Resonances of Samuel David Luzzatto's characterization of Italian Jewry can be heard in the personal memoirs of Arnaldo Momigliano. Pagan, Jewish, and Christian -these were the three civilizations which dominated Momigliano's life work. Between 1930 and 1934 Momigliano wrote four major works on representative areas of the triple civilizations: one on the Maccabean tradition; two articles on Josephus' defense of Judaism, the Contra Apionem; a presentation of his conception of first century Pharisaic Judaism; and Alien Wisdom, in which he explored (...) the Hellenistic discovery of Jews, Celts, Romans, and Iranians, and Rome's meeting of these cultures. Momigliano's discussions of the ways that Judaism both absorbed GrecoRoman culture and reacted to it should be taken into account when examining the central texts of rabbinic literature, for the Rabbis themselves were conscious that they belonged to the triple civilizations. Through an analysis of the Midrash, it is shown that Momigliano helps us to appreciate some of the characteristics which emunah holds in common with pistis or fides. An example of the way Jews reacted to the imposition of Roman rule is given in their reaction to the imperial cult. (shrink)
