**In the year 4905 Rabbi Elazar** bar Natan of Toul called Ravan was an Ashkenazi, a great sage, and composed compositions. [The book Ravan or Even HaEzer, printed Prague 5370, and Tzafnat Paane'ach.] Rabbi Elazar bar Meshulam and Rabbi Eliezer bar Rabbi Meir bar Yitzchak of Orleans were elders in this generation. [And Rashi mentions them in his commentary on the Tur.] Rabbi Yosef, an important student of the Rambam [who composed a commentary on Song of Songs in Arabic]. Rabbi Elikum bar Yosef, a great sage and teacher of rulings. [And I saw in an old Kuntres that he was the father-in-law of Ravan and they were together, as is seen in Mordechai in Tractate Rosh Hashanah chapter 9, where he says "an incident occurred in Mainz in the year 4905 before Rabbeinu Elikum and Ravan." And it is seen that Rashbam, brother of Rabbeinu Tam, grandson of Rashi, was in their days, great and a teacher of rulings, as is seen in Hagahah in Rambam, Laws of Marriage, chapter 2, which writes "and there was an incident and Rabbeinu Elikum bar Yosef and Ravan agreed to one opinion and they asked Rashbam and he agreed with them," etc.
And likewise in Mordechai HaKetuvot chapter HaIshah, Ravan and Rabbi Elikum asked Rashbam, etc.] Rabbeinu Yitzchak bar Mordechai lived in this generation, a great sage in Regensburg, and the Mordechai mentions him in Rosh Hashanah chapter 9 and in other places. Rabbeinu Shimshon bar Tuvia called Rashbat, a great sage in this generation, for he was the son-in-law of Ravan as is seen in Hagahot HaMaimon at the end of the laws of chametz and matzah, and the poskim cite his opinion.
Rabbeinu Yoel HaLevi [(bar Yitzchak of Bonn. Responsa Maharshal section 29)] was the son-in-law of Ravan and was a great sage and he had a son called Raavyah. Rabbeinu Yoel, son of Ravan, called Rivan, was a great sage and composed compositions. And it says in Mordechai Chulin chapter Kol HaBasar that he composed a book called Dah.
And in Yuchsin, Rivan was a student of Rashi and so was Rabbi Shemaya [(see year 4906)]. And Rivan HaLevi the young man who was killed for the sanctification of HaShem lived in this generation. And I saw in Rambam that Rabbi Shemarya wrote from the mouth of Rivan [(Seder HaKabbalah chapter 50, page 71). The Maharshal wrote in Responsa section 29: Ravan received from Rabbi Yaavatz and from his father-in-law Rabbi Elikum bar Yosef.
And the sons-in-law of Ravan were Rabbi Yitzchak HaLevi and Rabbi Shmuel bar Natronai. And his son Rabbi Mordechai of Klininin and his son Rabbi Shlomo of Broylo and his son Rabbi Yehuda called Lieberman of Freiburg. And his son Shlomo and Rabbi Uri, thus concluded.] Ravan was the grandfather of the Redak and of the Mordechai, [as the Tur chapter 145, page 71 states].
