Although the Holy Land was the goal of ardent, longing hearts, yet it was no more a center for the dispersed of the Jewish race than it had been for a long time previous. It could not produce an original leader of any sort, and lived upon the crumbs of culture dropped by the Jews in Europe. The Kabbala, studied in Palestine since the time of Nachmani, was an exotic plant which could never flourish very well there, and degenerated into rankest superstition. The Holy Land did not even produce a Talmudical authority of widespread renown; also for earnest rabbinical studies it had become dependent upon Europe. The leadership of Judaism in the days after the death of Ben Adret and Asheri remained with Spain, not as formerly Aragon, but Castile, where the family of Asheri and their views prevailed. Here lived Talmudical authorities whose decisions were considered final. Here was still to be found, if not a flourishing state of science, at least appreciation of scientific research. In Castile, under the rule of the powerful and intelligent Alfonso XI, the Jews were in so prosperous a condition that, compared with other countries in Europe, this period may be called a Golden Age. Several clever Jews in succession, under the modest title of ministers of finance (Almoxarif), exercised an influence upon the course of politics. Not only the court, but also the great nobles, surrounded themselves with Jewish counselors and officers. In place of the humble, servile bearing, and the degrading badge which the church decreed for the Jews, the Jewish Spaniards still bore their heads erect, and clothed themselves in gold and silk. Dazzled by the glitter of this favorable state of affairs, some recognized the fulfillment of the old prophecy, "the scepter shall not depart from Judah," which Christians had so often employed in their attacks on Judaism.
