Each chapter of the _Janua_ is to be read ten times. In the first reading there is to be an accurate translation into the vernacular; at the second reading the whole is to be written out, Latin and vernacular, and the teacher is to begin conversation in the Latin tongue. At the third reading the teacher is to read the Latin aloud, and the pupils are to translate into the vernacular without seeing the printed page. At the fourth reading the grammar is to be written out and the words parsed. Special attention is to be given to the derivation of words at the fifth reading; the synonyms to be explained at the sixth; and the grammatical rules applied at the seventh. At the eighth reading the pupils are to learn the text by heart. The ninth reading is to be devoted to a logical analysis of the subject-matter; and the tenth and last reading is to be conducted by the pupils themselves. They are to challenge one another to repeat portions of the text. In this ingenious manner Comenius applies his long-cherished pansophic theories to language teaching, the _Janua_ being an application of ideas formulated in the _Great didactic_. It is, however, more than an application of pansophic notions—it is an attempt to realize his oft-enunciated educational maxim that words and things should never be divorced, that knowledge of the language should go hand in hand with the knowledge of the things explained. The success of the _Janua_ was most unexpected, and no one was more surprised at its sudden popularity than Comenius himself. “That happened,” he writes, “which I could not have imagined, namely, that this childish book was received with universal approbation by the learned world. This was shown me by the number of men who wished me hearty success with my new discovery; and by the number of translations into foreign languages. For, not only was the book translated into twelve European languages, since I myself have seen these translations (Latin, Greek, Bohemian, Polish, German, Swedish, Dutch, English, French, Spanish, Italian, and Hungarian), but also into the Asiatic languages—Arabic, Turkish, and Persian—and even into the Mongolian, which is understood by all the East Indies.”
