_A Reformation of Schooles_ was printed for Michael Sparke, London, 1642. _The History of the Bohemian Persecution_, which is one of the author’s church works, was completed in Bohemian in 1632, but was not published in that tongue until 1655. The date of the Latin version is 1647; of the English, 1650. Jeremy Collier’s rendering into English of the _Pansophiae_, or, as the translator entitled it, _Patterne of Universall Knowledge_, is dated, London, 1651. Published in 1643, in Danzig, it was printed two years later in Amsterdam. The Bohemian translation is quite recent, dating from 1879. “No one can impartially claim for Komenský a high rank as a philosopher,” comments Count Lützow, “and it is certainly a mistake to speak of Komenský’s system of philosophy. There is no philosophical system of Komenský in the sense that there exists a philosophical system of Spinoza.” _The Physicae_ or _Naturall Philosophie Reformed by Divine Light_ was printed in Leipsic in 1633, in Amsterdam 1643, 1645, 1663, etc. The Bohemian translation is recent. The English edition, in this catalogue, is of 1651. _The True and Readie Way to Learne the Latine Tongue_ appeared in Leszno, 1633. It was translated later into Dutch, English (our catalogue’s London edition is of 1654), Magyar, Swedish and Polish. The Latin-Bohemian-German edition is dated Trenčín, Hungary, 1649. Komenský’s most popular book, the _Orbis Sensualium Pictus_, was printed originally in Nuremberg, in 1658. The English translation by Charles Hoole followed one year later. The Latin-German-Magyar-Bohemian edition was issued in 1685; the first American edition, a reprint from Hoole’s twelfth London edition, in New York, in 1810. That the English translation of _The Great Didactic_, which Komenský wrote between 1627-1632 in the Bohemian language and in 1640 in Latin (published in Amsterdam, 1657), was not undertaken until our time (1896) is a matter of great surprise. The same comment is pertinent to Komenský’s most readable little volume, _The Labyrinth of the World and the Paradise of the Heart_, which strikingly reminds one of Bunyan’s _Pilgrim’s Progress_. It was only in 1905 that it found an able translator in the person of Count Lützow. _The Praxis Pietatis_, an oft-quoted book which passed through several editions in the seventeenth and eighteenth centuries has not been translated for the very good reason that it, in itself, was an adaptation, from the _Practice of Piety_, a volume by an English divine. _The Exhortation of the Churches of Bohemia to the Church of England_, Englished by Joshua Tymarchus and printed for Thomas Parkhurst, in Cheapside, 1661, was used eighty-seven years later as an argument and a plea by a distinguished English American, Gen. Oglethorpe.
