The English text is unchanged from that of the 1727 edition, except in rare instances where substitutions have been made for single words not now permissible. The typography suggests rather than imitates the quaintness of the original, and the paper was carefully selected to produce so far as practicable the impression of the old hand-presses. In short my aim has been to put within the reach of teachers at a moderate price a satisfactory reproduction of this important book; and if the sale of the _Orbis Pictus_ seems to warrant it, I hope subsequently to print as a companion volume the _Vestibulum_ and _Janua_ of the same author, of which I have choice copies. C. W. BARDEEN. _Syracuse, Sept. 28, 1887_. COMMENTS UPON THE ORBIS PICTUS. During four years he here prosecuted his efforts in behalf of education with commendable success, and wrote, among other works, his celebrated Orbis Pictus, which has passed through a great many editions, and survived a multitude of imitations. --SMITH’S HISTORY OF EDUCATION, N.Y., 1842, p. 129. The most eminent educator of the seventeenth century, however, was John Amos Comenius...... His Orbis Sensualium Pictus, published in 1657, enjoyed a still higher renown. The text was much the same with the Janua, being intended as a kind of elementary encyclopædia; but _it differed from all previous text-books_, in being illustrated with pictures, on copper and wood, of the various topics discussed in it. This book was universally popular. In those portions of Germany where the schools had been broken up by the “Thirty years’ war,” mothers taught their children from its pages. Corrected and amended by later editors, it continued for nearly two hundred years, to be a text-book of the German schools. --HISTORY AND PROGRESS OF EDUCATION, BY PHILOBIBLIUS, N.Y., 1860, p. 210. The “Janua” would, therefore, have had but a short-lived popularity with teachers, and a still shorter with learners, if Comenius had not carried out his principle of appealing to the senses, and called in the artist. The result was the “Orbis Pictus,” a book which proved a favorite with young and old, and maintained its ground in many a school for more than a century.... I am sorry I cannot give a specimen of this celebrated book with its quaint pictures. The artist, of course, was wanting in the technical skill which is now commonly displayed even in the cheapest publications, but this renders his delineations none the less entertaining. As a picture of the life and manners of the seventeenthcentury, the work has great historical interest, which will, I hope, secure for it another English edition. --QUICK’S EDUCATIONAL REFORMERS, 1868; Syracuse edition, p. 79.
