Part II deals with the historical environment, the world of reference of rabbinic Judaism in Palestine and in the Hellenistic Diaspora (Reflecting Roman Religion); Part III focuses on magic and the sciences, as ancient (political and empirical) activities of influence in the double meaning of receiving and adopting something and of attempt to produce an effect on persons and objects (Performing the Craft of Sciences and Magic).
