world, but galled by criticisms, especially by doubts of his orthodoxy. To refute the cavillers, he wrote a tract called _Conatuum Pansophicorum Dilucidatio_ which was published in 1638. In 1639 Hartlib issued in London a new duodecimo edition of the _Præludia_ (or as he then called it, _Prodromus_) and the _Dilucidatio_, adding a dissertation by Comenius on the study of Latin. Now, when everything seemed ripe for a change in education, and Comenius himself was on his way to England, Hartlib translated the _Prodromus_, and when Comenius had come he published it with the title, _A Reformation of Schools_, 1642.[68] § 8. It was no doubt by Hartlib’s influence that Parliament had been led to summon Comenius, and at any other time the visit might have been “the occasion of great good to this island,” but _inter arma silent magistri_, and Comenius went away again. This is the account he himself has left us:— “When seriously proposing to abandon the thorny studies of Didactics, and pass on to the pleasing studies of philosophical truth, I find myself again among the same thorns.... After the _Pansophiæ Prodromus_ had been published and dispersed through various kingdoms of Europe, many of the learned approved of the object and plan of the work, but despaired of its ever being accomplished by one man alone, and therefore advised that a college of learned men should be instituted to carry it into effect. Mr. S. Hartlib, who had forwarded the publication of the _Pansophiæ Prodromus_ in England, laboured earnestly in this matter, and endeavoured, by every possible means, to bring together for this purpose a number of men of intellectual activity. And at length, having found one or two, he invited me also, with many very strong entreaties. My people having consented to the journey, I came to London on the very day of the autumnal equinox (September 22, 1641), and there at last learnt that I had been invited by the order of the Parliament. But as the Parliament, the King having then gone to Scotland [August 10], was dismissed for a three months’ recess [not quite three months, but from September 9 to October 20], I was detained there through the winter, my friends mustering what pansophic apparatus they could, though it was but slender.... The Parliament meanwhile, having re assembled, and our presence being known, I had orders to wait until they should have sufficient leisure from other business to appoint a Commission of learned and wise men from their body for hearing us and considering the grounds of our design. They communicated also beforehand their thoughts of assigning to us some college with its revenues, whereby a certain number of learned and industrious men called from all nations might be honourably maintained, either for a term of years or in perpetuity. There was even named for the purpose _The Savoy_ in London; _Winchester College_ out of London was named; and again nearer the city, _Chelsea
