solidly teaching all men all things.” § 5. This work did not immediately see the light, but in 1631 Comenius published a book which made him and the little Polish town where he lived known throughout Europe and beyond it. This was the _Janua Linguarum Reserata_, or “Gate of Tongues unlocked.” Writing about it many years afterwards he says that he never could have imagined that that little work, fitted only for children (_puerile istud opusculum_), would have been received with applause by all the learned world. Letters of congratulation came to him from every quarter; and the work was translated not only into Greek, Bohemian, Polish, Swedish, Belgian, English, French, Spanish, Italian, Hungarian, but also into Turkish, Arabic, Persian, and even “Mongolian, which is familiar to all the East Indies.” (Dedication of _Schola Ludus_ in vol. i. of collected works.) § 6. Incited by the applause of the learned, Comenius now planned a scheme of universal knowledge, to impart which a series of works would have to be written, far exceeding what the resources and industry of one man, however great a scholar, could produce. He therefore looked about for a patron to supply money for the support of himself and his assistants, whilst these works were in progress. “The vastness of the labours I contemplate,” he writes to a Polish nobleman, “demands that I should have a wealthy patron, whether we look at their extent, or at the necessity of securing assistants, or at the expenses generally.” § 7. At Leszna there seemed no prospect of his obtaining the aid he required; but his fame now procured him invitations from distant countries. First he received a call to improve the schools of Sweden. After declining this he was induced by his English friends to undertake a journey to London, where Parliament had shown its interest in the matter of education, and had employed Hartlib,[66] an enthusiastic admirer of Comenius, to attempt a reform. Probably through his family connections, Hartlib was on intimate terms with Comenius, and he had much influence on his career. It would seem that Comenius, though never tired of forming magnificent schemes, hung back from putting anything into a definite shape. After the appearance of the _Janua Linguarum Reserata_, he planned a _Janua Rerum_, and even allowed that title to appear in “the list of new books to come forth at the next Mart at Frankford.”[67] But again he hesitated, and withdrew the announcement. Here Hartlib came in, and forced him into print without his intending or even knowing it (“præter meam spem et me inconsulto”; preface to _Conatuum Pansophicorum Dilucidatio_, 1638). Hartlib begged of Comenius a sketch of his great scheme, and with apologies to the author for not awaiting his consent, he published it at Oxford in 1637, under the title of _Conatuum Comenianorum Præludia_. Comenius accepted the _fait accompli_ with the best grace he could—pleased at the stir the book made in the learned
