The Babylonian Talmud remains the richest source of information regarding the material culture and lifestyle of the Babylonian Jewish community, with additional data now supplied by Babylonian incantation bowls. Although archaeology has yet to excavate any Jewish sites from Babylonia, information from Parthian and Sassanian Babylonia provides relevant background information, which differs substantially from archaeological finds from the Land of Israel. One of the key questions addresses the amount of traffic and general communications between Jewish Babylonia and Israel, considering the great distances and hardships of travel involved.
