 According to legend, Christianity was introduced into Caiazzo by St. Priscus, one of the seventy-two disciples of Jesus Christ, first Bishop of Capua.The story is universally rejected.The first known bishop of Caiazzo was said to have been Arigisus, the exact time of whose episcopate is uncertain; however, as the name indicates, it could not have been before the beginning of the seventh century, when the Lombards settled in that region, since his name appears to be Lombard.
