The early history of the synagogue is controverted, but it seems to be an institution developed for public Jewish worship during the Babylonian captivity when the Jews did not have access to the Jerusalem Temple for ritual sacrifice. Instead, to give a rough summary, they developed a daily and weekly service of readings from the Torah or the prophets followed by commentary. This could be carried out in a house if the attendance was small enough, and in many towns of the Diaspora that was the case. In others more elaborate architectural settings developed, sometimes by converting a house and sometimes by converting a previously public building.
