When Grundtvig presented this plan to his remaining friends, they received it at once with enthusiasm and began the organization of societies both in Denmark and Norway for the purpose of sponsoring its execution, in itself a most herculean task. The two books contain together about fifteen hundred large and closely printed pages and present a circumstantial account of the early mythological and factual history of the two nations. Even a merely literal translation of them might well consume years of labor. But Grundtvig's plan went much farther than mere literal translation. Wishing to appeal to the common people, he purposed to popularize the books and to transcribe them in a purer and more idiomatic Danish than the accepted literary language of the day, a Danish to be based on the dialects of the common people, the folk-songs, popular proverbs, and the old hymns. It was a bold undertaking, comparable to the work of Luther in modelling the language of the German Bible after the speech of the man in the street and the mother at the cradle, or to the great effort of Norway in our days to supplant the Danish-Norwegian tongue with a language from the various dialects of her people. Nor can it be said that Grundtvig was immediately successful in his attempt. His version of the sagas sounds somewhat stilted and artificial, and it never became popular among the common people for whom it was especially intended. Eventually, however, he did develop his new style into a plain, forceful mode of expression that has greatly enriched the Danish language of today. For seven years Grundtvig buried himself in "the giant's mount," emerging only occasionally for the pursuit of various studies in connection with his work or to voice his views on certain issues that particularly interested him. He discovered a number of errors in the Icelandic version of Beowulf and made a new Danish translation of that important work; he engaged in a bitter literary battle with Paul Mueller, a leader among the younger academicians, in defence of the celebrated lyric poet, Jens Baggesen, who had aroused the wrath of the students by criticising their revered dramatist, Oehlenschlaeger; and he fought a furious contest with the greatly admired song and comedy writer, John L. Heiberg, in defence of his good friend, Bernhard Severin Ingemann, whose excellent but overly sentimental lyrics had invited the barbed wit of the humorist. But although Grundtvig's contributions to these disputes were both able and pointed, their main effect was to widen the breach between him and the already antagonistic intellectuals.
