial aid that Komenský was enabled to publish in 1657 his _Lux in Tenebris_, a book in which all the prophecies of Kotter, Ponatovská, and Drabik were again brought before the public. The mystic and now openly professed chiliastic views of Komenský involved him during the last years of his life in numerous theological controversies. Detailed accounts of them have recently been published in Bohemian, perhaps rather because everything concerned with Komenský is valued by his countrymen than because these controversies now have much interest. Among Komenský's theological antagonists were Nicholas Arnold, Daniel Zwicker, and Samuel Des Marets, a professor at Gröningen. The last-named attacked the aged bishop of the Unity with great violence, calling him "a fanatic, a visionary, and an enthusiast in folio." He also accused him of obtaining large sums from the De Geers family by means of "pansophic hope and chiliastic smoke." A polemical essay directed against Descartes also belongs to Komenský's last years. These years were very melancholy, though the old man, characteristically enough, found great relief in the society of an aged French prophetess and visionist named Antoinette Bourgignon. His old comrades died off one by one. Of the bishops of the community, Gertichius died in 1667, and Figulus (Komenský's son-in-law) in January 1670. In the same year, on November 15th, Komenský, the last bishop of the Bohemian Brethren, ended his long and troubled life. It would require a book larger than the whole of this volume to give even a slight account of the 142 works[109] of Komenský. Such a book would hardly have much general interest. The enormous total includes prayer-books, lists of regulations for the Unity, mere school-books, sermons, works on natural history that long since have become valueless, and so on. These lists, however, which include only books that are still in existence, do not comprise the entire fruits of the literary activity of Komenský. Several "pansophic" works that are enumerated in a table of contents, to which I have already referred, are no longer in existence, and were probably destroyed when the town of Lissa was burnt down.
