Agadeta: There are many Midrash (rabbinic interpretive commentary)im called by the name 'Aggadah (non-legal rabbinic narrative)' or 'Agadeta' that were composed by the early scholars, some of which were by Tannaim and Amoraim who compiled aggadot or interpretations. However, all of these have been lost to us, and most of the sayings were later incorporated into other Midrashim like Midrash Rabbah, Tanchuma, and more. Mentions of the early collections of Aggadot can be found in the Talmud. For example, Rav Shimi bar Ukva frequented Rabbi Shimon ben Pazi and organized Agadeta before Rabbi Yehuda HaNasi (Berachot 10). Rabbi Yochanan held a 'Sefer Aggadeta' (ibid 23). Rav Chisda said to a certain scholar who was organizing Agadeta before him (Yoma 38). Rav Chisda told Rav Tachlifa bar Avina to write 'Kanigi' and 'Blistri' in your Aggadot and explain them (Chullin 60). Rabbi Yochanan and Reish Lakish would study the 'Sefer Aggadeta' on Shabbat (the Sabbath) and interpret it (Temurah 14). We also find an 'Agadeta of Bei Rav', Rabbi Yaakov bar Acha was writing in the 'Sefer Aggadeta of Bei Rav' (Sanhedrin 56), and in the Zohar (Parashat Vayikra, page 37) and in the 'Sefera Aggadeta of Bei Rav' they say, "Even though the Torah was said from the mouth of the Almighty, everything from the mouth of Moses was said likewise". And in the 'Sefera Aggadeta of Rav Yiba Saba' it says, "From the forehead of the Ancient One" (Zohar, Parashat Haazinu, 292). And the 'Sefera of Rav Hamnuna Saba' (ibid, Parashat Pinchas, 236).
