In 1549, the rabbinical court in Cairo held hearings and engaged in extensive research to learn about the source of the annual flooding of the Nile.

Are our dreams significant? Do they have predictive value? Should we pay heed to their warnings? The Talmud seems to offer contradictory teachings on this subject, and this will lead us toward two classic approaches to this matter. The Meaning of Dreaming: Talmudic Perspectives

As Italian Jews immigrated to the Ottoman Empire during the sixteenth century, many wanted to switch to the Sephardic liturgical style.
