This is the development of Jewish poetry during its great period. In other departments of literature, in philosophy, in theology, in ethics, in Bible exegesis, the race is equally prolific in minds of the first order. Glancing back for a moment, our eye is arrested by Moses Maimonides, the great systematizer of the Jewish Law, and the connecting link between scholasticism and the Greek-Arabic development of the Aristotelian system. Before his time Bechaï ibn Pakuda and Joseph ibn Zadik had entered upon theosophic speculations with the object of harmonizing Arabic and Greek philosophy, and in the age immediately preceding that of Maimonides, Abraham ibn Daud, a writer of surprisingly liberal views, had undertaken, in "The Highest Faith," the task of reconciling faith with philosophy. At the same time rationalistic Bible exegesis was begun by Abraham ibn Ezra, an acute but reckless controversialist. Orthodox interpretations of the Bible had, before him, been taught in France by Rashi (Solomon Yitschaki) and Samuel ben Meïr, and continued by German rabbis, who, at the same time, were preachers of morality--a noteworthy phenomenon in a persecuted tribe. "How pure and strong its ethical principles were is shown by its religious poetry as well as by its practical Law. What pervades the poetry as a high ideal, in the application of the Law becomes demonstrable reality. The wrapt enthusiasm in the hymns of Samuel the Pious and other poets is embodied, lives, in the rulings of Yehuda Hakohen, Solomon Yitschaki, and Jacob ben Meïr; in the legal opinions of Isaac ben Abraham, Eliezer ha-Levi, Isaac ben Moses, Meïr ben Baruch, and their successors, and in the codices of Eliezer of Metz and Moses de Coucy. A German professor[13] of a hundred years ago, after glancing through some few Jewish writings, exclaimed, in a tone of condescending approval: 'Christians of that time could scarcely have been expected to enjoin such high moral principles as this Jew wrote down and bequeathed to his brethren in faith!'" Jewish literature in this and the next period consists largely of theological discussions and of commentaries on the Talmud produced by the hundred. It would be idle to name even the most prominent authors; their works belong to the history of theologic science, and rarely had a determining influence upon the development of genuine literature. We must also pass over in silence the numerous Jewish physicians and medical writers; but it must be remembered that they, too, belong to Jewish literature. The most marvellous characteristic of this literature is that in it the Jewish race has registered each step of its development. "All things learned, gathered, obtained, on its journeyings hither and thither--Greek philosophy and Arabic, as well as Latin scholasticism--all deposited themselves in layers about the Bible, so stamping later Jewish literature with an individuality that gave it an unique place among the literatures of the world."
