More on the festivals of the non-Jews, including, specifically, the coronation of their kings. With specific focus on the coronation of a king born of a king - except that the Romans didn't really function that way. So perhaps it was the king's birthday, not his coronation day? The Gemara attempts to unravel the terms. Also, Antoninus, about whom there are many stories with Rabbi Yehudah HaNasi, a caesar who hated the Jews, and the role of circumcision in defining the Jewish community.
