Had there been no disturbing element introduced in the national life of the German Jews, there would not have developed with them a specifically Judeo-German literature, even though they may have used the Hebrew characters in the transliteration of German books. Unfortunately, in the beginning of the sixteenth century, a large number of Jews, mainly from the region of the Middle Rhine, had become permanently settled in Bohemia, Poland, and Russia. Here they formed compact colonies in towns and cities, having been admitted to these countries primarily to create the nucleus of a town population, as the agricultural Slavs had been averse to town life. They had brought with them their patrimony of the German language, their German intellectual atmosphere and mode of life; and their very compactness precluded their amalgamation with their Slavic neighbors. Their numerical strength and spiritual superiority obliterated even the last trace of those Jews who had been resident in those regions before them and had spoken the Slavic dialects as their mother-tongues. Separated from their mother-country, they craved the intellectual food to which they had been accustomed there; but their relations with it were entirely broken, and they no longer took part in the mental life of their German contemporaries. The Reformation with its literary awakening could not exert any influence on them; they only turned back for reminiscences of ages gone by, and hungered after stories with which their ancestors had whiled away their hours of leisure in the cities along the Rhine. And so it happened that when the legendary lore of the Nibelungen, of Siegfried, of Dietrich of Bern, of Wigalois, of King Arthur, had begun to fade away even from the folk books of Germany, it lived on in the Slavic countries and continued to evoke pleasure and admiration.
