We have in these pages followed their ideas--Saadia, Gabirol, Ibn Zaddik, Abraham Ibn Daud. The latter in particular anticipated Maimonides in almost all his ideas. None had the effect of upsetting the theological equilibrium of Jewry. Everyone had his admirers, no doubt, as well as his opponents. Gabirol was forgotten, Ibn Zaddik and Ibn Daud were neglected, and Jewish learning continued the even tenor of its course. Maimonides was the first to make a profound impression, the first who succeeded in stirring to their depths the smooth, though here and there somewhat turbid, Rabbinic waters, as they flowed not merely in scientific Spain and Provence, or in the Orient, but also in the strictly Talmudic communities of northern France. It was the Commentary on the Mishna and the Talmudic code known as the "Yad ha-Hazaka" that was responsible for the tremendous effect of the "More Nebukim" ("Guide of the Perplexed"). In these two Rabbinical treatises, and particularly in the "Yad ha-Hazaka," the Rabbinic Code, Maimonides showed himself the master of Rabbinic literature. And all recognized in him the master mind. Having been written in Hebrew the Code soon penetrated all Jewish communities everywhere, and Maimonides's fame spread wherever there were Jews engaged in the study of the Talmud. His fame as a court physician in Egypt and as the official head of Oriental Jewry enhanced the influence of his name and his work. Jealousy no doubt had its share in starting opposition to the Code itself even before the publication of the "Guide," and during the lifetime of its author. When the "More Nebukim" was translated from the original Arabic into Hebrew, so that all could read it, and Maimonides was no longer among the living, the zealots became emboldened and the storm broke, the details of which, however, it is not our province to relate. For completeness' sake let us set down the facts of his life. Moses ben Maimon was born in the city of Cordova on the fourteenth of Nissan (30th of March) at one o'clock in the afternoon, on a Sabbath which was the day before Passover, in the year 1135. It is not often that the birth of a mediæval Jewish writer is handed down with such minute detail. Usually we do not even know the year, to say nothing of the day and the hour. Cordova had long fallen from its high estate. It was no longer the glorious city of the days before the Almoravid conquest. And it was destined to descend lower still when the fanatical hordes of the Almohades renewed the ancient motto of the early Mohammedan conquerors, "The Koran or the Sword."
