They were both in constant communication with Babylonia on the one hand and with Spain on the other, and formed, so to speak, the link between the two lands. They lived to see the utter extinction of the Gaonate, but after their death the school of Kairuan sank into complete insignificance. One of its pupils, who afterwards became famous as a rabbinical authority, owed his fame solely to his emigration to Spain. The institutions, too, and the traditions of Babylonian-Persian Judaism showed manifest signs of decay at this time. They possessed, it is true, two men of extraordinary ability, viz. Haï and Samuel ben Chofni, but these were not in a position to stay its dissolution, and could only throw a dim light upon the dying Gaonate. Haï (or Haya, born 969, died 1038), who had in his eighteenth year been raised to the highest office next to the Gaon, at the age of thirty years succeeded his father Sherira in the Gaonate of Pumbeditha. At his installation the high honor was accorded him of having his name mentioned when a portion from the Prophets was publicly read, and he was compared to King Solomon. Foreign communities, as well as the Babylonians, showed him the highest respect. His character was noble, and he was a man of independent thought. He was versed in all branches of science as they were then taught, and displayed great literary activity. Haï reminds one of Saadiah, whom he took as his model, and whom he defended from attacks, but he was essentially a Talmudist, whereas Saadiah was a religious philosopher. Like him Haï was a thorough Arabic scholar, and made use of that language in many of his letters, and in numerous scientific treatises. Like the Gaon of Fayum he was free from that narrow-minded exclusiveness which permits men to see the truth only in their own religion, and causes them to look upon everything outside as untrue. He was on friendly terms with the head of the Eastern Christians of Bagdad, and on one occasion, when in his exegetical lectures he chanced upon a difficult passage, he did not hesitate to consult the Patriarch (Mar-Elia I.). In his explanation of rare and archaic words in the Bible, Haï boldly sought assistance from the Koran and the old traditions of the Mahometans in order to confirm their meaning. He was an unprejudiced sage, who loved the light and avoided darkness. He often had disputations with Mahometan theologians about the relation between Judaism and Islam, and is said often to have silenced them by his eloquence. His main study, however, was the Talmud. In this he resembled his father Sherira, but his study was productive of better results. He wrote a terse commentary, in which he explained the words in the most difficult portions of the Mishna and the Talmud.
