GAON (pl. Geonim), formal title of the heads of the academies of Sura and Pumbedita in Babylonia. The geonim were recognized by the Jews as the highest authority of instruction from the end of the sixth century or somewhat later to the middle of the 11th. In the 10th and 11th centuries this title was also used by the heads of academies in Ereẓ Israel. In the 12th and 13th centuries – after the geonic period in the exact sense of the term – the title gaon was also used by the heads of academies in Baghdad, Damascus, and Egypt. It eventually became an honorific title for any rabbi or anyone who had a great knowledge of Torah. Apparently, the term gaon was shortened from rosh yeshivat ge'on Ya'akov (cf. "the pride of Jacob," Ps. 47:4). Other explanations of the origin of the term offered by modern scholars are not acceptable.
The Geonim of Sura and Pumbedita
The exact time when the title of gaon came into use cannot be established. *Sherira and later rabbis automatically designated as gaon the heads of the two academies from the year 900 according to the Seleucid calendar (589 C.E.), when the academies renewed their normal activity. But Sherira also mentions a tradition that Ravai, of Pumbedita (c. 540–560), was already gaon. However, some hold that this title and the special privileges of the academies were not granted until after the Arab conquest of Babylonia (657 C.E.), Sura receiving them first and later Pumbedita. Together with the title gaon they also used the titles resh metivta or rosh yeshivah ("head of the academy") as was customary in the talmudic period, and the title rosh yeshivah shel ha-golah ("head of the academy of the exile"), which is not found in the Talmud. According to a tradition that originated in the Sura academy (Neubauer, Chronicles, 2 (1895), 78), only the heads at Sura were called gaon and not their counterparts in Pumbedita. This was accepted by some historians but is contradicted by R. Sherira's account and other sources. The existence of separate traditions, one in Sura that enumerates "the qualities in which Sura is superior to Pumbedita" (ibid.), and that of Pumbedita which emphasizes that "the rabbis of Pumbedita are the leaders of the Diaspora from the time of the Second Temple" (Iggeret Rav Sherira Ga'on, ed. B.M. Lewin (1921), 82), emphasizes the competition between the two. Hints of tension and even open quarrels are found in other sources. Nevertheless, Sura and Pumbedita dominated the intellectual landscape of the period to the extent that little or nothing is known about other scholars or academies.
In the talmudic period the heads of the academies were chosen by the scholars of the academies (BB 12b) while in the geonic period they were appointed by the exilarchs. Geonim usually (although not always) rose through the hierarchy of positions in the academies until they attained this highest office. Persons of average ability therefore also attained the gaonate, and in the entire period of 400 years only a few geonim were outstanding men who made a lasting impact on Judaism. These included *Yehudai, *Amram, *Saadiah, Sherira, *Samuel b. Hophni, and *Hai. At times the exilarchs misused their authority and appointed geonim whom they expected to be subservient to them and who were not outstanding scholars. For example, it is related that an exilarch rejected *Aḥa of Shabḥa, author of the She'iltot, and appointed his disciple Natronai Kahana to the gaonate in Pumbedita (Ibn Daud, Sefer ha-Kabbalah, 47–49). Thus, the academy in Sura was generally disturbed by the interference of the exilarchs. Sherira (Iggeret Sherira Ga'on, 105) argues that because of the interference of the exilarchs he could not exactly record the names of the geonim of Sura until the year 1000 of the Seleucid calendar (689 C.E.). After the authority of the exilarchs had weakened under *David b. Judah (ibid. 93) in the times of the caliph al-Ma'mun, from 825, the influence of the group of scholars on the appointment of the gaon increased, especially in Pumbedita. Traditionally, the gaon had multiple roles. First and foremost, the gaon was the head of the academy, teaching privately and publicly, especially during the kallah months (see below). In addition, he served as judge and the head of the equivalent of a supreme court. He also was empowered to administer the courts and appoint judges. The leading geonim also wrote numerous responsa, i.e., correspondence answering halakhic questions from near and from far. As an arbiter of Halakhah, the gaon was also responsible for legal innovation when the situation warranted it. Numerous geonim were authors of commentaries, legal codes, and works of theology (see *Geonic Literature). Finally, some of the geonim were involved in politics beyond the Jewish community. They represented the community to the local and state Muslim governments.
There were cases when the exilarch and the group of scholars could not agree on the appointment of the gaon and each side appointed its own candidate. If the two sides did not reach a compromise as a result of the pressure of public opinion, the quarrel might last until the death of one of the candidates. Generally, assistants to the heads of academies were appointed gaon and were called dayyanei de-bava or av (abbreviation of av bet din). Distinguished geonim, such as Sherira, Samuel b. Hophni, and Hai had first served as av bet din; a deviation from this practice was considered derogatory. Because only those who already possessed such honorific titles as *aluf and *resh kallah and who had formerly served as scribes or assistants to heads of yeshivot, were appointed to the gaonate, the choice often fell on old men who could fill the position for only a few years.
In this period the academies in Babylonia served as the cultural center for world Jewry, and not only Babylonian-Persian Jewry as was the case in talmudic times. Hence, the influence of the geonim was now all-important. The geonim viewed themselves as the heirs to the Babylonian talmudic tradition. They continued the work of the Babylonian *amoraim as passed on by the *savoraim. This in turn was the source of their supreme authority in matters of halakhah. During the geonic period the Babylonian Talmud existed as both oral law and as written texts. Indeed, the geonim always quoted the oral tradition before citing the written texts. Since their knowledge of the Talmud was the result of an unbroken tradition, the text had a certain fluidity. The gaon would often quote from differing oral versions of the Talmud, even without determining the "correct" version. The geonim had a three-fold responsibility regarding the Talmud: (a) They were part of the chain of tradition, transmitting the Talmud to the next generation. (b) They endeavored to provide the correct interpretation of the Talmud. (c) They actively facilitated the practice of Judaism according to the Talmud. Until the second half of the 10th century, very few of their interpretations were written down. They were simply taught in the academies. Since the geonim spoke an Aramaic dialect very similar to that of the Babylonian amoraim, they had an added advantage of correctly understanding the Talmud. They clearly were intimately aware of the spirit of talmudic discourse and enjoyed a sensitivity to its literary nature. This profoundly influenced their interpretations in general and greatly affected the practical application of the Talmud text. The geonim became skilled at utilizing the advanced communication and travel technologies developed by the Muslim Empire to get their message to far-flung Jewish communities in North Africa and in Spain.
The geonim made the academies a supreme court and source of instruction for all Jewry. Thousands of persons, occupied with their personal affairs for most of the year, would assemble in the academies in the *kallah months of Elul and Adar to hear lectures on halakhah. During those months, three types of study took place: (a) A specific tractate of Talmud was studied in depth; (b) individual students were tested to see if they were worthy of the stipend; and (c) the assembly would discuss questions in halakhah, many of which were sent from throughout the Diaspora. The floor was open to all scholars. However the gaon made the final decision. The academies were actually filled with students only during the kallah months. Throughout the rest of the year, only a small group of serious students remained. These students received stipends from the academies.
While the Talmud and Talmud study were the center of the geonic universe, the geonim engaged in other areas of Jewish study. One such area is biblical exegesis. The innovator was Saadiah Gaon. Other geonim followed Saadiah's lead in writing biblical commentary; the most important of them was Samuel ben Hophni. Saadiah was the first gaon to write monographs on specific topics, a number of which he devoted to biblical translation and commentary. Saadiah translated the entire Pentateuch, as well as the books of Isaiah, Proverbs, Psalms, Job, and Daniel. He wrote commentaries on all of these books, with the exception of the latter half of the Pentateuch. Samuel ben Hophni translated and wrote commentaries on three of the five books of the Pentateuch. Each monograph begins with a lengthy and elaborate introduction in which the gaon describes the biblical text and explains the methodology of his commentary. On the whole, the commentaries emphasize the linguistic components of the text, the conflict between the literal and metaphoric meaning of the text, and theological and polemical concerns. The geonim commented on the non-legal portions of the Bible, leaving the legal sections to be dealt with in their halakhic works. At the same time, their commentaries are more disciplined and far less imaginative than earlier rabbinic exegesis. Samuel ben Hophni's commentaries do include homilies but they are not based on a specific text. Rather, they derive from the overall thrust of the whole portion of the text.
There were two major courts in Sura and two in Pumbedita. In each academy there was the gaon's court and that of the av bet din. In addition, the gaonate had jurisdiction over the organization of the courts in all the districts of Babylonia. However, the judges were appointed by the exilarch with the assent of the geonim. Only under Hai Gaon did the supreme court (bet din ha-gadol) of Pumbedita appoint the judges (Neubauer, Chronicles, 2 (1887), 85; Teshuvot ha-Ge'onim, ed. Harkavy, no. 180). The geonim were not satisfied with halakhic conclusions derived from the Talmud; they also made new regulations regarding contemporary needs. Their takkanot ("ordinances") had legal validity because the geonim considered themselves presidents of the Sanhedrin of their generation. The halakhic decisions of the geonim were not made without influence from the general, non-Jewish legal environment. It has been demonstrated that a number of geoniccustoms had their origins in Islamic practice. For example, the question arose as to how a widow who lost her *ketubbah would receive payment. Ẓemah Gaon suggested that the determination should be made by consulting the ketubbot of her relatives. Both Sherirah and Hai disagreed with this ruling because it had no basis in the Talmud. However, a similar practice existed in Islamic law. Interestingly, the custom was accepted by later authorities, including Solomon *Duran, Solomon *Aderet and *Asher ben Jeḥiel.
All these tasks required a large establishment; therefore, the academies employed scribes, directors of the kallah assemblies, and other officials. Their expenditure was covered by taxes levied on districts, which were directly subject to their authority. In addition, the communities which addressed their questions to the geonim sent them contributions. In isolated instances the geonim would turn to the communities in the Diaspora with a request for financial support and usually their request was answered. Real estate also served as a source of income for the academies. The requests for support of the academies increased, especially, toward the end of the geonic period. Thus, the candidates for the office of head of the academies
On the appointment of a new gaon a festive ceremony was held, in which participated the scholars of the two academies and the dignitaries of all the communities in Babylonia, headed by the exilarch. According to *Nathan ben Isaac ha-Bavli (Neubauer, Chronicles 2 (1895), 86), the ceremony resembled the installation of the exilarch and the people honored the geonim royally. Following the method of talmudic references to heads of academies, Sherira throughout used the word "malakh" ("reigned") to designate the term of service of the gaon.
The geonim were considered the intellectual leaders of the entire Diaspora and their decisions and responsa had absolute legal validity in most Jewish communities. It cannot be assumed that they attained their influence without a struggle and conflict with other centers, especially Ereẓ Israel. Ben Baboi (see *Pirkoi Ben Baboi) the pupil of Yehudai Gaon, attested to the intervention of the geonim in the affairs of Ereẓ Israel, "and he wrote to Ereẓ Israel regarding… all the mitzvot which are not observed properly according to the halakhah but according to practice in times of persecution and they did not accept his intervention and they replied to him: 'a custom suspends a halakhah'" (Ginzberg, Ginzei Schechter, 2 (1929), 559). Baboi attacked practices of Ereẓ Israel (Tarbiz, 2 (1931), 396–7). He claimed that only the Babylonian customs and practices were valid. To follow the customs of Ereẓ Israel was a sin. Seventy years later, Amram polemized against those who followed the customs of the westerners who deviated from the right path. The aim of the Babylonian geonim was to impose the Babylonian Talmud and the doctrines of their academies also in Ereẓ Israel and in this way to lessen the attachment of the Diaspora to Ereẓ Israel.
The gaonate had a specific political, communal function at the side of the exilarch. The recognition of the gaonate as a political representation of the Jewish community is attested by the fact that on the death of the exilarch his income was given to the gaon of Sura until the appointment of a new exilarch. The geonim also attempted to influence the policy of the government toward the Jews via Baghdad Jewry, who had representatives in the court of the caliphs. However, the particular achievement of the geonim was their success in giving legal validity to the laws of the Talmud and spreading the knowledge of the Talmud among the thousands of people who came to Babylonia from all parts of the world. Their writings in the fields of commentary and halakhah made an impact on the entire period which is named after them. Their great importance to Jewry is attested by the paragraph in the *Kaddish where the geonim are mentioned together with the exilarch (Gedenkbuch… D. Kaufmann (1900), Hebrew section, 52ff.; Ginzei Kedem, 2 (1923), 46; 3 (1925), 54). They and other high officials in the academies are also mentioned with the exilarch in the prayer Yekum Purkan. R. *Ẓemaḥ b. Ḥayyim, the gaon of Sura, expressed this feeling of authority in his responsa to the community in Kairouan: "And when Eldad said that they pray for the scholars of Babylonia and then for those in the Diaspora, they are right. For the major scholars and prophets were exiled to Babylonia, and they established the Torah and founded the academy on the Euphrates under Jehoiachin, king of Judah until this day, and they were the dynasty of wisdom and prophecy and the source of Torah for the entire people…" (Eldad ha-Dani, ed. by Abraham Epstein (1891), 8).
Even though the leading geonim were those of the later generations, the gaonate already had declined as the cultural, religious center of Judaism far before it had ceased to exist. This was as a result of a combination of internal and external causes. A sign of its public decline was that from the late ninth century most geonim no longer lived in the cities of the two academies. They lived in Baghdad, the center of the authorities and the residence of the exilarch. On the one hand, the decline of the academies in the eyes of the Diaspora was caused by the competition between Sura and Pumbedita and the quarrels in the academies regarding the appointment of the gaon. On the other hand, the essence of the fulfillment of the mission of the geonim– the spread of the Talmud – lessened its importance. With the emergence of new centers for talmudic studies and the appearance of great scholars throughout the Diaspora, its dependence on the two academies and on the geonim ceased and its attachment to them weakened. Independent-minded scholars stopped sending questions to the academies and their geonim, and even important geonim such as Sherira and Hai expressed their anger at the weakening of the links with North Africa and with Spain (Mann, Texts, 1 (1931), 109, 120–1). *Ḥanokh b. Moses of Cordoba did not even answer the letters of *Sherira. The scholars of Spain found encouragement from the authorities in their tendency to break their dependence on the geonim of Babylonia. The Umayyad caliphs in Cordoba did not approve the
The decline of the Baghdad caliphate, the impoverishment of Babylonian Jewry which caused the academies to depend completely on contributions from abroad, the greatness and the independent intellectual development of the Diaspora, and the persecutions by the Abbasid and Seljuk rulers put an end to the institution of the gaonate in about 1040.
List of the Geonim of Sura and Pumbedita
Because of the dearth of sources the exact chronology of the geonim cannot be established. The letter of R. Sherira serves asthe basis for the list but it contains contradictions and many variant versions. (See Table: Chronological List of Geonim in Sura and Pumbedita.) The list of Abraham *Ibn Daud in the Sefer ha-Kabbalah does not clarify these contradictions. Nonetheless, the letter of Sherira remains the major source for the chronology of the Babylonian geonim. But there is much material on the history of their period, both in Babylonia and in other countries, in the collections of the responsa of the geonim (see bibliography).
[Simha Assaf and
The collecting of scattered material in the anthologies of geonic responsa, both printed and in manuscript, and in their editing, according to the order of the tractates of the Babylonian Talmud, was begun by B.M. Lewin in Oẓar ha-Ge'onim, which he published in 12 volumes to Bava Kamma (1928–43). The 13th volume was published posthumously to part of Bava Meẓia and one volume of Oẓar ha-Ge'onim to Sanhedrin was published by H.Z. Taubes (Jerusalem, 1966).
The following are the editions of geonic responsa: Halakhot Pesukot min ha-Ge'onim (Constantinople, 1516, and again published by J. Mueller, 1893); She'elot u-Teshuvot me-ha-Ge'onim (Constantinople, 1575); Sha'arei Ẓedek (Salonika, 1792; Jerusalem, 1966); Sha'arei Teshuvah (in Naharot Dammesek of Solomon Kamondo, Salonika, 1802, and separately; Leipzig, 1858; Leghorn, 1869; New York, 1946); Teshuvot Ge'onim Kadmonim (Berlin, 1848); Ḥemdah Genuzah (Jerusalem, 1863); Toratam shel Rishonim (published by Ch. M. Horowitz, Frankfort, 1881); Teshuvot Ge'onei Mizraḥ u-Ma'arav (published by J. Mueller, Berlin, 1888); Kohelet Shelomo (published by S.A. Wertheimer, Jerusalem, 1899); Ge'on ha-Ge'onim (published by S.A. Wertheimer, Jerusalem, 1925); Mi-Sifrut ha-Ge'onim (published by S. Assaf, Jerusalem, 1933); Teshuvot ha-Ge'onim (standard title for different texts), published by J. Musafia (Lyck, 1864); by N.N. Coronel (Vienna, 1871); by A. Harkavy (Berlin, 1887); by S. Assaf (Jerusalem, 1927, 1928, 1942); by A. Marmorstein (Déva, 1928). Geonic responsa appeared also in several anthologies and periodicals such as Ta'am Zekenim (ed. by E. Askenazi, 1855); Oẓar ha-Ḥayyim (ed. by Ch. Ehrenreich, 1925–38); Ginzei Kedem (1922–44); in REJ, JQR, Tarbiz, KS, Sinai (see their index volumes), and in various Festschriften.
The Geonim of Baghdad after the Geonic Period
The heads of the Baghdad academy saw themselves as the successors of the geonim of Sura and Pumbedita because the last of them had lived in Baghdad after the tenth century. It may be assumed that many students and teachers from the older academies came to the academy that opened in the second half of the 11th century. The heads of the academies in Baghdad attempted to preserve, if at all possible, the continuity of their connection with the geonic period and called themselves, in the manner of their predecessors in Sura and Pumbedita, rosh yeshivat ge'on Ya'akov and rosh yeshivah shel ha-golah. The first known Baghdad gaon was Isaac b. Moses b. Sakri who came to the East from Spain in about 1070 after he failed to receive recognition in his native country. There is no information on the academy of Babylon, except for the period of 1140–50 when its head was Eli ha-Levi, the rabbi of David *Alroy. The names of the geonim who followed him are known from letters and responsa. The most famous was *Samuel b. Ali ha-Levi who opposed *Maimonides; he is praised by the travelers *Benjamin of Tudela and *Pethahiah of Regensburg. Judah *Al-Ḥarizi found that the liturgical poet *Isaac b. Israel ibn Shuwaykh was the head of the Baghdad academy. He was also known because of his connections with Abraham *Maimuni. In 1258 Baghdad Jewry was threatened by the attack of the Mongols and with the decline of Babylonian Jewry the position of gaonate declined as well. In 1288 the head of the Baghdad academy was Samuel b. Abi al-Rabīʿa ha-Kohen. This is known from his letter concerning the Maimonidean controversy (published by Halberstam in J. Kobak's Jeschurun, vol. 7, pp. 76–80). Henceforth, nothing is known about the fate of the Baghdad academy in the Middle Ages.
The Gaonate in Ereẓ Israel
Little information on the beginnings of the gaonate in Ereẓ Israel is available. Sources increase only in the beginning of the 10th century as a result of the dispute between Saadiah Gaon
The geonim of Ereẓ Israel in the 10th and 11th centuries were mainly from the family of Ben Meir, which claimed relation to *Judah ha-Nasi and thus to King David, and two families of kohanim, one of which was the family of *Abiathar and was related to *Eleazar b. Azariah. However, S. Abramson concludes that the family of kohanim that claimed relation to the House of David stemmed from the academy in Ereẓ Israel in one family. Abramson discovered in the Genizah fragments of an unknown document, which contained a list of the heads of academies for several generations. From this document it is apparent that one family of kohanim was merely a branch of the Ben Meir family. Thus, the gaonate of Ereẓ Israel was held by one family and its different branches for perhaps 200 years. *Solomon b. Judah, a native of Fez, next to Ben Meir the most famous of the geonim in Ereẓ Israel and whose family is not known, and his successor *Daniel b. Azariah, a descendant of one of the families of the exilarchate in Babylonia, were heads of academies and were not descendants of the geonim of Ereẓ Israel. Daniel was known as a strong leader, was esteemed by his contemporaries, and was a friend of Samuel ha-Nagid (Ibn Nagrela).
Besides managing the academy, the work of the gaon included all Jewish affairs in Ereẓ Israel. The designation of powers among the heads of academies and exilarchs, as was practiced in Babylonia, was not known in Ereẓ Israel. The geonim ordained the ḥaverim, appointed the dayyanim in Ereẓ Israel and Syria, and managed the economic affairs of the Jewish community in Ereẓ Israel. They were recognized by the foreign ruler as the representatives of the Jewish community in Ereẓ Israel. After Ereẓ Israel was politically allied with Baghdad and later with Egypt, the geonim corresponded with highly influential Jewish dignitaries in the two capitals. In these cases of emergency they were accustomed to travel there personally to negotiate in the court of the rulers. The halakhic and literary activity of the geonim is attested by some responsa. Hundreds of letters asking the geonim to aid the Jewish community and the academies were discovered in the Cairo Genizah. The geonim of Ereẓ Israel were not as learned as the geonim in Babylonia. Their major achievement was the maintenance of the continuity of the tradition of the academies in Ereẓ Israel under difficult political conditions.
Abrahamson assumes that Ẓemaḥ, who served as head of the academy from about 884–915, was a fourth-generation descendant of *Anan b. David, the founder of the Karaites, and he was a nasi and a gaon. Aaron Ben Meir succeeded in deposing Anan's family only after a bitter struggle in which he was assisted by the scholars and heads of the Baghdad community.
The Geonim of EreẒ Israel in Damascus, and the Geonim of Egypt
The occupation of Jerusalem by the Seljuks in 1071 completely destroyed the city's Jewish community. The gaon *Elijah b. Solomon moved the academy to Tyre, which was subject to Fatimid rule. Elijah's son Abiathar headed the Tyre academy until the conquest of the city by the crusaders. Afterward he moved to Tripoli, Syria, where he died before 1110. His brother Solomon, who served as an av bet din, fled in 1093 to Hadrak (near Damascus) because of the decrees of David b. Daniel b. Azariah, head of Egyptian Jewry. In Hadrak he assembled the survivors of the Ereẓ Israel academy which apparently included his brother's son Elijah b. Abiathar. Later his position was given to his son Maẓli'aḥ, who went to Egypt in 1127 where he received the title of gaon. The academy of Ereẓ Israel was moved from Hadrak to Damascus and still existed during the 12th century when *Benjamin of Tudela reported that it was subject to the rule of the Babylonian gaonate (Baghdad). The names of two geonim who were descendants of the Abiathar family, Abraham b. Mazhir and his son Ezra, are known. The latter was ordained by Samuel b. Ali of Baghdad. In his time or shortly afterward the continuity of the geonim of Ereẓ Israel was broken. It is possible that he was followed by Zadok, who was dismissed from his position (Taḥkemoni, ed. by A. Kaminka (1899), 354).
In Fostat, Egypt, the academy existed in the time of Elhanan, the father of Shemariah, who is known from the story of the "*Four Captives." His title "chief rabbi" and his position were inherited by his son and then his grandson Elhanan who called himself rosh ha-seder or "rosh ha-seder of all Israel." *Shemariah and Elhanan, both of whom had previously studied in the Pumbedita academy, corresponded with Sherira and Hai. Only after the decline of the Babylonian and Palestinian academies did the large communities in Egypt request the establishment of their own gaonate. David b. Daniel (1083–89) was the first who attempted to do this. Like his strict father, he hoped to become nasi and gaon and to exert his power even over the head of the Tyre academy and on the communities in the coastal cities of Ereẓ Israel. However, the nagid Mevorakh, who supported him at first, later rejected him. In 1127 Maẓliaḥ b. Solomon, the aged head of the Ereẓ Israel academy, moved from Hadrak to Fostat and called himself rosh yeshivat ge'on Ya'akov. Several of his documents and letters are extant. After his death in 1138, his position was apparently given to Moses ha-Levi b. Nethanel; however, it is possible that Samuel b. Hananiah, who met Judah Halevi when he traveled from Egypt to Ereẓ Israel, was given the position. After Moses, his son Nethanel was gaon (1160–70) and was followed on his death by his brother Sar Shalom who was appointed gaon at Fostat. Sar Shalom, who was perhaps of Palestinian geonic descent, sometimes called himself rosh yeshivat Ereẓ ha-Ẓevi, as if his activities were a continuation of the academies of Ereẓ Israelnot only in Damascus but also in Fostat. With his death the gaonate in Egypt ceased to exist. Maimonides, who lived at that time in Egypt, did not possess the title of gaon.
The Title of Gaon in Other Countries
The title of gaon was also used by great scholars in other countries. Maimonides writes in his introduction to the Mishneh Torah, "the geonim of Spain and France." The geonim of Africa, Lotharingia (Lorraine), Mainz, and Narbonne are mentioned in the literature of the early posekim. Thus, the title was given to well-known individuals from the early rabbinic period, such as R. *Hananel, R. *Nissim, R. *Moses b. Ḥanokh and his son *Ḥanokh, R. *Joseph b. Abitur, R. Kalonymus of Lucca and his son R. Meshullam, and others.
