An Ancient Secret Ritual

Have you heard of a 'secret ritual'?
It's apparently a special ritual that a certain group of people had kept secret from outsiders for a long time. There's apparently a temple which had been famous for its secret ritual in Rome since ancient times. It's said that even an emperor of Rome participated in it.
This is a request from a scholar to find this temple. The scholar in Naples should know something more about it.
