**Rabbi Natan, author of the Aruch**, head of yeshiva in Rome, died in the year 4866. [See Yuchsin at the beginning of the later generations, and Seder HaKabbalah chapter 41, page 72] and the name of his family was Akko. And he cites in his book Rabbeinu Chananel and Rabbeinu Nissim, and Rashi cites him [(chapter 1 of Shabbat chapter 12b: in the book of the Aruch I found this impurity of a certain kind).] And I saw the book Aruch in an old manuscript with two of his poems that he composed.

And he writes that he completed the composition on the 15th...

**And it is written** [Seder HaKabbalah chapter 32b, for two and three generations after Rabbeinu HaKadosh we find many sages who composed books but we do not know the names of the authors that it is written in them that they composed in the year 1027 (should read 1028) from the conquest of the city in the days of Tzidkiyahu which is 1017 (should read 1018) to the cessation of prophecy (which was in 3448) and 1022 (should read 1038) to the destruction of the Second Temple and 4866 to creation. And I will mention some of them: Pesikta, Midrash Chazit, Midrash Tehillim, Midrash Temurah, Shiur Komah, Pirkei Heichalot, Mishnat Mishkan, Derech Eretz Rabbah and Zuta, Tractate Sofrim which the Redak in chapter 5, chapter 400 wrote was composed after the sealing of the Talmud, but Rabbati, Perek Kallah, Seder Olam, Braita of 32 Middot, Midrash Shmuel, Pirkei Eliyahu, and similar to these many.

And I saw in the book Rokeach that the author of Seder Olam was called Yosi, like the word "me'adam" which is the beginning of that book, which equals 86 with the kollel].
