A 4th-century bishop and martyr, he is famous for the miracle of the liquefaction of his blood, preserved in ampoules in Naples, which occurs several times a year.
Saint Januarius, or San Gennaro, was Bishop of Benevento in Campania. He was martyred around 305 during the Diocletianic Persecution, likely decapitated near Pozzuoli. His story is inseparable from the famous miracle of the liquefaction of his blood, preserved in a vial and presented several times a year in Naples, an event considered a sign of protection for the city and its inhabitants. His devotion is particularly strong in Southern Italy and among the Neapolitan diaspora.
