of the Midrash Aggadah received a mighty impetus, and the foundations were laid for public services which were soon to offer the chief medium for the cultivation of Bible exegesis. Much Aggadah, often mixed with foreign elements, is found in the Apocrypha, the Pseudepigrapha, the works of Josephus and Philo, and the remaining Judæo-Hellenistic literature; but aggadic exegesis reached its highest development in the great epoch of the Mishnaic-Talmudic period, between 100 and 550 CE. The Aggadah of the Amoraim (sages of the Talmud) is the continuation of that of the Tannaim (sages of the Mishna). The final edition of the Mishnah, which was of such signal importance for the Halakah, is of less significance for the Aggadah, which, in form as well as in content, shows the same characteristics in both periods. Exegetic and homiletic Aggadah It is important to emphasize the fundamental difference in plan between the midrashim forming a running commentary (מאמרים ביאוריים) to the Scripture text, and the homiletic midrashim (מאמרים לימודיים). When the scholars undertook to edit, revise, and collect into individual midrashim the immense array of haggadot, they followed the method employed in the collections and revisions of the halakhot and the halakhic discussions. The form which suggested itself was to arrange in textual sequence the exegetical interpretations of the Biblical text as taught in the schools, or the occasional interpretations introduced into public discourses, etc., and which were in any way connected with Scripture. Since the work of the editor was often merely that of compilation, the existing midrashim show in many passages the character of the sources from which they were taken. This was the genesis of the midrashim which are in the nature of running haggadic commentaries to single books of the Bible, as Bereshit Rabbah, Eikah Rabbati, the midrashim to the other Megillot, etc. See Midrash for more details. Modern compilations Ein Yaakov is a compilation of the aggadic material in the Babylonian Talmud together with commentary. It was compiled by Jacob ibn Habib and (after his death) by his son Levi ibn Habib, and was first published in Saloniki (Greece) in 1515. It was intended as a text of aggadah, that could be studied with "the same degree of seriousness as the Talmud itself". Popularized anthologies did not appear until more recently—these often incorporate "aggadot" from outside of classical Rabbinic literature. The major works include: Sefer Ha-Aggadah (The Book
