Menachem's defenders endeavored to appeal to Chasdaï's love of truth, and to make him the arbiter against Dunash, "who set himself up as the chief of commentators, who knows neither law nor limit of change, and who desecrates and spoils the holy language through his foreign meter." The study of the Hebrew language was carried on in Spain by means of severe contention and virulent satire. The pupils of Dunash continued the quarrel. The followers of Menachem and Dunash hurled witty lampoons against each other, which fact contributed largely towards making the Hebrew language at once pliant and rich. As Chasdaï Ibn-Shaprut had given an impulse to various poets and writers by means of encouragements and rewards, so also he founded a home in Spain for the study of the Talmud. Jewish science in Europe had not yet attained a sufficiently firm footing to enable it to dispense with the fostering care of a protector. Moses ben Chanoch, too, who had been chosen to collect contributions for the school of Sora, and who had been brought as a slave to Cordova and there redeemed, found a patron in Chasdaï, and the two Caliphs who were friendly to science beheld with pleasure the study of the Talmud springing up in their realms, because it would tend to sever their Jewish subjects from the Caliphate of Bagdad. Moses could have come to Spain at no more favorable time for establishing firmly the study of the Talmud, without which the literary activity just springing up could not have made progress. Just as the Spanish Moors had busied themselves with the task of casting the Caliphate of Bagdad into the shade, in the hope of monopolizing all political and literary distinctions, so the Spanish Jews longed to obscure the Babylonian schools, and to transfer to the school which Moses had opened in Cordova the supremacy which the former had hitherto enjoyed, owing to the deeper knowledge of the Talmud there.
