These chapbooks, embodying the folklore of past generations, were almost the first printed Judeo-German books, as they certainly were the most popular. That the early Judeo-German literature was intended mainly for readers in the east of Europe is amply evidenced by specific mention in the works themselves, as for example in the 'Maasebuch,' where the compiler, or author, urges the German women to buy quickly his book, lest it be all too fast sold in Bohemia, Poland, and Russia.[3] In fact, the patron of the 'Maasebuch,' or the author of the same, for it is not quite clear whether they are not one and the same person, was himself a native of Meseritz in Lithuania. Only after these story books had created a taste for reading, and in order to counteract the effects of the non-Jewish lore, the Rabbis began to substitute the more Jewish legends of the 'Maasebuch' and the 'Zeena Ureena,' and the ethical treatises which were intended to instruct the people in the tenets of their fathers. In this manner the Judeo-German literature was made possible. Its preservation for four centuries was mainly due to the isolation of the German Jews in Russia and Poland, where the German medievalism became ossified and was preserved intact to within half a century ago, when under favorable conditions the Russianization of the Jews began. Had these conditions prevailed but a short time longer, Judeo-German literature would have been a thing of the past and of interest only to the linguist and the historian. But very soon various causes combined to resuscitate the dialect literature. In the short time that the Jews had enjoyed the privileges of a Russian culture, then German medievalism was completely dispelled, and the modern period which, in its incipient stage, reaches back into the first quarter of this century, presents a distinct phase which in no way resembles the literature of the three hundred years that preceded it. It is not a continuation of its older form, but has developed on an entirely new basis.
