Januarius’s life is largely unknown, but it is speculated that he was martyred during the reign of Emperor Diocletian. His body and blood were transferred to Naples, which has been attributed to several miracles. His blood is said to have halted eruptions of Mount Vesuvius, and many gather yearly to witness his blood’s liquefaction.
